Mocking new Microsoft Entity Framework Identity UserManager and RoleManager

Question

Has anyone come up with a successful mocking solution for UserManager and RoleManager? I have been beating my head against a wall all day. All I wa

Answer 1

You won't be able to Mock UserManager or RoleManager directly. What you CAN do, however, is mock an object that uses them.

For Example:

public interface IWrapUserManager
{
    UserManager WrappedUserManager {get; set;}
    //provide methods / properties that wrap up all UserManager methods / props.
}

public class WrapUserManager : IWrapUserManager
{
    UserManager WrappedUserManager {get; set;}
    //implementation here. to test UserManager, just wrap all methods / props.
}

//Here's a class that's actually going to use it.
public class ClassToTest
{
    private IWrapUserManager _manager;
    public ClassToTest(IWrapUserManager manager)
    {
        _manager = manager;
    }
    //more implementation here
}

On to the mocking:

[TestClass]
public class TestMock
{
    [TestMethod]
    public void TestMockingUserManager()
    {
        var mock = new Mock();
        //setup your mock with methods and return stuff here.
        var testClass = new ClassToTest(mock.Object); //you are now mocking your class that wraps up UserManager.
        //test your class with a mocked out UserManager here.
    }
}
