they must run a few more assert statements than what you see in the editor, so all visible test might pass but you may still have a bug in your code.

if you're positive your code works, there is also an unescaped ' in the last assert: this 'Seventh, forty - it's correct' should be 'Seventh, forty - it\'s correct'
