When creating unit tests to be run with NUnit, I like to keep my tests in a separate assembly, which is not delivered when my project is deployed.
This can make it difficult to create unit tests for classes that should not be visible outside of that assembly. One of my classes uses one of 3 strategy classes that encapsulate a feature of the business logic. I would normally declare these with the intern access modifier, but to test each strategy works I've needed to make them publically available.
If, however, I add the [assembly: InternalsVisibleTo("UnitTests")] line to my AssemblyInfo.cs file, any objects declared with the intern access modifier can be seen by the UnitTests assembly.
