MOQ验证执行无效

Question

I'm trying to mock my internal virtual method. When I debug I can see I get to where I expect and my internal virtual method is exceuted but the test fails. Further more, I verified 'this' context is the proxy and not a regular class instance.

Methods:

public void MyMethod() { MyInternalMethod() }
internal virtual void MyInternalMethod() {}

Piece of unit test:

Because of = () => { myMock.Object.MyMethod() };

It should_run_inner_internal_virtual_MyInternalMethod = () =>
{
              myMock.Verify(x => x.MyInternalMethod(),Times.Once());
};

I'll appreciate any help.

Kind regards.

Am not sure if your code compiles, but I think since Moq and the class under test are in different assemblies, you may need to tell the assembly of the object under test to make internal visible to the Moq's assembly. internal only makes a method / property / class visible to that assembly.

Try adding this to your AssemblyInfo.cs file (for the assembly under test)

[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")] 

assuming DynamicProxyGenAssembly2 is your Moq's assembly name. If your test is also in a different assembly, then you need to make the internals visible to that assembly as well. I just wrote a nunit test for this, and it passes.

[Test]
public void ShouldCallMyInternalMethodFromMyMethod()
{
  myMock = new Mock<MyClass>();
  myMock.Object.MyMethod();
  myMock.Verify(mockObj=> mockObj.MyInternalMethod(), Times.Once());
}
