ClassInitialize上的数据驱动单元测试

我试图每次用不同的值运行一些测试。例如:我有3种方法:methodA、methodB、methodC。我想用不同的索引位置运行每个方法两次。我有TestInitialize和ClassInitialize方法。

1. 我尝试使用ClassInitialize，但我没有成功;我得到编译时错误，因为我的测试上下文不是静态的。

   public TestContext TestContext
   {
      get { return testContextInstance; }
      set { testContextInstance = value; }
   }
   [DeploymentItem("UI.Framework.IntegrationTests''ExpectedValues.xml")]
   [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|''ExpectedValues.xml", "searchTerm2", DataAccessMethod.Sequential)]
   [ClassInitialize()]
   publicstaticvoid ClassInitialize(TestContext context)
   {        
      string indexPath = TestContext.DataRow[0].ToString();
      bool isSuccess1 = SearchApiTestsHelper.InitializeSearchEngine(indexPath, null);
      Assert.IsTrue(isSuccess1);
   }
   

2. 我尝试使用TestInitialize，但数据行没有被加载，它是null。

   [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
               "|DataDirectory|''ExpectedValues.xml", 
               "indices", 
               DataAccessMethod.Sequential),
   TestInitialize()]
   public void MyTestInitialize()
   {
       string indexPath = TestContext.DataRow[0].ToString();
       bool isSuccess1 = SearchApiTestsHelper.InitializeSearchEngine(indexPath, null);
       Assert.IsTrue(isSuccess1);
   }
   

3. 我知道我可以设置每个方法运行两次，但是，有些方法需要不同的数据进行验证。例如，method2仍然需要为每个索引位置运行两次，并且每次运行都要从数据源中断言一组期望的值。

   [DeploymentItem("UI.Framework.IntegrationTests''ExpectedValues.xml")]
   [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
               "|DataDirectory|''ExpectedValues.xml", 
               "pb1", DataAccessMethod.Sequential),
    TestCategory("Integration")]
   [TestMethod]
   public void PhraseBoosting()
   {
       expectedVal = TestContext.DataRow[0].ToString();
   }
   

   如何存档?

<Values>
  <searchTerm2>this is search term 2</searchTerm2>
  <indices>these are the indices</indices>
  <pb1>personal best?</pb1>
</Values>

[TestClass]
    public class UnitTest1
    {
        public TestContext TestContext
        {
            get;
            set;
        }
        //[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|''ExpectedValues.xml", "Values", DataAccessMethod.Sequential)]
        //[ClassInitialize]
        //public static void ClassInitialize(TestContext testContext)
        //{
        //    string indexPath = testContext.DataRow["searchTerm2"].ToString();
        //    Console.WriteLine(indexPath);
        //}
        [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|''ExpectedValues.xml", "Values", DataAccessMethod.Sequential)]
        [TestInitialize]
        public void TestInitialize()
        {
            string indexPath = TestContext.DataRow["indices"].ToString();
            Console.WriteLine(indexPath);
        }
        [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|''ExpectedValues.xml", "Values", DataAccessMethod.Sequential)]        
        [TestMethod]
        public void TestMethod1()
        {
            string indexPath = TestContext.DataRow["pb1"].ToString();
            Console.WriteLine(indexPath);
        }
    }
