Android JUnit Testing … How to Expect an Exception

Question

I\'m attempting to write some tests using the built-in android Junit testing framework. I am running into a problem with a test where I am expecting an exception to be thrown.

Answer 1

The standard junit 3 idiom for this sort of test was:

public void testThatMethodThrowsException()
{
  try
  {
    doSomethingThatShouldThrow();
    Assert.fail("Should have thrown Arithmetic exception");
  }
  catch(ArithmeticException e)
  {
    //success
  }
}
