ShouldEqual does not compare time.Time correctly

[mdwhatcott]

@kofalt - Have you tried using ShouldResemble?

[kofalt]

I'm not certain that's the best solution for time - as an example of a failing test:

(Should resemble)!

The output & functionality would probably be more precise using time.Equal, since the time.Location struct field can have so much stuff on it. My guess is that it wouldn't work for comparing a time object that came from a Go source with a time object inflated from an external source.

That said, for my use case, ShouldResemble works well enough, and I'm not sure what sort of lines you want to draw about struct comparisons and the like. Feel free to close or leave open as desired 🙂

Yeah, comparing time values is annoying. I was hoping that ShouldResemble would work for your use case.

Your workaround (using ShouldHappenWithin is actually pretty nice (hadn't seen that approach before--thanks for sharing!). It's probably better than doing something like So(time.Equal(t1, t2), ShouldBeTrue).

I think I'll continue using workarounds until such time as oglematchers handles this for us.
