Code Examples

Returns

Mock.Setup(context => StaticClass.MethodToMock(context.It.IsAny<int>()), () =>
{
    var actualResult = StaticClass.MethodToMock(1);
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Returns(expectedResult);

Mock.Setup(context => StaticClass.MethodToMock(context.It.IsAny<int>()), () =>
{
    var actualResult = StaticClass.MethodToMock(1);
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Returns(() => expectedResult);

Mock.Setup(context => StaticClass.MethodToMock(context.It.Is<int>(x => x == 1)), () =>
{
    var actualResult = StaticClass.MethodToMock(1);
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Returns<int>(argument => argument);

Mock.Setup(context => StaticClass.MethodToMockAsync(context.It.IsAny<int>()), async () =>
{
    var actualResult = await StaticClass.MethodToMockAsync(1);
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Returns<int>(async argument => await Task.FromResult(argument));

Callback

Mock.Setup(() => StaticClass.MethodToMock(), () =>
{
    var actualResult = StaticClass.MethodToMock();
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Callback(() =>
{
    DoSomething();
});

Mock.Setup(context => StaticClass.MethodToMock(context.It.IsAny<int>()), () =>
{
    var actualResult = StaticClass.MethodToMock(1);
    Assert.AreNotEqual(originalResult, actualResult);
    Assert.AreEqual(expectedResult, actualResult);
}).Callback<int>(argument =>
{
    DoSomething(argument);
});

SetupDefault

Mock.SetupDefault(() => StaticClass.VoidMethodToMock(), () =>
{
    StaticClass.VoidMethodToMock(); // This method do nothing
});
