How to: Create Test Cases from an Assembly of Automated Tests Using tcm.exe

If you have created automated tests using Visual Studio, you might want to run these tests as part of a test plan. By adding them to a test plan, you can measure your testing progress. You can view the results from these automated tests and any other tests in your test plan together and track the progress that you are making. You can also link these test cases to requirements, so that you can view the status of automated tests for the requirement. For more information about how to do this, see Link Existing Test Cases to a Requirement.

To run these tests as part of a test plan, you can use a command line tool tcm.exe to create test cases for all your test methods in an assembly or some of your test methods based on test method properties or the test category. If you want to add a test to an existing test case, you can associate a test method directly with that test case. For more information, see How to: Associate an Automated Test with a Test Case.

Requirements

  • Visual Studio Ultimate, Visual Studio Premium, Visual Studio Test Professional

If you have existing automated tests from earlier versions of Visual Studio, you can associate these tests with a test case after you upgrade the test project that contains the automated tests to Visual Studio.

After you have imported your test methods and created test cases, you have to add these test cases into your test plan. To run these test cases from your test plans, you must use a lab environment. You cannot run automated tests using Microsoft Test Manager without an environment.

You must check in the test project that contains the automated test methods and make sure that the test project is part of your build definition. You must make sure that a build created by using this build definition is selected in your test plan. The information from the build is used by Microsoft Test Manager to locate the correct test method assembly and use this to run the automated tests.

For more information about how to check in your test project and team build, see How to: Add a Project or Solution to Version Control and Building the Application.

You can also run automated tests from the command line using test settings and a test environment. For more information, see How to: Run Automated Tests from the Command Line Using Tcm.

Use the following procedures to create test cases from an assembly of automated tests that you can then run as part of your test plan:

Parameter

Description

/collection:CollectionURL

Specifies the URI of the team project collection. The format for the URI is as follows: http://ServerName:Port/VirtualDirectoryName/CollectionName

If no virtual directory is used, then the format for the URI is the following:

http://ServerName:Port/CollectionName

If you do not know the correct path, contact your Team Foundation system administrator.

/teamproject: TeamProjectName

The team project that you want to use. This team project must be defined in the project collection that is specified by the /collection parameter.

/login: UserName,Password

Optional. Specifies the name and password of a user who is logged on to the application-tier server for Team Foundation Server and who has permissions to run the command.

You would use this option if your Windows credentials do not have the appropriate permissions, or you are using basic authentication, or you are not connected to a domain.

/? or help

Displays help about the command in the Command Prompt window.

To create test cases from an assembly of automated tests

  1. Open a Visual Studio command prompt.

    To do this, choose Start, point to All Programs, point to Microsoft Visual Studio 2012, point to Visual Studio Tools, and then choose Developer Command Prompt.

    The command prompt opens to the folder: <drive>:\Program Files\Microsoft Visual Studio 11.0\VC

  2. Change directory to the folder that contains the assembly built from your test project.

    To do this, first change directory to your solution folder. Then change directory to the folder for your test project by typing the following command at the command prompt:

    cd <project name> \bin\Debug

  3. To import all the test methods from your assembly, type the following at the command prompt:

    tcm testcase /collection:<CollectionURL> /teamproject: <Team Project name> /import /storage: <name of your assembly> .dll

    You will see results similar to these:

    Modification Title

    ---------------- ------------------

    Added <Name of test method>

    Added <Name of test method>

    Summary

    ------------

    Added 2

    Updated 0

    Total 2

    Note Note

    The test cases that are created will have the same names as the test methods that were imported.

  4. (Optional) You can limit the test methods that are imported from the assembly based on test categories. For more information about test categories, see Defining Test Categories to Group Your Tests. For example, the following command shows you how to import tests that are in both the ShoppingCart and SmokeTest categories.

    tcm testcase /collection:<CollectionURL> /teamproject: <Team Project name> /import /storage: <name of your assembly> .dll /category:"ShoppingCart&SmokeTest"

  5. (Optional) You can limit the test methods that are imported from the assembly based on a test method property. For example, the following command shows how to import all test methods that have priority set to 0 or 1.

    tcm testcase /collection:<CollectionURL> /teamproject: <Team Project name> /import /storage: <name of your assembly> .dll/maxpriority:1

  6. Open Microsoft Test Manager.
