2、tInitialize()属性表示测试初始化跑的地方TestCleanup()属性表示是每次执行完测试类后清除的东西也就是测试类最后跑的地方TestMethod1. ClassInitialize and ClassCleanup: Since ClassInitialize and ClassCleanUp are static, they are only executed once even though several instances of a test class can be created by MSTest. ClassInitialize executes in the
3、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 test method in the test class.2. Execution Interleaving: Since each instance of the test class is instantiated sepa
4、rately 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 across classes, and potentially even assemblies, depending on how you chose to execute your tests. The key thing here i
5、s 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 example, if we have a Test Class: TestClass public class VSTSClass1 private TestContext testContextInstance; public
6、 TestContext TestContext get return testContextInstance; set testContextInstance = value; ClassInitialize public static void ClassSetup(TestContext a) Console.WriteLine(Class Setup); TestInitialize public void TestInit() Console.WriteLine(Test Init); TestMethod public void Test1() Console.WriteLine(
7、Test1); TestMethod public void Test2() Console.WriteLine(Test2); TestMethod public void Test3() Console.WriteLine(Test3); TestCleanup public void TestCleanUp() Console.WriteLine(TestCleanUp); ClassCleanup public static void ClassCleanUp() Console.WriteLine(ClassCleanUp); (This consists of 3 Test Met
8、hods, ClassInitialize, ClassCleanup, TestInitialize, TestCleanUp and anexplicit declaration of TestContext)The execution order would be as follows:Test1 Thread 1: new TestContext - ClassInitialize - TestInitialize - TestMethod1 - TestCleanUpTest2 Thread 2: new TestContext - TestInitialize - TestMeth
9、od2 - TestCleanUpTest3 Thread 3: new TestContext - TestInitialize - TestMethod2 - TestCleanUp - ClassCleanUpThe output after running all the tests in the class would be:Class SetupTest InitTest1TestCleanUpTest InitTest2TestCleanUpTest InitTest3TestCleanUpClassCleanUpCase分类组织TestCategory分类，TestList中筛
10、选组织UnitTest文件TestMethod测试用例注意UnitTest文件和TestMethod的命名规范例子using System;using System.Text;using System.Collections.Generic;using System.Linq;using Microsoft.VisualStudio.TestTools.UnitTesting;using OpenQA.Selenium;using OpenQA.Selenium.Firefox;/*namespace TestProject1 TestClass public class UnitTest1
11、TestMethod public void TestMethod1() IWebDriver driver = new FirefoxDriver(); driver.Url = http:/localhost:8080/AltoroJ/; driver.FindElement(By.Id(LoginLink).Click(); driver.Quit(); */*namespace TestProject1 TestClass public class UnitTest1 IWebDriver driver; TestInitialize public void Setup() drive
12、r = new FirefoxDriver(); TestMethod public void TestMethod1() driver.Url = http:/localhost:8080/AltoroJ/; driver.FindElement(By.Id(LoginLink).Click(); TestMethod public void TestMethod2() driver.Url = http:/localhost:8080/AltoroJ/; driver.FindElement(By.Id(query).SendKeys(hello!); TestCleanup public void TearDown() driver.Quit(); */*namespace TestPro
