Screencast

http://www.wocommunity.org/podcasts/WOWODCW09-TDD.mov - 1 hour plus session on Test Driven Development with WebObjects presented by Denis Frolov on WOWODC 09. Shows how to use ERSelenium, jUnit, and Mockito with WebObjects.

Quick Start

• Checkout the Project Wonder - the ERSelenium is in the Wonder/CommonFrameworks/Frameworks Misc folder.
• Examine test cases from Wonder/Examples/Misc/ERSeleniumExample/Resources/Selenium/main/ and from BugTracker in Eclipse text editor.
• Launch ERSeleniumExample and point your browser (preferably FireFox - there are known issues with Safari) to SeleniumStartTesting Direct Action url (e.g. http://localhost/cgi-bin/WebObjects/ERSeleniumExample.woa/-42422/wa/SeleniumStartTesting).
• or Launch BugTracker and point your browser to SeleniumStartTesting Direct Action url (e.g. http://192.168.0.58localhost/cgi-bin/WebObjects/ERSeleniumExampleBugTracker.woa/-42422/wa/SeleniumStartTesting).

You can also use Selenium IDE to create and edit tests:

• Launch FireFox and install Selenium IDE Firefox plugin.
• Using Selenium IDE format plugin installation instructions install Selenese-ide-plugin.js (it is in ERSelenium/Resources).

  Tip
  title Opening Tests in Selenium IDE
  You need to select Selenese in the Options -> Format submenu before the Selenium IDE will allow you to open tests in the Selenese format

• Play around with test cases from ERSeleniumExample/Resources/Selenium/ using Selenium IDE.

Overview and Usage Notes

ERSelenium provides several features for effective use of SeleniumCore with WebObjects applications including:

• Custom setup/teardown actions that can be run before/after each test.
• Base URL independence.
• Support of HTML and Selenese test formats (Java support is planned).
• "On-the-fly" generation of test suites from the files in your project's source tree.
• Bookmarkable DirectAction url to run all tests (can be used for automated testing).
• Metacommands (special instructions specified in comments).

SeleniumCore is the powerful javascript toolkit for web applications "black-box" testing. It emulates different kinds of user actions such as: clicking the hyperlink, editing text in the input field, choosing item from the list and so on. See also: Selenium

Adding the ERSelenium

...

framework dependency to an Application

You can add a ERSelenium test runner component framework dependency to your application with eclipseEclipse/WOLips:

1. Add the ERSelenium.framework to your project's workspace Libraries dependency. See the tutorial: Add a Framework Dependency
2. (Optionally. Disabled by default. Use with caution). Enable the framework in the project's Properties fileSelenium tests direct action url in production mode via the property:

   Code Block
   SeleniumTestsEnabled=true

   Debug output of ERSelenium can be enabled in Properties by:

   Code Block
   log4j.logger.er.selenium = DEBUG

...

To run all tests point your browser to SeleniumStartTesting Direct Action:
http://baseurl/wa/SeleniumStartTesting

Example:
http://127.0.0.1localhost/cgi-bin/WebObjects/SampleProject.woa/-42421/wa/SeleniumStartTesting

To run a specific group of tests, add "/TestGroupName":

http://baseurl/wa/SeleniumStartTesting/TestGroupName
http://127.0.0.1/cgi-bin/WebObjects/SampleProject.woa/-42421/wa/SeleniumStartTesting/registration

Some tips for writing tests for ERSelenium

• Don't use full URLs with open/openWindow commands (http://baseurl part will be added by ERSelenium):

  Code Block
  |open|/wa/EditPerson| |open|/|

• You can use setup/teardown methods. They should be implemented as direct actions in the separate class, which should be er.selenium.SeleniumAction-descendant. SeleniumAction class has some handy helper methods and automatically turns your selenium-related actions off when selenium is disabled in Properties. Here's the example of using selenium-related direct actions in the test (suppose that resetSessionAction() is defined in the class "Selenium"):

  Code Block
  |open|/wa/Selenium/resetSession|

• You can use @repeat-@values-@done metacommands to execute specific part of the test with additional values edited in textboxes, e.g.:

  Code Block
  @repeat ...some actions... @values user1 user2 user3 |type|user|user0| @values pass1 pass2 pass3 |type|password|pass0| ...some more actions... @done

  The commands between @repeat and @done will be repeated several times, each time with new value in "user" and "password" input field. The values are seperated by spaces and if you have multiple @values lines, they all must have the same number of parameters. The @values section applies to the value of the next command.

...

• Selenium IDE Firefox plugin and XPath Checker can be very handy for creating and editing Selenium tests. Selenium IDE Selenese source plugin with proper comments support resides in ERSelenium/Resources/selenese-ide-plugin.js.

Using basic flow control

ERSelenium comes with a preinstalled flowControl user-contributed extension that provides some basic flow control. You can use its commands as described in the flowControl documentation.

For example, consider a test page that displays an integer counter (in the format "Counter = n", where n is the current value of the counter), and has an "Increment" button with id="increment". The following Selenese fragment would repeatedly press the button until the counter reached 10:

|while|!selenium.isTextPresent("Counter = 10");||
|click|increment||
|endWhile|||

Standalone runner

ERSelenium offers tests' developers several nice features - like automatic test suite generation, metacommands and URL independence. Unfortunately this leads to some troubles when trying to execute your tests with Selenium-RC. This is where StandaloneRunner can be very helpful.
