Walkthrough: Playing Back Coded UI Tests Using Firefox

  • Artikel

You can create automated tests of the user interface (UI) known as coded UI tests. These tests provide functional testing of the UI and validation of UI controls. Coded UI tests let you test the functionality of user interface Using the Microsoft Visual Studio 2010 Feature Pack 2, you can record UI actions on a website or on a Web-based application and create coded UI tests. You can use Windows Internet Explorer to record the actions and then play back the tests using the Mozilla Firefox browser.

For more information about coded UI tests, see Testing the User Interface with Automated UI Tests.

Warning

After you have completed the installation of Microsoft Visual Studio 2010 Feature Pack 2, if you want to use the Test Package for Mozilla Firefox, you must install and configure the Test Helper Extension for Mozilla Firefox. For more information, see How to: Install the Test Helper Extension for Mozilla Firefox.

Warning

You can use only the Firefox browser to play back the coded UI tests. Recording coded UI tests on websites and Web applications by using the Firefox browser is not supported.

Prerequisites

For this walkthrough you will need:

  • Visual Studio 2010 Ultimate, Visual Studio 2010 Premium or Test Professional 2010.

  • Mozilla Firefox Web browser version 3.5 or 3.6.

  • Verify that you have installed Microsoft Visual Studio 2010 Feature Pack 2 and the Test Helper Extension for Mozilla Firefox. Information about installation is included in the introduction.

Creating a Web Application

To create the Web application

  1. InVisual Studio 2010, on the File menu, click New and then click Project.

    The New Project dialog box appears.

  2. Under Installed templates, expand the programming language that you prefer and then click Web.

  3. In the list of Web project types, select ASP.NET Empty Web Application.

  11. In the Name text box, type Default.aspx and then click Add.

Adding Controls to the Web Application

To add controls to the Web application

  1. In Solution Explorer, right-click Default.aspx and choose View Designer.

    A blank page is displayed.

  2. If the toolbox is not visible click View and then click Toolbox.

  3. From the Standard group, drag a RadioButtonList onto the page.

    A RadioButtonList control is added to the design surface.

  8. Under ListItem properties change the Text property to Blue.

  9. Click OK to close the ListItem Collection Editor.

  10. Drag a Button onto the page. In the Properties window, change the Text property to Submit.

    ColorWebApp Design

  11. On the File menu, click Save All.

Adding Pages to the Web Application

To add pages to the Web application

  1. On the Project menu, click Add New Item.

  2. In the Add New Item dialog box, select Web Form from the list of templates. In Name type Red.aspx, and then click Add.

  3. At the bottom of the document window, click the Design tab to switch to design view.

  4. Drag a Label onto the page. In the Properties window, set the Text property to Red. Set the ForeColor property to Red.

  8. Drag a Label onto the page. In the Properties window, set the Text property to Blue. Set the ForeColor property to Blue.

  9. On the File menu, click Save All.

Adding Functionality to the Web Application

To add functionality to the Web application

  1. In Solution Explorer right-click Default.aspx and click View Designer.

  2. Double-click the Submit Button. Visual Studio switches to the page code, and creates a skeleton event handler for the Button control's Click event.

  3. Add the following code to the event handler:

    if (this.RadioButtonList1.SelectedValue == "Blue")
{
    Response.Redirect("Blue.aspx");
}
else
{
    Response.Redirect("Red.aspx");
}

    If RadioButtonList1.SelectedValue = "Blue" Then
    Response.Redirect("Blue.aspx")
Else
    Response.Redirect("Red.aspx")
End If

  4. On the File menu, click Save All.

Verify the Web Application Runs Correctly

Warning

This procedure assumes that Microsoft Internet Explorer is set as your default Web browser.

To run the Web application

  1. In Solution Explorer, right-click Default.aspx and then click Set As Start Page.

  2. Press CTRL+F5 to run the Web application in the browser. You will see the first page.

  3. Click Red and then click Submit. If the application is working correctly, you will go to the page with the Label that says Red.

  4. Go back to the first page.

  5. Click Blue and then click Submit. If the application is working correctly, you will go to the page with the Label that says Blue.

  6. Copy the address of your Web application to the clipboard or a notepad file. For example, the address might look like this: https://localhost:<PortNumber>/ Default.aspx

  7. Close the browser.

Create and Run a Coded UI Test for the Web Application

To Create and Run a Coded UI Test

  1. In Solution Explorer, right-click the solution, click Add and then select New Project.

    The Add New Project dialog box appears.

  2. In the Installed Templates pane, expand either Visual C# or Visual Basic, and then select Test.

  3. In the middle pane, select the Test Project template.

  4. Click OK.

    In Solution Explorer, the new test project named TestProject1 is added to your solution and either the UnitTest1.cs or UnitTest1.vb file appears in the Code Editor. You can close the UnitTest1 file because it is not used in this walkthrough.

  5. In Solution Explorer, right-click TestProject1, click Add and then select Coded UI test.

    The Generate Code for Coded UI Test dialog box appears.

  6. Select the Record actions, edit UI map or add assertions option and click OK.

    The UIMap – Coded UI Test Builder appears.

    For more information about the options in the dialog box, see How to: Create a Coded UI Test.

  7. Click Start Recording on the UIMap – Coded UI Test Builder. In a few seconds, the Coded UI Test Builder will be ready.

    Start recording UI

  8. Launch Internet Explorer.

  9. In Internet Explorer’s address bar, enter the address of the Web application that you copied in a previous procedure. For example:

    https://localhost:<PortNumber>/ Default.aspx

    (Optional) navigate through the Web application by pressing the Red, Blue and the browser’s back button.

  10. Close Internet Explorer.

  11. On the UIMap - Coded UI Test Builder, click Generate Code.

  12. In the Method Name type SimpleWebAppTest and click Add and Generate. In a few seconds, the Coded UI test appears and is added to the Solution.

    Generate code

  13. Close the UIMap – Coded UI Test Builder.

    The CodedUITest1.cs file appears in the Code Editor.

Confirm the Coded UI Test Plays Back Properly in Internet Explorer

  • In the CodedUITest1.cs file, locate the CodedUITestMethod1 method, right-click and select Run Tests.

    While the coded UI test runs, the ColorWebApp is visible. It conducts the steps that you did in the previous procedure.

Add a Property to SpecifyFirefox Playback and Rerun the Coded UI Test

  1. In the CodedUITest1.cs file, locate the MyTestInitialize() method which uses the TestInitializeAttribute uncomment the code and add the CurrentBrowser property with its value assigned as “FireFox” as shown in the following code:

    Tip

    Optionally, instead of adding the BrowserWindow property, you can create an environment variable called CodedUITestCurrentBrowser that has a value of “Firefox” and then restart Visual Studio.

    ////Use TestInitialize to run code before running each test 
        [TestInitialize()]
        public void MyTestInitialize()
        {        
        //    // To generate code for this test, select "Generate Code for Coded UI Test" from the shortcut menu and select one of the menu items.
        //    // For more information on generated code, see https://go.microsoft.com/fwlink/?LinkId=179463
            BrowserWindow.CurrentBrowser = "Firefox";
        }

    ' Use TestInitialize to run code before running each test
    <TestInitialize()> Public Sub MyTestInitialize()
        '
        ' To generate code for this test, select "Generate Code for Coded UI Test" from the shortcut menu and select one of the menu items.
        ' For more information on generated code, see https://go.microsoft.com/fwlink/?LinkId=179463
        '
        BrowserWindow.CurrentBrowser = "Firefox"


    End Sub

    For more information about using the TestInitialze() attribute, see How to: Generate a Coded UI Test by Recording the Application Under Test.

  2. On the Test menu, select Windows and then click Test View.In Test View, select CodedUITestMethod1 under the Test Name column and then click Run Selection in the toolbar.

    The coded UI test should run using Mozilla Firefox.
