Automate a test case in Microsoft Test Manager

To automate a test case, link it to a coded test method. You can link any unit test, coded UI test, or generic test to a test case. You’ll want to link a test method that performs the test described by the test case. Typically these are integration tests.

The results of automated and manual tests appear together. If the test cases are linked to backlog items, stories, or other requirements, you can review the test results by requirement.

  1. Link test cases to test methods

  2. Set the test plan to use your build

  3. Create a lab environment and settings to run the tests

  4. Run automated tests

  5. View and analyze the test results

You can make links one at a time, or you can generate test cases from an assembly of test classes.

  1. Using Visual Studio, create or choose a test method. It can be an ordinary test method, a coded UI test, ordered test, or a generic test method.

    Check the method into Team Foundation Server.

    Keep the solution open in Visual Studio.

  2. Open the test case in Visual Studio.

    Open Test Case Using Microsoft Visual Studio
  3. Associate the test method with your test case.

    Associate Automation With Test Case

    If you want to change or delete the association later, choose Remove Association.

We don’t recommend linking load tests or web tests to test cases.

  1. Open a Developer Command Prompt, and change directory to the output director of your Visual Studio solution.

    cd MySolution\MyProject\bin\Debug

  2. To import all the test methods from the solution:

    tcm testcase /collection: CollectionUrl /teamproject:MyProject /import /storage:MyAssembly.dll /category:"MyIntegrationTestCategory"

    The category parameter is optional but recommended. You only want to create test cases from integration or system tests, which you can mark by using the [TestCategory ("category")] attribute.

  3. In the Test hub in Team Web Access or in Microsoft Test Manager, use Add Existing to add the test cases to a test suite.

Provide the build location so that the test method can be found.

  1. In Microsoft Test Manager, choose Testing Center, Plan, Properties.

  2. Under Builds, set Filter for builds. You can set the build definition and quality attribute of the builds you want to choose from.

  3. Choose Modify to assign a build to the test plan. You can compare your current build with a build you plan to take. The associated items list shows the changes to work items between the builds. You can then assign the latest build to take and use for testing with this plan. For more information, see What development has been done since a previous build?.

I’m not using Team Foundation Build to build my application and tests. How can I run automated lab tests?

Create a build definition that contains just the location where your assemblies are shared. Then create a fake instance of this build from the developer command prompt:

TfsCreateBuild.exe /collection:http://tfsservername:8080/tfs/collectionname /project: projectname /builddefinition:"MyBuildDefinition" /buildnumber:"FakeBuild_1.0"

Specify the build definition in your test plan.

To run your automated tests tests using Microsoft Test Manager, you must use a lab environment. It must have roles for each of the client and server machines used in your tests. (If you’ve used lab environments for manual tests, notice that automated tests must have a machine for the client role.)

  1. Create or choose either a standard lab environment or an SCVMM lab environment.

    If you create a new environment, choose a machine for each role.

    The machines tab in the new environment wizard.

    If you’re planning to run coded UI tests, configure it on the Advanced page of the wizard. This sets the test agent to run as a user. You have to supply a user name under which the agent will run.

    We recommend that you use a different user account than the lab service account used by the test controller.

    The advanced tab in the new environment wizard.

  2. Set the test plan to use your environment for automated tests.

  3. If you want to collect more than the basic diagnostic data from the test machines, create a test settings file.

    New test settings

    In the test settings wizard, choose the data you want to collect for each machine.

    Select diagnostics for each machine role

Start automated tests the same way you do manual tests.

In Microsoft Test Manager, choose Testing Center, Test. Then select a test suite or an individual test and choose Run.

If you want to run a test in a different environment or with different test settings, choose Run with Options.

If you want to run an automated test manually, choose Run with Options.

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.

  1. In Microsoft Test Manager, choose Testing Center, Test, Analyze Test Runs.

  2. Double-click a test run to open it and view the details. You can:

    • Update the title of the test run to reflect the outcome.

    • Choose Resolution to indicate a reason, if the test failed.

    • Add comments.

    • View the details of an individual test.

    • Create a bug.

Q: Can I generate the test method from a manual run of the test case?

A: Yes. Verifying Code by Using UI Automation

Q: Can I automate deploying the code to a lab environment?

Yes. Automated build-deploy-test workflows

Q: I want my automated test to repeat with different data. Do I use the same test parameters that the manual version of the test case uses?

A: To make the automated test iterate over different data, write that into the code of the test method.

Test parameters are only used with the manual version of the test. They aren’t visible to the automated test code.
