我有一个测试方法,它调用2个子测试方法.子方法都是从XML文件驱动的数据.如果我运行每个子方法,它们运行良好且成功.但是,当我运行主测试方法(两个子方法的调用者)时,它发现TestContext.DataConnection和TestContext.DataRow为null.

    private TestContext testContext;
    public TestContext TestContext
    {
        get { return testContext; }
        set { testContext = value; }
    }
    [TestMethod]
    public void SaveEmpty_Json_LocalStorage()
    {
        // Testing JSON Type format export and save
         SetWindowsUsers();
        // Add Network Information
        SetWifiInformation();

        // More logic and assertions here.
        // More logic and assertions here.
        // More logic and assertions here.
    }

    [TestMethod]
    [DeploymentItem("input.xml")]
    [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
               "input.xml",
               "User",
                DataAccessMethod.Sequential)]
    public void SetWindowsUsers()
    {
      Console.WriteLine(TestContext.DataRow["UserName"].ToString())
      // MORE LOGIC and Asserts  
    }

    [TestMethod]
    [DeploymentItem("input.xml")]
    [DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
               "input.xml",
               "WifiList", …
