Installation
Download Stand alone FireFox with AuraPlayer IDE - link
Unzip the above file, and open FirefoxPortable.exe.
Opening the IDE
To run the AuraPlayer IDE, simply select it from the Firefox Tools menu. It opens as follows with an empty script-editing window and a menu for loading, or creating new workflows.
IDE Features
Toolbar
The toolbar contains buttons for controlling the execution of your Workflows, including a step feature for debugging your Workflows. The right-most button, the one with the red-dot, is the record button.
- Speed Control: controls how fast your Workflow runs.
- Run All: Runs the entire test suite when a test suite with multiple Workflows is loaded.
- Run: Runs the currently selected test. When only a single test is loaded this button and the Run All
- button have the same effect.
- Pause/Resume: Allows stopping and re-starting of a running Workflow.
- Step: Allows you to “step” through a Workflow by running it one command at a time. Use for debugging Workflows.
- TestRunner Mode: Allows you to run the Workflow in a browser. The TestRunner is not commonly used now and is likely to be deprecated. This button is for evaluating Workflows for backwards compatibility with the TestRunner. Most users will probably not need this button.
Insert Input command: Allows you to store a value as an input
Insert Output command: Gets the text of an element. This works for any element that contains text.
- Record: Records the user’s browser actions.
Workflow Pane
Your script is displayed in the Workflow pane. It has two tabs, one for displaying the command and their parameters in a readable “table” format.
The other tab - Source displays the Workflow in the native format in which the file will be stored. By default, this is HTML although it can be changed to a programming language such as Java or C#, or a scripting language like Python. See the Options menu for details. The Source view also allows one to edit the Workflow in its raw form, including copy, cut and paste operations.
The Command, Target, and Value entry fields display the currently selected command along with its parameters. These are entry fields where you can modify the currently selected command. The first parameter specified for a command in the Reference tab of the bottom pane always goes in the Target field. If a second parameter is specified by the Reference tab, it always goes in the Value field.
If you start typing in the Command field, a drop-down list will be populated based on the first characters you type; you can then select your desired command from the drop-down.
Log/Reference/UI-Element/Rollup Pane
The bottom pane is used for four different functions–Log, Reference, UI-Element, and Rollup–depending on which tab is selected.
Log
When you run your Workflow, error messages and information messages showing the progress are displayed in this pane automatically, even if you do not first select the Log tab. These messages are often useful for Workflow debugging. Notice the Clear button for clearing the Log. Also notice the Info button is a drop-down allowing selection of different levels of information to log.
Reference
The Reference tab is the default selection whenever you are entering or modifying commands and parameters in Table mode. In Table mode, the Reference pane will display documentation on the current command. When entering or modifying commands, whether from Table or Source mode, it is critically important to ensure that the parameters specified in the Target and Value fields match those specified in the parameter list in the Reference pane. The number of parameters provided must match the number specified, the order of parameters provided must match the order specified, and the type of parameters provided must match the type specified. If there is a mismatch in any of these three areas, the command will not run correctly.
UI-Element and Rollup
Detailed information on these two panes (which cover advanced features) can be found in the UI-Element Documentation on the Help menu of AuraPlayer IDE.
Building Workflows
There are three primary methods for developing Workflows. Frequently, a test developer will require all three techniques.
Recording
Many first-time users begin by recording a Workflow from their interactions with a website. When AuraPlayer IDE is first opened, the record button is ON by default. If you do not want AuraPlayer IDE to begin recording automatically you can turn this off by going under Options > Options… and deselecting “Start recording immediately on open.”
During recording, AuraPlayer IDE will automatically insert commands into your Workflow based on your actions. Typically, this will include:
- clicking a link - click or clickAndWait commands
- entering values - type command
- selecting options from a drop-down listbox - select command
- clicking checkboxes or radio buttons - click command
Here are some “gotchas” to be aware of:
- The type command may require clicking on some other area of the web page for it to record.
- Following a link usually records a click command. You will often need to change this to clickAndWait to ensure your Workflow pauses until the new page is completely loaded. Otherwise, your Workflow will continue running commands before the page has loaded all its UI elements. This will cause unexpected Workflow failures.
Running Workflows
The IDE allows many options for running your Workflow. You can run a Workflow all at once, stop and start it, run it one line at a time, run a single command you are currently developing, and you can do a batch run of an entire test suite. Execution of Workflows is very flexible in the IDE.
- Run a Workflow
- Click the Run button to run the currently displayed Workflow.
- Run a Test Suite
- Click the Run All button to run all the Workflows in the currently loaded test suite.
- Stop and Start
- The Pause button can be used to stop the Workflow while it is running. The icon of this button then changes to indicate the Resume button. To continue click Resume.
- Stop in the Middle
- You can set a breakpoint in the Workflow to cause it to stop on a particular command. This is useful for debugging your Workflow. To set a breakpoint, select a command, right-click, and from the context menu select Toggle Breakpoint.
- Start from the Middle
- You can tell the IDE to begin running from a specific command in the middle of the Workflow. This also is used for debugging. To set a startpoint, select a command, right-click, and from the context menu select Set/Clear Start Point.
- Run Any Single Command
- Double-click any single command to run it by itself. This is useful when writing a single command. It lets you immediately test a command you are constructing, when you are not sure if it is correct. You can double-click it to see if it runs correctly. This is also available from the context menu.
Using Base URL to Run Workflows in Different Domains
The Base URL field at the top of the AuraPlayer IDE window is very useful for allowing Workflows to be run across different domains. Suppose that a site named http://news.portal.com had an in-house beta site named http://beta.news.portal.com. Any Workflows for these sites that begin with an open statement should specify a relative URL as the argument to open rather than an absolute URL (one starting with a protocol such as http: or https:).AuraPlayer IDE will then create an absolute URL by appending the open command’s argument onto the end of the value of Base URL. For example, the Workflow below would be run against http://news.portal.com/about.html:
This same Workflow with a modified Base URL setting would be run against http://beta.news.portal.com/about.html:
Commands
Commands, are the set of commands that run your tests. A sequence of these commands is a test script. Here we explain those commands in detail, and we present the many choices you have in testing your web application.
One can test the existence of UI elements based on their HTML tags, test for specific content, test for broken links, input fields, selection list options, submitting forms, and table data among other things. In addition commands support testing of window size, mouse position, alerts, Ajax functionality, pop up windows, event handling, and many other web-application features.
A command tells AP what to do. commands come in three “flavors”: Actions, Accessors, and Assertions.
-
Actions are commands that generally manipulate the state of the application. They do things like “click this link” and “select that option”. If an Action fails, or has an error, the execution of the current test is stopped.
Many Actions can be called with the “AndWait” suffix, e.g. “clickAndWait”. This suffix tells that the action will cause the browser to make a call to the server, and that should wait for a new page to load.
-
Accessors examine the state of the application and store the results in variables, e.g. “storeTitle”. They are also used to automatically generate Assertions.
-
Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include “make sure the page title is X” and “verify that this checkbox is checked”.
All Assertions can be used in 3 modes: “assert”, “verify”, and ” waitFor”. For example, you can “assertText”, “verifyText” and “waitForText”. When an “assert” fails, the test is aborted. When a “verify” fails, the test will continue execution, logging the failure. This allows a single “assert” to ensure that the application is on the correct page, followed by a bunch of “verify” assertions to test form field values, labels, etc.
“waitFor” commands wait for some condition to become true (which can be useful for testing Ajax applications). They will succeed immediately if the condition is already true. However, they will fail and halt the test if the condition does not become true within the current timeout setting (see the setTimeout action below).
Script Syntax
Commands are simple, they consist of the command and two parameters. For example:
verifyText | //div//a[2] | Login |
The parameters are not always required; it depends on the command. In some cases both are required, in others one parameter is required, and in still others the command may take no parameters at all. Here are a couple more examples:
goBackAndWait | ||
verifyTextPresent | Welcome to My Home Page | |
type | id=phone | (555) 666-7066 |
type | id=address1 | ${myVariableAddress} |
The command reference describes the parameter requirements for each command.
Parameters vary, however they are typically:
- a locator for identifying a UI element within a page.
- a text pattern for verifying or asserting expected page content
- a text pattern or a variable for entering text in an input field or for selecting an option from an option list.
Locators, text patterns, variables, and the commands themselves are described in considerable detail in the section on Commands.
Scripts that will be run from AuraPlayer IDE will be stored in an HTML text file format. This consists of an HTML table with three columns. The first column identifies the command, the second is a target, and the final column contains a value. The second and third columns may not require values depending on the chosen command, but they should be present. Each table row represents a new command. Here is an example of a test that opens a page, asserts the page title and then verifies some content on the page:
<table>
<tr><td>open</td><td>/download/</td><td></td></tr>
<tr><td>assertTitle</td><td></td><td>Downloads</td></tr>
<tr><td>verifyText</td><td>//h2</td><td>Downloads</td></tr>
</table>
Rendered as a table in a browser this would look like the following:
open | /download/ | |
assertTitle | Downloads | |
verifyText | //h2 | Downloads |
The HTML syntax can be used to write and run tests without requiring knowledge of a programming language. With a basic knowledge of HTML and AuraPlayer IDE you can quickly produce and run Workflows.
Commonly Used Commands
To conclude our introduction of AuraPlayer IDE, we’ll show you a few typical commands. These are probably the most commonly used commands for building tests.
- open
- opens a page using a URL.
- click/clickAndWait
- performs a click operation, and optionally waits for a new page to load.
- verifyTitle/assertTitle
- verifies an expected page title.
- verifyTextPresent
- verifies expected text is somewhere on the page.
- verifyElementPresent
- verifies an expected UI element, as defined by its HTML tag, is present on the page.
- verifyText
- verifies expected text and its corresponding HTML tag are present on the page.
- verifyTable
- verifies a table’s expected contents.
- waitForPageToLoad
- pauses execution until an expected new page loads. Called automatically when clickAndWait is used.
- waitForElementPresent
- pauses execution until an expected UI element, as defined by its HTML tag, is present on the page.
Verifying Page Elements
Verifying UI elements on a web page is probably the most common feature of your automated tests. Commands allows multiple ways of checking for UI elements. It is important that you understand these different methods because these methods define what you are actually testing.
For example, will you test that…
- an element is present somewhere on the page?
- specific text is somewhere on the page?
- specific text is at a specific location on the page?
For example, if you are testing a text heading, the text and its position at the top of the page are probably relevant for your test. If, however, you are testing for the existence of an image on the home page, and the web designers frequently change the specific image file along with its position on the page, then you only want to test that an image (as opposed to the specific image file) exists somewhere on the page.
Assertion or Verification?
Choosing between “assert” and “verify” comes down to convenience and management of failures. There’s very little point checking that the first paragraph on the page is the correct one if your test has already failed when checking that the browser is displaying the expected page. If you’re not on the correct page, you’ll probably want to abort your Workflow so that you can investigate the cause and fix the issue(s) promptly. On the other hand, you may want to check many attributes of a page without aborting the Workflow on the first failure as this will allow you to review all failures on the page and take the appropriate action. Effectively an “assert” will fail the test and abort the current Workflow, whereas a “verify” will fail the test and continue to run the Workflow.
The best use of this feature is to logically group your test commands, and start each group with an “assert” followed by one or more “verify” test commands. An example follows:
The above example first opens a page and then “asserts” that the correct page is loaded by comparing the title with the expected value. Only if this passes will the following command run and “verify” that the text is present in the expected location. The Workflow then “asserts” the first column in the second row of the first table contains the expected value, and only if this passed will the remaining cells in that row be “verified”.
verifyTextPresent
The command verifyTextPresent
is used to verify specific text exists somewhere on the page. It takes a single argument–the text pattern to be verified. For example:
Command | Target | Value |
---|---|---|
verifyTextPresent | Marketing Analysis |
This would cause AP to search for, and verify, that the text string “Marketing Analysis” appears somewhere on the page currently being tested. Use verifyTextPresent
when you are interested in only the text itself being present on the page. Do not use this when you also need to test where the text occurs on the page.
verifyElementPresent
Use this command when you must test for the presence of a specific UI element, rather than its content. This verification does not check the text, only the HTML tag. One common use is to check for the presence of an image.
Command | Target | Value |
---|---|---|
verifyElementPresent | //div/p/img |
This command verifies that an image, specified by the existence of an <img> HTML tag, is present on the page, and that it follows a <div> tag and a <p> tag. The first (and only) parameter is a locator for telling the command how to find the element. Locators are explained in the next section.
verifyElementPresent
can be used to check the existence of any HTML tag within the page. You can check the existence of links, paragraphs, divisions <div>, etc. Here are a few more examples.
Command | Target | Value |
---|---|---|
verifyElementPresent | //div/p | |
verifyElementPresent | //div/a | |
verifyElementPresent | id=Login | |
verifyElementPresent | link=Go to Marketing Research | |
verifyElementPresent | //a[2] | |
verifyElementPresent | //head/title |
These examples illustrate the variety of ways a UI element may be tested. Again, locators are explained in the next section.
verifyText
Use verifyText
when both the text and its UI element must be tested. verifyText
must use a locator. If you choose an XPath or DOM locator, you can verify that specific text appears at a specific location on the page relative to other UI components on the page.
Command | Target | Value |
---|---|---|
verifyText | //table/tr/td/div/p | This is my text and it occurs right after the div inside the table. |
Locating Elements
For many AP commands, a target is required. This target identifies an element in the content of the web application, and consists of the location strategy followed by the location in the format locatorType=location
. The locator type can be omitted in many cases. The various locator types are explained below with examples for each.
Locating by Identifier
This is probably the most common method of locating elements and is the catch-all default when no recognized locator type is used. With this strategy, the first element with the id attribute value matching the location will be used. If no element has a matching id attribute, then the first element with a name attribute matching the location will be used.
For instance, your page source could have id and name attributes as follows:
1 2 3 4 5 6 7 8 9 |
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
</form>
</body>
<html>
|
The following locator strategies would return the elements from the HTML snippet above indicated by line number:
identifier=loginForm
(3)identifier=password
(5)identifier=continue
(6)continue
(6)
Since the identifier
type of locator is the default, the identifier=
in the first three examples above is not necessary.
Locating by Id
This type of locator is more limited than the identifier locator type, but also more explicit. Use this when you know an element’s id attribute.
1 2 3 4 5 6 7 8 9 10 |
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
|
id=loginForm
(3)
Locating by Name
The name locator type will locate the first element with a matching name attribute. If multiple elements have the same value for a name attribute, then you can use filters to further refine your location strategy. The default filter type is value (matching the value attribute).
1 2 3 4 5 6 7 8 9 10 |
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
|
name=username
(4)name=continue value=Clear
(7)name=continue Clear
(7)name=continue type=button
(7)
Note
Unlike some types of XPath and DOM locators, the three types of locators above allow to test a UI element independent of its location on the page. So if the page structure and organization is altered, the test will still pass. You may or may not want to also test whether the page structure changes. In the case where web designers frequently alter the page, but its functionality must be regression tested, testing via id and name attributes, or really via any HTML property, becomes very important.
Locating by XPath
XPath is the language used for locating nodes in an XML document. As HTML can be an implementation of XML (XHTML), users can leverage this powerful language to target elements in their web applications. XPath extends beyond (as well as supporting) the simple methods of locating by id or name attributes, and opens up all sorts of new possibilities such as locating the third checkbox on the page.
One of the main reasons for using XPath is when you don’t have a suitable id or name attribute for the element you wish to locate. You can use XPath to either locate the element in absolute terms (not advised), or relative to an element that does have an id or name attribute. XPath locators can also be used to specify elements via attributes other than id and name.
Absolute XPaths contain the location of all elements from the root (html) and as a result are likely to fail with only the slightest adjustment to the application. By finding a nearby element with an id or name attribute (ideally a parent element) you can locate your target element based on the relationship. This is much less likely to change and can make your tests more robust.
Since only xpath
locators start with “//”, it is not necessary to include the xpath=
label when specifying an XPath locator.

<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
|
xpath=/html/body/form[1]
(3) - Absolute path (would break if the HTML was changed only slightly)//form[1]
(3) - First form element in the HTMLxpath=//form[@id='loginForm']
(3) - The form element with attribute named ‘id’ and the value ‘loginForm’xpath=//form[input/@name='username']
(3) - First form element with an input child element with attribute named ‘name’ and the value ‘username’//input[@name='username']
(4) - First input element with attribute named ‘name’ and the value ‘username’//form[@id='loginForm']/input[1]
(4) - First input child element of the form element with attribute named ‘id’ and the value ‘loginForm’//input[@name='continue'][@type='button']
(7) - Input with attribute named ‘name’ and the value ‘continue’ and attribute named ‘type’ and the value ‘button’//form[@id='loginForm']/input[4]
(7) - Fourth input child element of the form element with attribute named ‘id’ and value ‘loginForm’
These examples cover some basics, but in order to learn more, the following references are recommended:
There are also a couple of very useful Firefox Add-ons that can assist in discovering the XPath of an element:
- XPath Checker - suggests XPath and can be used to test XPath results.
- Firebug - XPath suggestions are just one of the many powerful features of this very useful add-on.
Locating Hyperlinks by Link Text
This is a simple method of locating a hyperlink in your web page by using the text of the link. If two links with the same text are present, then the first match will be used.
1 2 3 4 5 6 7 |
<html>
<body>
<p>Are you sure you want to do this?</p>
<a href="continue.html">Continue</a>
<a href="cancel.html">Cancel</a>
</body>
<html>
|
link=Continue
(4)link=Cancel
(5)
Locating by DOM
The Document Object Model represents an HTML document and can be accessed using JavaScript. This location strategy takes JavaScript that evaluates to an element on the page, which can be simply the element’s location using the hierarchical dotted notation.
Since only dom
locators start with “document”, it is not necessary to include the dom=
label when specifying a DOM locator.
1 2 3 4 5 6 7 8 9 10 |
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
|
dom=document.getElementById('loginForm')
(3)dom=document.forms['loginForm']
(3)dom=document.forms[0]
(3)document.forms[0].username
(4)document.forms[0].elements['username']
(4)document.forms[0].elements[0]
(4)document.forms[0].elements[3]
(7)
You can use AP itself as well as other sites and extensions to explore the DOM of your web application. A good reference exists on W3Schools.
Locating by CSS
CSS (Cascading Style Sheets) is a language for describing the rendering of HTML and XML documents. CSS uses Selectors for binding style properties to elements in the document. These Selectors can be used by AP as another locating strategy.
1 2 3 4 5 6 7 8 9 10 |
<html>
<body>
<form id="loginForm">
<input class="required" name="username" type="text" />
<input class="required passfield" name="password" type="password" />
<input name="continue" type="submit" value="Login" />
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
|
css=form#loginForm
(3)css=input[name="username"]
(4)css=input.required[type="text"]
(4)css=input.passfield
(5)css=#loginForm input[type="button"]
(7)css=#loginForm input:nth-child(2)
(5)
For more information about CSS Selectors, the best place to go is the W3C publication. You’ll find additional references there.
Note
Most experienced AP users recommend CSS as their locating strategy of choice as it’s considerably faster than XPath and can find the most complicated objects in an intrinsic HTML document.
Implicit Locators
You can choose to omit the locator type in the following situations:
- Locators without an explicitly defined locator strategy will default to using the identifier locator strategy.
- Locators starting with “//” will use the XPath locator strategy.
- Locators starting with “document” will use the DOM locator strategy.
Matching Text Patterns
Like locators, patterns are a type of parameter frequently required by commands. Examples of commands which require patterns are verifyTextPresent, verifyTitle, verifyAlert, assertConfirmation, verifyText, and verifyPrompt. And as has been mentioned above, link locators can utilize a pattern. Patterns allow you to describe, via the use of special characters, what text is expected rather than having to specify that text exactly.
There are three types of patterns: globbing, regular expressions, and exact.
Globbing Patterns
Most people are familiar with globbing as it is utilized in filename expansion at a DOS or Unix/Linux command line such as ls *.c
. In this case, globbing is used to display all the files ending with a .c
extension that exist in the current directory. Globbing is fairly limited. Only two special characters are supported in the AP implementation:
* which translates to “match anything,” i.e., nothing, a single character, or many characters.
[ ] (character class) which translates to “match any single character found inside the square brackets.” A dash (hyphen) can be used as a shorthand to specify a range of characters (which are contiguous in the ASCII character set). A few examples will make the functionality of a character class clear:
[aeiou]
matches any lowercase vowel
[0-9]
matches any digit
[a-zA-Z0-9]
matches any alphanumeric character
In most other contexts, globbing includes a third special character, the ?. However, AP globbing patterns only support the asterisk and character class.
To specify a globbing pattern parameter for a command, you can prefix the pattern with a glob: label. However, because globbing patterns are the default, you can also omit the label and specify just the pattern itself.
Below is an example of two commands that use globbing patterns. The actual link text on the page being tested was “Film/Television Department”; by using a pattern rather than the exact text, the click command will work even if the link text is changed to “Film & Television Department” or “Film and Television Department”. The glob pattern’s asterisk will match “anything or nothing” between the word “Film” and the word “Television”.
Command | Target | Value |
---|---|---|
click | link=glob:Film*Television Department | |
verifyTitle | glob:*Film*Television* |
The actual title of the page reached by clicking on the link was “De Anza Film And Television Department - Menu”. By using a pattern rather than the exact text, the verifyTitle
will pass as long as the two words “Film” and “Television” appear (in that order) anywhere in the page’s title. For example, if the page’s owner should shorten the title to just “Film & Television Department,” the test would still pass. Using a pattern for both a link and a simple test that the link worked (such as the verifyTitle
above does) can greatly reduce the maintenance for such Workflows.
Regular Expression Patterns
Regular expression patterns are the most powerful of the three types of patterns that supported. Regular expressions are also supported by most high-level programming languages, many text editors, and a host of tools, including the Linux/Unix command-line utilities grep, sed, and awk. Regular expression patterns allow a user to perform many tasks that would be very difficult otherwise. For example, suppose your test needed to ensure that a particular table cell contained nothing but a number. regexp: [0-9]+
is a simple pattern that will match a decimal number of any length.
Whereas globbing patterns support only the * and [ ] (character class) features, regular expression patterns offer the same wide array of special characters that exist in JavaScript. Below are a subset of those special characters:
PATTERN | MATCH |
---|---|
. | any single character |
[ ] | character class: any single character that appears inside the brackets |
* | quantifier: 0 or more of the preceding character (or group) |
+ | quantifier: 1 or more of the preceding character (or group) |
? | quantifier: 0 or 1 of the preceding character (or group) |
{1,5} | quantifier: 1 through 5 of the preceding character (or group) |
| | alternation: the character/group on the left or the character/group on the right |
( ) | grouping: often used with alternation and/or quantifier |
Regular expression patterns need to be prefixed with either regexp:
or regexpi:
. The former is case-sensitive; the latter is case-insensitive.
A few examples will help clarify how regular expression patterns can be used with commands. The first one uses what is probably the most commonly used regular expression pattern–.* (“dot star”). This two-character sequence can be translated as “0 or more occurrences of any character” or more simply, “anything or nothing.” It is the equivalent of the one-character globbing pattern * (a single asterisk).
Command | Target | Value |
---|---|---|
click | link=regexp:Film.*Television Department | |
verifyTitle | regexp:.*Film.*Television.* |
The example above is functionally equivalent to the earlier example that used globbing patterns for this same test. The only differences are the prefix (regexp: instead of glob:) and the “anything or nothing” pattern (.* instead of just *).
The more complex example below tests that the Yahoo! Weather page for Anchorage, Alaska contains info on the sunrise time:
Command | Target | Value |
---|---|---|
open | http://weather.yahoo.com/forecast/USAK0012.html | |
verifyTextPresent | regexp:Sunrise: *[0-9]{1,2}:[0-9]{2} [ap]m |
Let’s examine the regular expression above one part at a time:
Sunrise: * |
The string Sunrise: followed by 0 or more spaces |
[0-9]{1,2} |
1 or 2 digits (for the hour of the day) |
: |
The character : (no special characters involved) |
[0-9]{2} |
2 digits (for the minutes) followed by a space |
[ap]m |
“a” or “p” followed by “m” (am or pm) |
Exact Patterns
The exact type of AP pattern is of marginal usefulness. It uses no special characters at all. So, if you needed to look for an actual asterisk character (which is special for both globbing and regular expression patterns), the exact pattern would be one way to do that. For example, if you wanted to select an item labeled “Real *” from a dropdown, the following code might work or it might not. The asterisk in the glob:Real *
pattern will match anything or nothing. So, if there was an earlier select option labeled “Real Numbers,” it would be the option selected rather than the “Real *” option.
select | //select | glob:Real * |
In order to ensure that the “Real *” item would be selected, the exact:
prefix could be used to create an exact pattern as shown below:
select | //select | exact:Real * |
But the same effect could be achieved via escaping the asterisk in a regular expression pattern:
select | //select | regexp:Real \* |
It’s rather unlikely that most testers will ever need to look for an asterisk or a set of square brackets with characters inside them (the character class for globbing patterns). Thus, globbing patterns and regular expression patterns are sufficient for the vast majority of us.
The “AndWait” Commands
The difference between a command and its AndWait alternative is that the regular command (e.g. click) will do the action and continue with the following command as fast as it can, while the AndWait alternative (e.g. clickAndWait) tells AP to wait for the page to load after the action has been done.
The AndWait alternative is always used when the action causes the browser to navigate to another page or reload the present one.
Be aware, if you use an AndWait command for an action that does not trigger a navigation/refresh, your test will fail. This happens because AP will reach the AndWait’s timeout without seeing any navigation or refresh being made, causing AP to raise a timeout exception.
The waitFor Commands in AJAX applications
In AJAX driven web applications, data is retrieved from server without refreshing the page. Using andWait commands will not work as the page is not actually refreshed. Pausing the test execution for a certain period of time is also not a good approach as web element might appear later or earlier than the stipulated period depending on the system’s responsiveness, load or other uncontrolled factors of the moment, leading to test failures. The best approach would be to wait for the needed element in a dynamic period and then continue the execution as soon as the element is found.
This is done using waitFor commands, as waitForElementPresent or waitForVisible, which wait dynamically, checking for the desired condition every second and continuing to the next command in the script as soon as the condition is met.
Store Commands and Variables
You can use variables to store constants at the beginning of a script. Also, when combined with a data-driven test design (discussed in a later section), variables can be used to store values passed to your test program from the command-line, from another program, or from a file.
The plain store command is the most basic of the many store commands and can be used to simply store a constant value in a variable. It takes two parameters, the text value to be stored and a variable. Use the standard variable naming conventions of only alphanumeric characters when choosing a name for your variable.
Command | Target | Value |
---|---|---|
store | paul@mysite.org | userName |
Later in your script, you’ll want to use the stored value of your variable. To access the value of a variable, enclose the variable in curly brackets ({}) and precede it with a dollar sign like this.
Command | Target | Value |
---|---|---|
verifyText | //div/p | ${userName} |
A common use of variables is for storing input for an input field.
Command | Target | Value |
---|---|---|
type | id=login | ${userName} |
Variables can be used in either the first or second parameter and are interpreted by prior to any other operations performed by the command. A variable may also be used within a locator expression.
An equivalent store command exists for each verify and assert command. Here are a couple more commonly used store commands.
storeElementPresent
This corresponds to verifyElementPresent. It simply stores a boolean value–”true” or “false”–depending on whether the UI element is found.
storeText
StoreText corresponds to verifyText. It uses a locater to identify specific page text. The text, if found, is stored in the variable. StoreText can be used to extract text from the page being tested.
storeEval
This command takes a script as its first parameter. Embedding JavaScript is covered in the next section. StoreEval allows the test to store the result of running the script in a variable.
JavaScript and Parameters
JavaScript can be used with two types of parameters: script and non-script (usually expressions). In most cases, you’ll want to access and/or manipulate a Workflow variable inside the JavaScript snippet used as a parameter. All variables created in your Workflow are stored in a JavaScript associative array. An associative array has string indexes rather than sequential numeric indexes. The associative array containing your Workflow’s variables is named storedVars. Whenever you wish to access or manipulate a variable within a JavaScript snippet, you must refer to it as storedVars[‘yourVariableName’].
JavaScript Usage with Script Parameters
Several commands specify a script parameter including assertEval, verifyEval, storeEval, and waitForEval. These parameters require no special syntax. A AuraPlayer IDE user would simply place a snippet of JavaScript code into the appropriate field, normally the Target field (because a script parameter is normally the first or only parameter).
The example below illustrates how a JavaScript snippet can be used to perform a simple numerical calculation:
Command | Target | Value |
---|---|---|
store | 10 | hits |
storeXpathCount | //blockquote | blockquotes |
storeEval | storedVars[‘hits’]-storedVars[‘blockquotes’] | paragraphs |
This next example illustrates how a JavaScript snippet can include calls to methods, in this case the JavaScript String object’s toUpperCase
method and toLowerCase
method.
Command | Target | Value |
---|---|---|
store | Edith Wharton | name |
storeEval | storedVars[‘name’].toUpperCase() | uc |
storeEval | storedVars[‘name’].toLowerCase() | lc |
JavaScript Usage with Non-Script Parameters
JavaScript can also be used to help generate values for parameters, even when the parameter is not specified to be of type script. However, in this case, special syntax is required–the entire parameter value must be prefixed by javascript{
with a trailing }
, which encloses the JavaScript snippet, as in javascript{*yourCodeHere*}
. Below is an example in which the type
command’s second parameter value
is generated via JavaScript code using this special syntax:
Command | Target | Value |
---|---|---|
store | league of nations | searchString |
type | q | javascript{storedVars[‘searchString’].toUpperCase()} |
echo - The AP Print Command
Commands has a simple command that allows you to print text to your test’s output. This is useful for providing informational progress notes in your test which display on the console as your test is running. These notes also can be used to provide context within your test result reports, which can be useful for finding where a defect exists on a page in the event your test finds a problem. Finally, echo statements can be used to print the contents of variables.
Breakpoints and Startpoints
The Sel-IDE supports the setting of breakpoints and the ability to start and stop the running of a Workflow, from any point within the Workflow. That is, one can run up to a specific command in the middle of the Workflow and inspect how it behaves at that point. To do this, set a breakpoint on the command just before the one to be examined.
To set a breakpoint, select a command, right-click, and from the context menu select Toggle Breakpoint. Then click the Run button to run your Workflow from the beginning up to the breakpoint.
It is also sometimes useful to run a Workflow from somewhere in the middle to the end of the Workflow or up to a breakpoint that follows the starting point. For example, suppose your Workflow first logs into the website and then performs a series of tests and you are trying to debug one of those tests. However, you only need to login once, but you need to keep rerunning your tests as you are developing them. You can login once, then run your Workflow from a startpoint placed after the login portion of your Workflow. That will prevent you from having to manually logout each time you rerun your Workflow.
To set a startpoint, select a command, right-click, and from the context menu select Set/Clear Start Point. Then click the Run button to execute the Workflow beginning at that startpoint.
Stepping Through a Workflow
To execute a Workflow one command at a time (“step through” it), follow these steps:
- Start the Workflow running with the Run button from the toolbar.
- Immediately pause the executing Workflow with the Pause button.
- Repeatedly select the Step button.
Page Source for Debugging
Often, when debugging a Workflow, you simply must look at the page source (the HTML for the webpage you’re trying to test) to determine a problem. Firefox makes this easy. Simply right-click the webpage and select ‘View->Page Source. The HTML opens in a separate window. Use its Search feature (Edit=>Find) to search for a keyword to find the HTML for the UI element you’re trying to test.
Alternatively, select just that portion of the webpage for which you want to see the source. Then right-click the webpage and select View Selection Source. In this case, the separate HTML window will contain just a small amount of source, with highlighting on the portion representing your selection.
Locator Assistance
Whenever AuraPlayer IDE records a locator-type argument, it stores additional information which allows the user to view other possible locator-type arguments that could be used instead. This feature can be very useful for learning more about locators, and is often needed to help one build a different type of locator than the type that was recorded.
This locator assistance is presented on the AuraPlayer IDE window as a drop-down list accessible at the right end of the Target field (only when the Target field contains a recorded locator-type argument). Below is a snapshot showing the contents of this drop-down for one command. Note that the first column of the drop-down provides alternative locators, whereas the second column indicates the type of each alternative.
