We can run it parallel as well by setting attribute “parallel” value as true.

Why test cases are getting skipped in Testng?

The test cases get randomly skipped on some browser and platform. The probability of occurance of skip test cases increases with subsequent run of test suite. I believe the reason is that more and more driver instances that were not properly closed keep running in the back ground.

How can we skip test case conditionally?

Instead of checking the suite Run mode, check the Run mode of test case as Y/N in the @beforeTest Method. Then if you found the run mode as N, throw an exception . throw new skipException(“skipping test case as run mode is y”). This will skip your test case.
