I am trying to use the @Rule annotation with ExpectedException

The ExceptedException.none() method to initialize a variable type of ExceptedException says it has been deprecated what are the alternatives to initialize an object of the ExceptedException. Example:

public ExpectedException expectedException = ExpectedException.none();

@Test
public void testThrownException() throws Exception {
    expectedException.expect(CustomException.class);
    expectedException.expectMessage("Exception Message");
    ...
}

Did you read the deprecation notice?

Deprecated. Since 4.13 Assert.assertThrows can be used to verify that your code throws a specific exception.

  • Works great, thanks! I was so engrossed in looking for a workaround for this that I did not read the workings of **Assert.assertThrows**, the best being the flexibility to choose assertion framework and make assertions on the caught exception. – Prashant Kumar Singh Jun 13 '20 at 08:43

    The problem in my opinion is that the deprecation is done on the method `none()` but surely should be done on the class `ExpectedException`? I was looking for an alternative method of using `ExpectedException` but that's not the migration strategy. – mjaggard Mar 08 '21 at 15:51
