Understanding the MSTest TestContext

Question

Using MSTest, I needed to obtain the name of the current test from within the [TestInitialize] method. You can get this from the TestContext.TestName

Answer 1

Scenario: context for each test.

Applies to Visual Studio 2017 with the following libraries:

• Microsoft.VisualStudio.TestPlatform.TestFramework
• Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions

Sample code:

    [TestClass]
    public class MyTestClass
    {

        public TestContext TestContext { get; set; }

        /// 

        /// Run before each UnitTest to provide additional contextual information.
        /// TestContext reinitialized before each test, no need to clean up after each test.
        /// 
        [TestInitialize]
        public void SetupTest()
        {
            TestContext.Properties.Add("MyKey", "My value ...");

            switch (TestContext.TestName)
            {
                case "MyTestMethod2":
                    TestContext.Properties["MyKey2"] = "My value 2 ...";
                    break;
            }

        }

        [TestMethod]
        public void MyTestMethod()
        {
            // Usage:
            // TestContext.Properties["MyKey"].ToString()
        }   

        [TestMethod]
        public void MyTestMethod2()
        {
            // Usage:
            // TestContext.Properties["MyKey"].ToString()

            // also has:
            // TestContext.Properties["MyKey2"].ToString()
        }

    }
