Test doubles are objects that replace the dependent-on-component (DOC) in a test context so that the system under test gets an API as the real DOC and can perform activities against the API thinking that it is a real one!!!
There are different variations in the type of test doubles depending on the intent and context of usage. Ref: Test double patterns at XUnitPatterns.com.
In this post I’ll demonstrate the usage of the four main test doubles (Dummy, Fake, Stub and Mock) in the context of Microsoft Fakes and scenarios on how they can be implemented in your projects to
enhance code coverage. All the definitions for the patterns are copied from Gerard Meszaros XUnitPatterns catalog.
Dummy: A dummy is an object that is passed as a method argument or used as an attribute in a test context but never actually used. Usually they are just used to fill parameter lists.
var dummyCustomer = new StubCustomer();
var sut = new Invoice(dummyCustomer);
var book = new Product("XUnitPatterns");
var actual = sut.GetAllLineItems();
Assert.IsTrue(actual.Count() == 1);
