How do you handle AssertionError in selenium?

In the case of Hard Assertion, you can handle the error by using a catch block like a java exception. Suppose we have two test cases in a suite. The first test case in a suite has an assertion that fails, and if we want to run the second case in a suit, then we need to handle the assertion error.

How do you handle AssertionError in TestNG?

If you catch the AssertionError, TestNG can’t see it. Agreed, continuing the test after a failure is not best practice. Use after*Methods() for stuff. Specifically for logging of test (configuration) start and end however, don’t do it in the test class at all – create a listener, and do the logging from the listener.

Before we go any further it’s worth noting that, by default, assertions are disabled for most JVMs. Thus, executing code with a failing assertion will completely ignore the failure and will not throw an AssertionError.

How do I enable assertion checking in Java?

To enable assertion checking you’ll need to add a command-line switch: -enableassertions or -ea. For example, if you’re executing code via the java command line tool, you’d need to issue something like the following command: $ java -ea .
