Moq Cheat Sheet

// Create a stub
var mock = new Mock<IMyDependency>();

// Get the Stub
var myDep = mock.Object;

Assert.That(myDep .GetValue(), Is.EqualTo(0));

// Create a spy
var mock = new Mock<IMyDependency>();

// Spy on executions
mock.Verify(myDep => myDep.GetValue());

// Create a spy
var mock = new Mock<IMyDependency>();

    .Callback<String>(arg => usedArg = arg);{{nl}}
// Executing with "test" argument

    .Setup(myDep => myDep.GetValue())

    .Returns(1);{{nl}}
// Using the object
