Static class/method/property in unit test, stop it or not

Question

Answer 1

You can't mock static methods/properties. So, when your classA uses some static member of classB you can't test classA in isolation.

UPDATE: I don't see any problem of wrapping some static class into object. It doesn't take lot of time, but it allows you to decrease coupling in your system.
