Testing For Specific Properties Of Rejected Promises, With Mocha And Chai-as-promised

I am trying to test the specifics of a rejected Promise, using Chai-as-Promised, Mocha, and the 'should' dialect. Promises are implemented by bluebird. This works fine: it('it shou

Solution 1:

I think rejectedWith() handler has some issues. But you can do like this:

promiseOfUsers.should.be.rejected.and.eventually.have.property("status",401)

Solution 2:

If you want to check if your promised was rejected and check the resulting object (aka the reason):

return fooPromise.should.be.rejected.and.eventually.deep.equal({
   'x': 1,
   'y': 1,
   'z': 2
})

You can change deep.equal to the any of the usual other chaimatchers.

Note: This is an extension of @sertug's answer and hopefully will be useful for others coming here who looking for this.
