-- `CurrentTestOutcome` – the result of the current test.
-- `FullyQualifiedTestClassName` – the full name of the test class.
-- `TestRunDirectory` – the directory where the test run is executed.
-- `DeploymentDirectory` – the directory where the deployment items are located.

 In MSTest 3.7 and later, the `TestContext` class also provides new properties helpful for `TestInitialize` and `TestCleanup` methods:
 
-- `TestData` – the data that will be provided to the parameterized test method or `null` if the test is not parameterized.
-- `TestDisplayName` - the display name of the test method.
-- `TestException` - the exception thrown by either the test method or test initialize, or `null` if the test method did not throw an exception.
