How to: Associate an Automated Test with a Test Case

You might begin your testing cycle by creating a manual test case that you decide later is a good test to automate. You want to be able to continue to run that test as part of a test plan. Or you might have a manual test case that you used to create an action recording when you ran your test. Now you have created a coded UI test from that action recording and you want to associate this coded UI test with the original test case and run it as an automated test. For more information about action recordings and coded UI tests, see Recording and Playing Back Manual Tests and Testing the User Interface with Automated UI Tests.

You associate an automated test with a test case using Visual Studio. After you create your automated test, you must check in your test project that contains the automated test and make sure that the test project is part of your build definition. Then you associate the automated test with a test case that has been added to a test plan that uses this build. For more information about checking in your test project and team build, see Add Files to Version Control and Building the Application.

Important noteImportant

If you are not using Team Foundation Build to build your application and tests, you can still run automated tests using Microsoft Test Manager. You must create a build definition that just has a share location added that is where your assemblies for your tests are located.

Also, you might have created a set of automated tests that you want to run as part of a test plan using Microsoft Test Manager. You can import these automated tests from an assembly and create test cases associated with each test using a command line tool for Microsoft Test Manager. For more information about how to import automated tests, see How to: Create Test Cases from an Assembly of Automated Tests Using tcm.exe.

You can only associate the automated test with your test case using Visual Studio. You cannot make this association using Microsoft Test Manager. If you have an existing test case that you want to use, you must first open the test case using Visual Studio as shown in the following illustration.

Open Test Case Using Microsoft Visual Studio

Then you can associate the test method with your test case as shown in the following illustration.

Associate Automation With Test Case

If you need to create a new test case, then you can do this from the Test View window as described in the following procedure Create a Test Case From an Automated test. You must then add this test case to a test plan to be able to run it.

NoteNote

You can view the information from Microsoft Test Manager, but you cannot modify it.

The following table shows the types of automated tests that you can create and which types of tests can be run as part of a test plan:

Type of test

Description

Run from a test plan by associating a test method with a test case

Coded UI Tests

Tests the user interface by performing UI actions.

Yes

Unit Tests

Tests code at the method level.

Yes

Database Unit Tests

Tests a stored procedure, function or trigger in a database.

Yes

Load tests

Tests application performance and stress using unit tests, Web Performance tests or coded UI tests.

Not recommended because you cannot view the test as it runs.

Web Performance Tests

Used as part of load tests to test server responses for Web applications by sending and receiving http requests.

NoteNote
These tests cannot be used to test the UI.

Not recommended because Web Performance tests are primarily intended to be used with load tests.

Generic Tests

Test functionality using API calls or command line tools for the application under test.

Yes

Use the following procedures to associate an automated test with a test case that you can then run as part of your test plan:

The parameters in a test case are not used by any automated test that you associate with a test case. Iterations of a test case that use these parameters are for manual tests only.

To add the automated test to your test case

  1. To open the solution that contains the automated test, click File and point to Open and then click Project/Solution.

    The Open Project dialog box is displayed.

  2. Select your solution, and then click Open.

    NoteNote

    You must open your solution to be able to associate the automation with the test case.

  3. If you know the work item of the test case, in Team Explorer, on the Team menu, click Go To Work Item.

    You can also right-click the Work Items node for your team project.

  4. In the Go to Work Item dialog box, in the ID box, type the ID number of your test case.

  5. Click OK to open the work item.

    NoteNote

    You can also use a pre-existing query in the Team Queries or My Queries node to find the work item if you do not know the ID. For more information about how to use queries in Team Explorer, see Finding Bugs, Tasks, and Other Work Items.

  6. To add the automated test, click the Associated Automation tab.

  7. To find the automated test name, click the ellipsis (…).

    The Choose Test dialog box is displayed. All the tests in the solution are shown in the list together with their associated test projects.

    NoteNote

    If a test case already has an automated test associated with it, you must first remove this association before you can add a different automated test. Click Remove association to remove the existing automation.

  8. Select the test, and then click OK.

    NoteNote

    The value in Automation Status is automatically changed to Automated.

  9. To save the changes to the test case, click Save Work Item.

    The next part of the process is to set up your test plan to use your build.

To add the automated test to your test case

  1. To open the solution that contains the automated test, click File and point to Open and then click Project/Solution.

    The Open Project dialog box is displayed.

  2. Select your solution, and then click Open.

    NoteNote

    You must open your solution to be able to associate the automation with the test case.

  3. To open the Test View window, click Test, point to Windows, and then point to Test View.

    The Test View window is displayed.

  4. To create a new test case for the automated test, right-click the test method in the Test View window and point to Create Test Case from Test.

    The fields in the Associated Automation tab are automatically filled in for the test method that you selected in the Test View window.

    NoteNote

    The value in Automation Status is automatically changed to Automated.

  5. Type the name of the test case in Title.

  6. To set the priority of the test case, click Priority.

    NoteNote

    For more information about the fields in a test case, see How to: Create a Manual Test Case.

  7. To save the changes to the test case, click Save Work Item.

    You must add the test case to your test plan using Microsoft Test Manager. For more information, see How to: Add a Test Case to a Test Suite.

    The next part of the process is to set up your test plan to use your build.

To set up your test plan to run the automated test that you have created, you must select the correct build definition used to build your automated test or a build definition that has the correct build drop location for your existing automated test assemblies. You must do this so that the automated test can be found in the share location for your build definition and then it can be run from Microsoft Test Manager.

Important noteImportant

If you have multiple build configurations, the test assemblies to run the automated tests are searched for recursively from the root directory of the build drop folder. If it is important which assemblies are selected when you run your automated tests, you should use Run with options to specify the build configuration. For more information about how to do this, see How to: Override Settings in Your Test Plan For Test Runs.

To set up your test plan to use your team build

  1. Open Microsoft Test Manager.

    NoteNote

    To display the Microsoft Test Manager window, click Start, and then click All Programs. Point to Microsoft Visual Studio 2010 and then click Microsoft Test Manager 2010.
