Review Comment:
Can this be done in the JUnit 4 or 5 style?

> Affects Versions: 4.4

> In COLLECTIONS-802 an issue reported was found with the help of Google Guava
> testlib tests.
> Maybe we could either have something similar (i.e. build ourselves?), use
> Google Guava's testlib, or find another similar solution. From what I
> understood, it uses a factory function to create an implementation of a
> collection interface (e.g. Map) and then runs a series of functional tests
> over the created object, failing tests if a contract is broken (e.g.
> iterating a map doesn't leave the next-object as null, as it was the case of
> the 802 issue).
