not in assertions is ignored

[iensu]

Given the following assertion:

expect(fromJS({ x: 1})).to.not.have.key('y');

I get the following result:

AssertionError: expected 'Map { "x": 1 }' to have key 'y'

So it seems that the not statement in the assertion is ignored.

I am using:

mocha 2.4.5
chai 3.5.0
chai-immutable: 1.5.4

Well that's interesting. Have you noticed this behavior with other assertions of the plugin?

I need to investigate, but if confirmed, I'm surprised the test suite didn't catch this, really.

Hi again!

Yes, I had a look at the test suite and it seems it should be covered, so I did some further investigation and it seems that it is https://github.com/prodatakey/dirty-chai that's the culprit here. Turning it off resolves the issue.

Thanks a lot for your time, I'm going to close this issue.

As a side note, I managed to get chai-immutable and dirty-chai working together by loading immutable-chai before loading dirty-chai

Hey @iensu, thanks for closing the loop!
That makes sense, there is similar requirement when using chai-immutable along with chai-as-promised.

I'm going to update the documentation to reflect that and will ping you so that you can proof-read.
