What’s the best way to unit test an application accessing the ActiveDirectory and/or mock the dependencies to the AD?
All the required types such as DirectorySearcher and DirectoryEntry don’t appear to be easily mockable.
We’ve got methods like FindByUserName() and would like to (unit) test them.
If they’re not mockable (don’t have MSDN at hand, so I can’t really tell), you can always abstract them behind an
IDirectorySearcherandIDirectoryEntryand mock these. With this approach you can simplify the API by tailoring it specifically to suit your needs.
