Unit Testing Mock/Stub definitions in Moq

Question

Any reading or advice I\'ve been given on Unit Testing has always suggested a distinct difference between the definition of a Mock and a Stub. My current understanding of these

Answer 1

Indeed, Moq can create true stubs. From the Moq Quick Start page:

* Setup a property so that it will automatically start tracking its value (also known as Stub):

  // start "tracking" sets/gets to this property
  mock.SetupProperty(f => f.Name);

  // alternatively, provide a default value for the stubbed property
  mock.SetupProperty(f => f.Name, "foo");


  // Now you can do:

  IFoo foo = mock.Object;
  // Initial value was stored
  Assert.Equal("foo", foo.Name);

  // New value set which changes the initial value
  foo.Name = "bar";
  Assert.Equal("bar", foo.Name);

* Stub all properties on a mock (not available on Silverlight):

  mock.SetupAllProperties();

IMHO, the distinctions between flavors of fakes is best thought of as a distinction between functions of those fakes rather than types of fakes, as a fake may take on multiple roles at once (e.g. can be a true mock and a saboteur all at once), and as no such distinction is necessary for using a mock framework. (I should blog about this!)
