Using should.deep.equal doesn't handle proimise rejection

[moar55]

chai-as-promised: v7.1.1
node: v8.9.4

When I do something as such: doSomethingAsync().should.eventually.deep.eql(8) an error is asserted normally if 8 is a wrong value. However, if i write doSomethingAsync().should.eventually.deep.equal(8) no erroneous assertion occurs and node displays an unhandled promise rejection warning.

Your situation is unclear based on what you wrote. Got some code to share?
Are you properly returning the promise at the end of your test, e.g.
return doSomethingAsync().should.eventually.deep.equal(8)?
