I can't test code that has dbcontext.SomeEntity.SingleOrDefault() about nsubstitute HOT 2 CLOSED

There are a lot of problems with this code. NSubstitute is mainly designed to mock interfaces. So it is best to hide your DbContext behind access interfaces.

You can use NSubstitute for classes, but then you must really know what you are doing. You can only mock virtual methods/properties and you cannot use any extension methods.

To make a long story short, you are much better with writing tests against the DbContext with the in memory database.

I will look at just using a real db. I will create and destroy it with each test using the dbcontext. Might be slow, but should work.
