Create some tests that act as a contract for all Platforms (PlatformLaws)

[isnotinvain]

Writing the tests for SparkLaws lead me to think that there should really be a platform agnostic set of laws, or at least a PlatformLaws base class. There's a lot of overlap with the scalding platform in these tests. Having a PlatformLaws test suite would also better describe the contract and expected behavior of all platforms.

Anybody working on that? I would like to try do that.
For now that test should be base for ScaldingLaws, StormLaws and SparkLaws. Am I correct?
Should I use specs2?

Great! Noone's working on this, afaik. We also have MemoryLaws and ConcurrentMemoryLaws. I believe we prefer using scalatest now, @johnynek please advise.

I'm not sure but we might need two base sets of laws, laws for online and laws for offline

If ScalaTest should it be 2.2.2 version? I noticed val with version in Build.scala but no dependency.
