expect(500) passes if statusCode is undefined

[Izhaki]

Was just using this library to write a test.

Being TDD, I wrote the test first and was expecting the code to return 500.

But the code was never written and actually threw so statusCode was not defined.

The test passed.

Don't think 500 === undefined is correct. I believe expect should fail in that case.

Any example project / code snippet ?
