Support inequality validation for post in tests #2227
Description
Right now, we support validation for an Account in post to have its storage set as some value, or its balance be some value. For values that alter the starting state but is maybe a hash or some undetermined value, or even for tests where we may just want to make sure this value is different, it would be nice to have some way to validate this. It has more recently come up in a couple of different contexts:
It would be nice to be able to support that some starting value has changed at post... or even perhaps that it doesn't equal some value. It's a bit slippery but with great power comes great responsibility (🕷️) and I think we could distinguish well enough when this is warranted and when it isn't. I can see the argument to not have this at all as well though.
