1.4. Example of ITestListener

ITestListener has methods on following events:

• onStart is invoked after the test class is instantiated and before any configuration method is called
• onTestSuccess is invoked on success of a test
• onTestFailure is invoked on failure of a test
• onTestSkipped is invoked whenever a test is skipped
• onTestFailedButWithinSuccessPercentage is invoked each time a method fails but is within the success percentage requested.
• onFinish is invoked after all the tests have run and all their Configuration methods have been called.

TestListenerExample is our test class. It has a @BeforeTest and an @AfterTest method. It has four test methods:

1. testcase1() is expected to run fine
2. testcase2() is expected to fail as it doesn’t throw the expected exception
3. testcase3() receives a parameter but since we haven’t set a DataProvider, it is skipped
4. testcase4() is invoked five times, of which, twice its going to fail. We have set the expected successPercentage to 50.
