Ques. How can we skip a test case conditionally?

Ans. Using SkipException, we can conditionally skip a test case. On throwing the skipException, the test method is marked as skipped in the test execution report and any statement after throwing the exception will not get executed.

@Test public void testMethod(){ if(conditionToCheckForSkippingTest) throw new SkipException("Skipping the test"); //test logic }
