Class TestDebugger

java.lang.Object
  org.junit.rules.TestWatcher
      org.xwiki.test.ui.TestDebugger

All Implemented Interfaces:

org.junit.rules.TestRule

public class TestDebugger
extends org.junit.rules.TestWatcher

Generates debugging information on test failure:

• captures a screenshot of the browser window
• logs the URL of the current page
• logs the source of the current page

NOTE: The reason we also log when a test starts and passes is simply to overcome a deficiency in error reporting in Jenkins. The reason is that Jenkins bases its test reporting on the Maven Surefire plugin reporting which itself is using a file to report test status. Since ui-tests are using a test suite, PageObjectSuite, there's only a single file generated and it's only generated when all tests have finished executing. Thus if a test hangs there won't be any file generated and looking at the Jenkins UI it won't be possible to see which tests have executed.

Normally each JUnit Test Runner knows what test is executing and when it's finished and thus can report them in its own console (as this is the case for IDEs for example). Again the issue here is that Jenkins doesn't have any JUnit Test Runner but instead is calling JUnit by delegation to the Maven Surefire plugin.
