SimpleMock 1.0.0

SimpleMock

SimpleMock is a very simple mocking framework, something that I have always wanted to try to write but I was prompted to have a go after a discussion at work.

Usage

The examples below use the following interface as an example

public interface IWorker
{
    int DoSomething(int anInt, string aString, bool aBool);
    string DoSomethingStringy(int anInt);
    int Height { get; }
}

Creating the Mock

var workerMock = new Mock<IWorker>();

Mocking a Method

workerMock
    .Setup(w => w.DoSomething(0, "", false))
    .Returns(5);

N.B. Currently the values supplied as parameters are ignored. In this example, any call to DoSomething will return 5.

Mocking a Readable Property

workerMock
    .Setup(w => w.Height)
    .Returns(10);

Supplying the Mock to a Dependant

var dependant = new Dependant(workerMock.MockObject);

Getting the Call Count

workerMock.GetCallCount(w => w.DoSomething(0, "", false));

N.B. Currently the values supplied as parameters are ignored. In this example, the call count will be the total number of calls to DoSomething regardless of parameters.

Getting the Parameter Values of a Specific Call

workerMock.GetCallParameters(w => w.DoSomething(0, "", false), 7);

N.B. The index is zero-based.

N.B. Currently the values supplied as parameters are ignored. In this example, the parameters will be those of the eighth call to DoSomething regardless of parameters.

Limitations

This is only a very simple and niave implementation so there are a number of limitations, amongst which are:

• Can only mock interfaces
• No support for callbacks
• Argument values passed in the Setup method are ignored.
• No verification on number of calls to mock.
