Question

To listen to events during a test, which class has to be extended?

(a) org.junit.runner.notification.RunListener

(b) org.junit.runner.Listener

(c) org.junit.runner.notification.Listener

(d) org.junit.runner.RunListener

The question was posed to me by my college professor while I was bunking the class.

This interesting question is from JUnit Test Runners topic in portion Exploring Core JUnit of JUnit

Answer 1

Right option is (a) org.junit.runner.notification.RunListener

The explanation is: To respond to events during a test run, RunListener is extended and the appropriate methods overridden. If a listener throws an exception during a test event, it is removed for the remainder of the test run.
