Tool for compatibility checking?

[Mike Schilling]

Does anyone know of a tool, preferably open source, for checking that
versions N and N+1 of a library are compatible? Ideally:

* The tool is open source
* It allows specifying which classes are to be checked, either by inclusion
or by exclusion
* Its result is a report listing any places where compatibility has been
violated, e.g. where a method was added to an interface

I assume that you mean a simple API support check and not a check
against implementation problems in the library.

No - I don't know of either, but it is two very different problems.

Yes. I don't see how to check the latter (run-time compatibility) other
than a complete set of unit tests.

Exactly.
