1. To generate an ASP.NET unit test, start by creating an ASP.NET Web site. To do this, right-click your solution, point to Add, and then click New Web Site.

2. On the Add New Web Site dialog box, click ASP.NET Web Site.

3. Under Location, click File System to indicate ASP.NET Development Server.

4. Click OK.

   You now have a new Web site.

5. Add a class to this project. To do this, in Solution Explorer, right-click the Web site and then click Add New Item.

6. In the Add New Item dialog box, click Class, and then click Add.

7. A Microsoft Visual Studio dialog box is displayed to ask about placing the new class in the App_Code folder. Click Yes.

   Note:
   You cannot generate tests from code in an .aspx file or in a folder other than the App_Code folder.

8. Generate an ASP.NET unit test. If the new class file is not already open, double-click it in Solution Explorer to open it.

9. Right-click the class in the class file, and then click Create Unit Tests.

10. The Create Unit Tests dialog box appears. For information about how to use this dialog box to generate unit tests, see How to: Create and Run a Unit Test.

11. Verify that the classes, methods, or namespaces for which you want to generate tests are selected.

12. (Optional) Accept the default Output project or select a new project.

13. When you are finished, click OK.

    The new ASP.NET unit test is added to a file in your test project.

    To see the unit test, open the test file and scroll to the end. The attributes that are necessary to run a unit test as an ASP.NET unit test have been automatically specified. For more information about these attributes, see the following procedure, Configuring an ASP.NET Unit Test.

1. Open the code file that contains the unit test.

2. Set the following attributes for the unit test:

[TestMethod]

Because all unit tests require the [TestMethod] attribute, this attribute will already be in place.

[UrlToTest()]

This is the URL that is tested when this unit test is run; for example, [UrlToTest(“http://localhost/WebSites/Default.aspx”)]

[HostType()]

Use [HostType(“ASP.NET”)]. Tests are typically run under the VSTest host process, but ASP.NET unit tests must run under the ASP.NET host process.

Examples

Example 1. If you are running your Web site with the ASP.NET Development Server, the attributes and values you set for an ASP.NET unit test might resemble the following:

[TestMethod()]

[HostType("ASP.NET")]

[UrlToTest("http://localhost:25153/WebSite1")]

[AspNetDevelopmentServerHost("D:\\Documents and Settings\\user name\\My Documents\\Visual Studio 2005\\WebSites\\WebSite1", "/WebSite1")]

Example 2. To test a Web site running under IIS, use only the attributes TestMethod, HostType, and UrlToTest:

[TestMethod()]

[HostType("ASP.NET")]

[UrlToTest("http://localhost:25153/WebSite1")]

1. Open a run configuration file. For more information, see How to: Specify a Test Run Configuration.

2. On the Hosts page, set the Host Type to ASP.NET.

   This displays additional choices, some of which correspond to attributes you can specify in code, such as Url to Test. These attributes are described in the previous procedure, "Configuring an ASP.NET Unit Test."

   When you have finished setting the values on the Hosts page, click Save and then click OK.
