ClassInitialize and ClassCleanup: Since ClassInitialize and ClassCleanUp are static, they are only ex

9、ecuted once even though several instances of a test class can be created by MSTest. ClassInitialize executes in the instance of the test class corresponding to the first test method in the test class. Similarly, MSTest executes ClassCleanUp in the instance of the test class corresponding to the last

10、 test method in the test class.2. Execution Interleaving: Since each instance of the test class is instantiated separately on a different thread, there are no guarantees regarding the order of execution of unit tests in a single class, or across classes. The execution of tests may be interleaved acr

11、oss classes, and potentially even assemblies, depending on how you chose to execute your tests. The key thing here is all tests could be executed in any order, it is totally undefined.3. TextContext Instances: TestContexts are different for each test method, with no sharing between test methods. For

12、 example, if we have a Test Class: TestClass public class VSTSClass1 private TestContext testContextInstance; public TestContext TestContext get return testContextInstance; set testContextInstance = value; ClassInitialize public static void ClassSetup(TestContext a) Console.WriteLine(Class Setup); T

14、eanUp); ClassCleanup public static void ClassCleanUp() Console.WriteLine(ClassCleanUp); (This consists of 3 Test Methods, ClassInitialize, ClassCleanup, TestInitialize, TestCleanUp and anexplicit declaration of TestContext)The execution order would be as follows:Test1 Thread 1: new TestContext - Cla

15、ssInitialize - TestInitialize - TestMethod1 - TestCleanUpTest2 Thread 2: new TestContext - TestInitialize - TestMethod2 - TestCleanUpTest3 Thread 3: new TestContext - TestInitialize - TestMethod2 - TestCleanUp - ClassCleanUpThe output after running all the tests in the class would be:Class SetupTest
