Shit, I've been working for 10 years (but only a few months with these tools).

I actually considered the looser validation when I discovered that toHaveReceivedAnyCommand() worked, but, ultimately decided there *had* to be something wrong with my setup and I refused to leave it to hit someone else.

Shame the AWS SDK doesn't communicate the actual error in a more human readable way. I was legitimately questioning my sanity and/or the validity of the library for a minute there.
