listener annotation in testng
Listener annotation is used in selenium to generate logs or customize the
TestNG reports.
We have to add first <listeners> class-name="Listener"/> tag into our
testng.xml file. Then create a Listener class which implements ITestListener
interface and override all the abstract methods from there.
The Listener class can be under any folder however Utilities package is
more proper to store it.
ITestListener has methods like:
- onStart- OnStart method is called when any Test starts.
- onTestSuccess- onTestSuccess method is called on the success of any Test.
- onTestFailure- onTestFailure method is called on the failure of any Test.
- onTestSkipped- onTestSkipped method is called on skipped of any Test.
- onTestFailedButWithinSuccessPercentage- method is called each time Test fails
but is within success percentage.
- onFinish- onFinish method is called after all Tests are executed
