如何在运行时从 NUnit 测试运行中获取单元测试方法属性?

问题描述 投票:0回答:3

我将有关给定测试的各种信息(多个错误跟踪系统的 ID)存储在属性中,如下所示:

[TestCaseVersion("001","B-8345","X543")]
public void TestSomethingOrOther()

为了在测试过程中获取这些信息,我编写了以下代码:

     public string GetTestID()
     {
        StackTrace st = new StackTrace(1);
        StackFrame sf;
        for (int i = 1; i <= st.FrameCount; i++)
        {
            sf = st.GetFrame(i);
            if (null == sf) continue;
            MethodBase method = sf.GetMethod();
            if (method.GetCustomAttributes(typeof(TestAttribute), true).Length == 1)
            {
                if (method.GetCustomAttributes(typeof(TestCaseVersion), true).Length == 1)
                {
                    TestCaseVersion tcv =
                        sf.GetMethod().GetCustomAttributes(typeof(TestCaseVersion), true).OfType<TestCaseVersion>()
                            .First();
                    return tcv.TestID;
                }
            }
        }

问题是,当在Release模式下通过NUnit运行测试时,应该具有测试名称和这些属性的方法被以下内容替换:

System.RuntimeMethodHandle._InvokeMethodFast(IRuntimeMethodInfo method, Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeType typeOwner)
   at System.RuntimeMethodHandle.InvokeMethodFast(IRuntimeMethodInfo method, Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeType typeOwner)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
   at NUnit.Core.Reflect.InvokeMethod(MethodInfo method, Object fixture, Object[] args)

更新 对于任何感兴趣的人,我最终以以下方式实现代码(以便可以访问任何属性值,而无需更改任何使用 TestCaseVersion 属性的现有代码:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Interface | AttributeTargets.Method, AllowMultiple = false)]
public class TestCaseVersion : PropertyAttribute
{
   public TestCaseVersion(string testCaseCode, string story, string task, string description)
   {
      base.Properties.Add("TestId", testCaseCode);
      base.Properties.Add("Description", description);
      base.Properties.Add("StoryId", story);
      base.Properties.Add("TaskId", task);
    }
}

public string GetTestID()
{
   return TestContext.CurrentContext.Test.Properties["TestId"];
}

如果您同意使用单值测试用例版本字符串(即

"001, B-8345, X543"
而不是
"001","B-8345","X543"
),您应该能够使用 NUnit 2.5.7 及更高版本中提供的 TestContext 功能.

具体来说,您可以像这样定义和使用测试上下文 Property 属性 TestCaseVersion

[Test, Property("TestCaseVersion", "001, B-8345, X543")]
public void TestContextPropertyTest()
{
    Console.WriteLine(TestContext.CurrentContext.Test.Properties["TestCaseVersion"]);
}

更新顺便说一句,如果您do想使用测试用例版本的多值表示,您可以定义多个属性,如下所示:

[Test, Property("MajorVersion", "001"), 
 Property("MinorVersion", "B-8345"), Property("Build", "X543")]
public void TestContextPropertyTest()
{
    Console.WriteLine(TestContext.CurrentContext.Test.Properties["MajorVersion"]);
    Console.WriteLine(TestContext.CurrentContext.Test.Properties["MinorVersion"]);
    Console.WriteLine(TestContext.CurrentContext.Test.Properties["Build"]);
}

可能我不明白你的想法,但为什么不使用更简单的解决方案呢?

[TestCase(TestName = "001, B-8345, X543")]
public void TestSomethingOrOther()

大家好,我对解决方案有疑问,如果像我的示例中那样做,我会得到 null 返回

    [SetUp]
        public async Task SetUp()
        {
            var test = TestContext.CurrentContext.Test.Properties["Testkey"];
            checkVersionAndTestName.CheckVersionAndTest(name, page, browser);
        }
[Test, Property("Testkey", "MES-39432")]
        [Retry(3)]
        [TestCase("TA-Playwright", "Vf7e92ljKanZ", "//*[@id='__toolbar13']",
            TestName = "MES-39432-TestCase1",
