如何正确使用 TestContext.Properties

Question

我需要TestContext.Properties在 a 之前访问，TestMethod以便测试可以接收正确的环境进行测试。

---

我的内容test.runsettings：

<?xml version="1.0" encoding="utf-8"?>
  <RunSettings>
    <TestRunParameters>
      <Parameter name="colegio" value="7" />
    </TestRunParameters>

如您所见，该文件仅包含一个参数，称为 colegio (school)

这是内容TestBase.cs：

using Microsoft.VisualStudio.TestTools.UnitTesting;
using InfraestructureSelenium.Helper;
using System.Collections.Generic;
using InfraestructureSelenium.Configuration.Enumerados;

namespace TestSelenium
{
    [DeploymentItem("chromedriver.exe")]
    [DeploymentItem("IEDriverServer.exe")]
    [DeploymentItem("phantomjs.exe")]
    [DeploymentItem("geckodriver.exe")]
    [TestClass]
    public class TestBase
    {
        protected TestBase()
        { }

        public TestBase(int id = (int)ColegioEnum.ColegioDemoMovilidad2_Supervisor)
        {
            DiccionarioCompartido = new Dictionary<string, string>();
            SeleniumHelper = new HelperSelenium(id, WebDriverSelector.ObtenerWebDriver());
        }

        public TestBase(HelperSelenium seleniumHelper, Dictionary<string, string> diccionarioCompartido = null)
        {
            SeleniumHelper = seleniumHelper;
        }

        public HelperSelenium SeleniumHelper { get; set; }

        public static Dictionary<string, string> DiccionarioCompartido { get; set; }

        public void CloseBrowser()
        {
            SeleniumHelper.Quit();
        }

        #region Configuración Test

        [TestInitialize]
        public void InitializeTest()
        {

        }

        [TestCleanup]
        public void TestCleanupTest()
        {
            SeleniumHelper.Quit();
        }

        #endregion
        }
    }

如您所见，public TestBase(int id = (int)ColegioEnum.ColegioDemoMovilidad2_Supervisor)接收一个参数，它对应于colegio我要测试的环境。如果 nocolegio作为参数传递，则默认值为ColegioEnum.ColegioDemoMovilidad2_Supervisor

但是，当我尝试TestContext在 a 中实例化时TestClass，如下所示：

[TestClass]
    public class GenerarBoletinDeClase : TestBase
    {
        public TestContext TestContext { get; set; }

        private static TestContext _testContext;

        [TestInitialize]
        public static void SetupTests(TestContext testContext)
        {
            _testContext = testContext;
        }

        public GenerarBoletinDeClase() : base((int)TestContext.Properties["colegio"]) { }

出现以下错误： An object reference is required for the non-static field, method, or property

感谢任何帮助，因为我已经给了这个问题很多时间，但我无法继续前进。

首先，感谢@Peska提供了这个答案中的代码/sf/answers/3595706201/

所以，最后我所做的是将以下代码添加到类中TestBase：

public class TestBase
{
    public TestContext TestContext { get; set; }

    public static int Colegio { get; set; }

    [AssemblyInitialize]
    public static void ClassInitialize(TestContext TestContext)
    {
        Colegio = int.Parse(TestContext.Properties["colegio"].ToString()); // colegio is equal 7 in here
    }

    public TestBase()
    {
        SeleniumHelper = new HelperSelenium(Colegio, WebDriverSelector.ObtenerWebDriver());
        DiccionarioCompartido = new Dictionary<string, string>();
    }

我相信装饰器[AssemblyInitialize]是必要的，[ClassInitialize]但[TestInitialize]不会起作用，因为 TestContext 尚未实例化。

之后，确保您已Test Settings File通过转到配置Test > Test Settings > Select Test Settings File，该文件必须命名为*.runsettings

这样，一切都应该设置为TestContext.Properties从测试设置文件中读取
