How to mock throw new customException?

Question

Hope all are doing good.

I am wanted to mock one of my exception which is inside one private method like below :

 private void verifyScenarios(String empid, String token) {
   if (Validation if true)  // Line 1 :
    throw new CustomException("my message"); //Line 2
   else
    any code.    
 }

Line 1: will be true. Line 2 : This line throwing exception because of that my junit test case is failing, Is there any way to mock line 2 and make it success.

Thanks in advance.

Such things are not possible with Mockito, however I believe that all you need is to assert (pass the test) if exception is thrown, because it is a part of your business logic.

Try @Test(expected = CustomException.class) instead of @Test if you are using JUnit 4. Test will pass only if code will throw your exception.

You can use an expected exception rule. With this solution you can easily check the error message that is thrown as well.
