If we are in test driven development, we need to spend significant amount of time in writing unit tests. In VSTS unit testing framework, every test run create a unique folder in our machine and generate a test report ( *.trx format) for every test run-
Sometimes it’s needed to access the folder that current test run created. UnitTestAdapterContext class provides a set of properties related to current test run that can be accessed from inside unit tests.
To use the properties provided in UnitTestAdapterContext class we need to – add the following properties in our Test Class –
private TestContext testContextInstance;
/// <summary>
///Gets or sets the test context which provides
///information about and functionality for the current test run.
///</summary>
public TestContext TestContext
{
get
{
return testContextInstance;
}
set
{
testContextInstance = value;
}
}
The property is automatically assigned by the test run engine of VSTS. Take a look at the properties and functionalities offered by TestContext –
If I start debugging a unit test adding a break point and watch the TestContext, we can view different information about and functionality for current test run -
So ,picece of cake - Current TestRun Directory can be accessed by just one line of code-
string testDirectory = TestContext.TestDir;
Therefore , we can use class in our TestContext Unit Tests to get different informations about the current test run and we can use different functioanallity of this class – for example – BeginTimer() and EndTimer() would be verify useful to measure our application’s differenent module’s performance to validate certain non-functional requirements.
