For your information, there have been improvements on the TFS  and SVN front - see this:

I have asked a question on that may be relevant to testing the repository classes, in particular to using the same test suite on different repository implementations.
The answers may illuminate how we go about testing interfaces:

SVN support is very cool and I guess will make it even easier for people to check-out the source. I've also been impressed with Visual Studio Team Explorer.

great post on stackoverflow!  I like the base class option personally.
Sep 18, 2008 at 9:27 AM
I'm thinking of using the base class option to put some tests on all providers,
and if need be option 1 to put some tests against only some of the providers.

+1 for the base class option :-)

Done. Now we need to write some substantial tests, and to make them pass.
And maybe set up some File-based providers (and file data for them) to feed to the same tests

Can you explain the need for the type enum?  I think we can avoid it. So, as an example I added a categories test which uses a base constructor to set the repository with less code.

The RepositoryType enum can be thought of as the "mode" of the tests, or a flag to tell the tests how to operate.
I'm sure that it can be done without the enum, but the enum seemed to me the simplest way to do it.
The stack overflow answers mention it:

You could create the test class with a new repository, but there are lifecycle issues - with the File or SQL repository, you sometimes want to test that the data has been persisted - e.g. create a repository object, save data using it, then create a new repository object (in the same test), and try to load the same data back.

With the mock repository, you can see that the GetRepository() method creates one Repository instance and returns it repeatedly. This is because there is no "back end", the data is stored in memory in the instance.

Another way to do it - perhaps the constructor could be given a "generator function" or anon delegate that creates repositories on demand.

Sounds like an abstract GetRepository method on the base class is all that is needed.  I could be trying to oversimplify things though.

That would actually work nicely - I didn't spot the simpler way. I will do it that way.
