How to test if a method was called using nmock3?

Question

I'm trying trying to set the expectation that a method will be called. But when I write the lambda expresion inside the Method method, I get an error because I'm not passing the parameters. I don't care about the instance of the parameters, I only want to know if the method was called. Like the "It.IsAny" from Moq

What should I do?

The C# code: unitMock.Expects.One.Method(m=>m.Convert());

Answer 1

I don't know if this question is still actual. In any case, try to give any parameters to Convert method (just stubs) and add WithAnyArguments.

unitMock.Expects.One.Method(m=>m.Convert("")).WithAnyArguments();

Answer 2

If you want to put the method call exactly a number of times:

unitMock.Expects.Exactly (2) .Method (m => m.Convert ());

At the end you need to call:

_mockFactory.VerifyAllExpectationsHaveBeenMet ();

To make sure that if you call 2 times and not just 0 or 1.

If you want to establish exactly what data you should call the method:

unitMock.Expects.One.MethodWith (m => m.Convert ("5"));

If you want to establish what the method should return:

unitMock.Expects.One.MethodWith (m => m.Convert ("5")) WillReturn (5);
