Before we get there, I want to cover one last piece of test initialization as provided in MSTest by the AssemblyInitializeand AssemblyCleanupattributes. KalamazooX When XUnit run a test method, it's going to create a new object of our test class for each and everyone of our test method. Safello Aktie Flashback, After I moved the QueryTestFixture to another project the Class attribute stopped working, Which was linked to the implementation in the fixture class (see below). It must have not be abstract. This is useful when that initialization or cleanup is expensive, such as creating a database connection, or loading several data files. return View(); Unlike their counterparts, TestInitializeand TestCleanup, methods decorated with these class-level attributes are executed just once per class, rather than once per test in the class. Already on GitHub? In the case of TestInitializeand TestCleanup, XUnit uses the test class constructor and IDisposable.
