Don't know if you noticed this but there is a bug in behave.js from the codestrong site that means that async tests pass even though they have not executed their callback. I found the changing line 65 of behave.js to the following worked for me.

else if ((that.expectations.length === 0 && that.done) || (time > that.timeout|| time > 10000)) {

thx for the info

Great catch @sudsy!

Using @sudsy fix for me it doesn't work. I have some expectations that are not evaluated and test pass event.
