If the database had not been ready when you started coding this portion of the user story, you could have used a mock object here instead. To do that, you would first add a reference to the NMock DLL (nmock.dll) to the TestLayer project. Next, you would create an interface class called IUserData.cs that looks like the following. #region Using directives using System; using System.Collections.Generic; using System.Text; using BusinessLayer; #endregion namespace DataLayer { interface IuserData { User GetUser(string username, string password); } } Then you would make the UserTests.cs class look like the following. #region Using directives using System; using System.Collections.Generic; using System.Text; using NUnit.Framework; using NMock; using BusinessLayer; using DataLayer; #endregion namespace TestLayer { [TestFixture] public class UserTests { public UserTests() { } [SetUp] public void Init() { }

If you run Listing 4-6, you will see a slider at the top of the screen. Initially it will be at the far left, representing a factor of 0 (fireball orange). If you click and drag toward the right of the screen, you can smoothly change the blending factor toward 1 (zombie green). The resulting color is displayed in the lower half of the screen. You can experiment with blending between other colors by changing the values of color1 and color2 at the top of the script. Try blending between completely contrasting colors and shades of similar colors.

[TearDown] public void Destroy() { } [Test] public void TestGetUser() { DynamicMock userData = new DynamicMock (typeof(IUserData)); Assert.IsNotNull(userData.GetUser("bogususer", "password"), "GetUser returned a null value, gasp!"); } } } When the database became available, you would implement the UserData.cs class as shown in Listing 13-2 and have the UserData class inherit (implement) the IUserData interface. At that time, you would also update the UserTests.cs class to use the UserData.cs class instead of the mock object you implemented.
