Title: Added sureOfFailure() for those of us who prefer failure to success

Added sureOfFailure()

Basically to help with unit testing. You can verify that an API fails as expected under certain conditions with a similarly short syntax to checking that it passes as expected.

Feel free to decline if it is against your tastes. But I thought if it's useful to me it might be useful to others.
