c#-ClassInitialize上的数据驱动单元测试

我试图每次使用不同的值运行一些测试.例如：我有3种方法：methodA,methodB和methodC.我想在不同的索引位置运行两次每个方法.我有TestInitialize和ClassInitialize方法.

>我尝试使用ClassInitialize,但未成功；我收到编译时错误,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);
}

我做不到
>我尝试使用TestInitialize,但未加载数据行,它为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);
}

>我知道我可以将每个方法设置为运行两次,但是,某些方法需要不同的数据进行验证.例如method2仍需要为每个索引位置运行两次,并且每次运行都声明来自数据源的一组期望值.

[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();
}

如何将其归档？

解决方法:

假设这样的XML文件：

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

您可以像这样访问这些值：

[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);
        }
    }

类的initialize方法似乎不起作用.我不确定这是否是设计使然.
