While writing unit tests there can be certain scenarios where we need to verify that an exception is being thrown by the program during execution. TestNG provides a feature to test such scenarios by allowing the user to specify the type of exceptions that are expected to be thrown by a test method during execution. It supports multiple values being provided for verification. If the exception thrown by the test is not part of the user entered list, the test method will be marked as failed.
Let's create a sample test and learn how exception test works in TestNG.
