Description copied from interface: RetryStrategy

Handle an exception that occurred during the annotated test attempt.

This method can swallow the exception to pass the test.

Parameters:

testName - the test name

attemptIndex - test attempt index that starts from 1

throwable - the throwable that the test case throws

Throws:

org.opentest4j.TestAbortedException - When handling a test attempt failure, throwing this exception indicates another attempt should be made.

Throwable - Propagating the original exception, or throwing any other exception indicates that the test has definitively failed and no further attempts should be made.
