Unit test for a specific exception message | Java

17.08.2022

I used to use AssertJ in unit tests where I had to check for a specific exception message. My colleague recently found a simple way to do this with no extra dependencies, using a try/catch block.

@Test
public void sendGift_throwsException_whenGiftIsNuclearBomb() {
    try {
    	service.sendGift(new NuclearBomb());
    } catch (Exception e) {
    	assertEquals("Cannot send nuclear bomb as a gift", e.getMessage());
    }
}
