ExpectedExceptions

The list of exceptions that a test method is expected to throw. If no exception or a different than one on this list is thrown, this test will be marked a failure.


Lets create java class

import org.testng.annotations.Test;
publicclass expectexception {
@Test//(expectedExceptions = ArithmeticException.class)
publicvoid divisionWithException() {
System.out.println("thrown expectedExceptions");
inti = 1 / 0;
}
}

If you run test case without expected Exceptions, it will throw an exception.
