Better testing for wrapped errors #1
Description
In my tests, I'd like to be able to assert that an error being returned from a function at least implements Causer. It would also be nice to verify where the call was actually wrapped from.
I'm wondering how that functionality might be added...
Semi-related, it seems that Expect(err1).To(MatchWrappedError(err2)) will fail if err1 is wrapped but err2 is a plain error... but isn't that rather pointless since MatchError() will fail in that case as well? Wouldn't it be more useful to verify that err1 is wrapping err2?
