Grails assert - verify that assertion failed in unit test

Question

Grails newbie question:

when you have assert [condition] in a Grails controller, how do you verify that the assertion fails from a unit test?

I'm thinking something like shouldFail(Exception) { .. } but I'm not sure what exception to catch.

Thanks

You can use AssertionError .

shouldFail(AssertionError) {
  assert 'one' == 'two'
}
