#endregion namespace TestLayer { public class CategoryTests { public CategoryTests() { } } } 4. Right-click the TestLayer and select Add Reference. 5. In the Add Reference dialog box, click the Browse tab. Navigate to the NUnit applica- tion’s bin directory, which is located at C:\Program Files\NUnit 2.2.2\bin (if you installed NUnit in the default location). 6. Select the following DLLs: nunit.core.dll, nunit.extensions.dll, nunit.framework.dll, nunit.uikit.dll, nunit.util.dll, and nunit-gui-runner.dll. Then click the Open button. 7. Verify that the NUnit DLLs are listed in the Browse tab, as shown in Figure A-10, and then click the OK button. Figure A-10.

Change the code to look like this: #region Using directives; using System; using System.Collections.Generic; using System.Text; using NUnit.Framework; using BusinessLayer; #endregion namespace TestLayer { [TestFixture] public class CategoryTests { Category computerCategory; [SetUp] public void Init() { computerCategory = new Category(1, // Category ID "Computer", // Category Name "Computer related stuff."); // Category Description } [TearDown] public void Destroy() { computerCategory = null; } [Test] public void GetCategoryName() { string computerCategoryName = computerCategory.CategoryName; Assert.IsNotNull(computerCategoryName, "The category name was null, gasp!"); Assert.AreEqual("Computer", computerCategoryName, "Got the wrong category name, gasp!"); } } } 9. Add a C# file to the BusinessLayer project called Category.cs. APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT288 4800AppA.qrk 5/22/06 9:04 PM Page 288 10. Change the Category.cs file code to look like this: #region Using directives using System; using System.Collections.Generic; usinf System.Text; #endregion namespace BusinessLayer { public class Category { private int categoryID; private string categoryName; private string categoryDescription; public Category(int categoryID, string categoryName, string categoryDescription) { this.categoryID = categoryID; this.categoryName = categoryName; this.categoryDescription = categoryDescription; } public string CategoryName { get { return this.categoryName; } } } } 11. Right-click the TestLayer project and select Add Reference. 12. Click the Projects tab, select BusinessLayer from the list, and click the OK button. 13. Right-click the TestLayer project and select Set as StartUp Project. The TestLayer project name will now appear in bold. 14. Select Build ➤ Build Solution (or press Ctrl+Shift+B). 15. Select Debug ➤ Start (or press F5). This will bring up the NUnit window, as shown in Figure A-11.

If everything went correctly, you should see a green bar under the Run button, and the testing tree on the left should have all green circles, as shown in Figure A-12. Click the window’s close box to exit NUnit. Figure A-12. Results of running the test Don’t be worried if you don’t understand everything in the source code files you just created. Chapters 7, 13, and 15 explain how these files work. This example is very trivial and not optimized in any way. However, it does start to give you an idea of what a testing framework does. APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT290 4800AppA.qrk 5/22/06 9:04 PM Page 290 The Database Setup For this book’s examples, you also need to configure the Northwind database. This involves setting up the Open Database Connectivity (ODBC) data source and associating that data source with Visual Studio Solution Explorer. ■Note When deciding on the type of database to use in our examples, we went back and forth several times. We thought of using Microsoft SQL Server or the Microsoft SQL Server Database Engine (MSDE), but ended up using Microsoft Access because we could package the complete database in our source archive. You can find a copy of the Northwind.mdb file in the source code archive for this book at the Apress web- site (www.apress.com). Setting Up the ODBC Data Source First, you need to set up an ODBC data source that references the database. To configure an ODBC data source, follow these steps: 1. Extract and copy the Northwind.mdb database file to a local directory on your hard drive (for example, C:\xpnet\database\). ■Note In our examples, we are assuming that you are using Microsoft Windows XP. If you are not, then you will need to adjust these instructions accordingly. 2. Open Control Panel, select Administrative Tools, and launch the Data Sources (ODBC) application. You will see a dialog box similar to the one shown in Figure A-13. Figure A-13. The ODBC Data Source Administrator dialog box APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT 291 4800AppA.qrk 5/22/06 9:04 PM Page 291 3. Select the System DSN tab and click the Add button to open the Create New Data Source dialog box, as shown in Figure A-14. Figure A-14. The Create New Data Source dialog box 4. Select the Microsoft Access Driver and click the Finish button. 5. In the ODBC Microsoft Access dialog box, enter Northwind in the Data Source Name field, as shown in Figure A-15. Then click the Select button. Figure A-15. The ODBC Microsoft Access Setup dialog box 6. Enter the path to the location of your Northwind.mdb file and click OK. The ODBC Microsoft Access Setup dialog box will show your changes. Click OK to commit your changes. 7. The ODBC Data Source Administrator dialog box appears with the Northwind data source in the list. Click the OK button to close this dialog box. Connecting to the Database Now that you have an ODBC data source referencing the database, you can set up a new Visual Studio data connection. Follow these steps to connect to the Northwind database: APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT292 4800AppA.qrk 5/22/06 9:04 PM Page 292 1. Open the Northwind solution, and then open the Server Explorer, if it is not already visible. (Choose View ➤ Server Explorer or press Ctrl+Alt+S to display the Server Explorer.) 2. Right-click Data Connections in the Server Explorer and select Add Connection. 3. Click the Provider tab and select Microsoft OLE DB Provider for ODBC Drivers, as shown in Figure A-16. Figure A-16. Selecting the Microsoft OLE DB Provider for ODBC Drivers 4. Click the Connection tab and select Use Data Source Name. Select Northwind in the first drop-down list. Then click OK. If you expand the Data Connections node in the Server Explorer, you will see a connec- tion for ACCESS.C:\xpnet\database\northwind.admin. If you expand the Northwind database, you will see icons for Tables and Views, as shown in Figure A-17. These are parts of the Northwind database. Figure A-17. The Server Explorer with the new data connection APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT 293 4800AppA.qrk 5/22/06 9:04 PM Page 293 Browsing the Database Let’s take a quick look at the database itself. Follow these steps: 1. Open the Server Explorer and expand the ACCESS connection. You should now see new entries showing the Tables and Views nodes (see Figure A-17). 2. Expand the Tables node. A list of all the tables in the database will be displayed, as shown in Figure A-18. Figure A-18. Tables in the Northwind database 3. Right-click the Products table and select Retrieve Data from Table. This will retrieve all the data in the Products table in the Northwind database and display it in a spread- sheet form, as shown in Figure A-19. APPENDIX A ■ PREPARING YOUR DEVELOPMENT ENVIRONMENT294 4800AppA.qrk 5/22/06 9:04 PM Page 294 Figure A-19. The Products table You can add delete and change data directly from this form. You can also use this same process to view any table in the database. You now have set up your environment for the examples in this book. You created the appropriate Visual Studio solution and projects, configured NUnit, and finally configured your Microsoft Access data source, which holds the database that you will be using in the examples.
