Q2507. Can we pass the junit test if the tested method throws the exception ? and Should we do that ?

Junit

Ans. Yes, We can pass the test even if the tested method throws an exception.

One way is know as exception testing in which the tested method is expected to throw exception and hence the expectation is set accordingly.

@Test(expected = IndexOutOfBoundsException.class)
public void test(){}

Other way is to just ignore if the tested code throws an exception. In that case , we can enclose the tested method call in the try block and within exception block, we just return gracefully.

Exception testing is perfectly ok to be done as we would like test code in case an exception occurs and if the code is handling the exception properly. Ignoring the exception by putting the tested method call within try block isn't something normal and should be avoided.
