在使用EFProf（Entity Framework Profiler）进行单元测试中使用Effort的ASP Boilerplate问题

Question

Having issues using EFProf ( http://www.hibernatingrhinos.com/products/EFProf ) with ASP Boilerplate ( http://www.aspnetboilerplate.com/ ).

For unit testing, ASP Boilerplate uses Effort ( https://github.com/tamasflamich/effort ) for mocking the database in-memory.

If I run the unit tests without adding the reference to EFProf, the tests run correctly (green).

If I add the initialization line:

HibernatingRhinos.Profiler.Appender.EntityFramework.EntityFrameworkProfiler.Initialize();

in either my test base ctor or my application project's Initialize(), I get the following error:

Castle.MicroKernel.ComponentActivator.ComponentActivatorException

ComponentActivator: could not instantiate MyApp.EntityFramework.MyAppDataContext

The inner exception has the relevant information:

Error: Unable to cast object of type 'Effort.Provider.EffortConnection' to type 'HibernatingRhinos.Profiler.Appender.ProfiledDataAccess.ProfiledConnection'.

Is Effort just not compatible with EFProf? Or am I doing something blindingly obvious wrong in my initialization?

Answering my own question: Effort fakes the DbContect object but does not actually create SQL for in-memory, thus there is nothing to intercept by profilers. It is also the reason why the CommandText is always null when using EF6's Database.Log with Effort.

Am going to try using Moq with EF6 to use an in-memory database implementation for testing as an alternative to Asp Boilerplate's testing project that utilizes Effort per this article: https://msdn.microsoft.com/en-us/library/dn314429(v=vs.113).aspx
