[Task] Creating and managing tests: Create and manage both manual and automated tests as part of your plan. You can create test cases to be run as manual tests with individual test steps from Microsoft Test Manager. Automated tests, such as unit tests, load tests and automated UI tests, can be created by using Visual Studio. Later, if you want, you can convert test cases to automated tests by linking automation to the test case. [Related topics]
