Weird error thrown

[ghost]

I have this code in a test:

person.isInState("Mood").should.be.true

The test is passing. But when I change the returned value by person.isInState("Mood") to false I get the following errors:

It doesn't make much sense. It comes from the runner.

i think i've seen this a few times now too, i'll check it out tomorrow

[ghost]

Some info:

Those errors occur when the tests are throwing errors (eg. the lib I am using).

The original error thrown is: [TypeError: Object # has no method 'inState']

But somehow the Mocha runner throws the above [TypeError: Cannot set property 'failed' of undefined] errors as a response.

[tj]

hmm i cant seem to reproduce this now

[ghost]

Try this:

it "should enter states serially", (done) ->
    methodDoesntExit()
    done()

It throws the errors I mentioned above.

[tj]

ah ok got it, it's when async

[tj]

ahahaha that tricky little bugger.. i got it

[marty-wang]

I ran into same issues several times. It is definitely async issue, and the solution I found is that you need to call assertions within the callback, either after done.

Here is my gist, https://gist.github.com/1392471

I just wasn't returning on the exception so it executed twice

[ghost]

Is the error 1 and 2 supposed to be there?

[tj]

hmm i think that might be due to the timer

[tj]

yup, reproduced it

[ghost]

Should/could this also be fixed? It might confuse the users.

[tj]

of course
