Unit tests for code accessing ActiveDirectory

Question

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 DirectorySear

Answer 1

If they're not mockable (don't have MSDN at hand, so I can't really tell), you can always abstract them behind an IDirectorySearcher and IDirectoryEntry and mock these. With this approach you can simplify the API by tailoring it specifically to suit your needs.

Answer 2

Is there no other possibility to use a leightweight directory server (ldap) like java developers do with Apache DS (http://directory.apache.org) in .NET?!

This would be a nice alternative.
