我的一些UnitTest具有在循环中定义的Sleep。我不仅要描述测试的每个迭代，还要描述所有迭代的总时间，以显示任何非线性缩放比例。例如，如果我分析“总体”，则它包括 sleep 时间。我可以使用Stopwatch Start/Stop，以便它仅包含doAction()。但是，我无法将秒表结果写入TestContext结果。

[TestMethod]
    public void TestMethod1()
    {
        TestContext.BeginTimer("Overall");
        for (int i = 0; i < 5; i++)
        {
            TestContext.BeginTimer("Per");
            doAction();
            TestContext.EndTimer("Per");
            Sleep(1000);
        }
        TestContext.EndTimer("Overall");
    }

最佳答案

好吧，我有一个类似的问题。我想像Visual Studio一样在最终测试结果中报告测试中的一些额外数据/报告/计数器，因此我找到了解决方案。

首先，这无法通过您尝试的方式完成。在存在TestContext的负载测试和单元测试之间没有直接链接。

其次，您必须了解Visual Studio如何创建报告。它从操作系统的performance counters收集数据。您可以编辑这些计数器，删除不需要的计数器，然后添加所需的其他计数器。

如何编辑计数器

负载测试配置有两个关于计数器的基本部分。这些都是:

void CreateCounter() 
{
    if (PerformanceCounterCategory.Exists("MyCounters"))
    {
        PerformanceCounterCategory.Delete("MyCounters");
    }

    //Create the Counters collection and add your custom counters 
    CounterCreationDataCollection counters = new CounterCreationDataCollection();
    // The name of the counter is Delay
    counters.Add(new CounterCreationData("Delay", "Keeps the actual delay", PerformanceCounterType.AverageCount64));
    // .... Add the rest counters

    // Create the custom counter category
    PerformanceCounterCategory.Create("MyCounters", "Custom Performance Counters", PerformanceCounterCategoryType.MultiInstance, counters);
}

[TestClass]
public class UnitTest1
{
    PerformanceCounter OverallDelay;
    PerformanceCounter PerDelay;

    [ClassInitialize]
    public static void ClassInitialize(TestContext TestContext)
    {
        // Create the instances of the counters for the current test
        // Initialize it here so it will created only once for this test class
        OverallDelay= new PerformanceCounter("MyCounters", "Delay", "Overall", false));
        PerDelay= new PerformanceCounter("MyCounters", "Delay", "Per", false));
        // .... Add the rest counters instances
    }

    [ClassCleanup]
    public void CleanUp()
    {
        // Reset the counters and remove the counter instances
        OverallDelay.RawValue = 0;
        OverallDelay.EndInit();
        OverallDelay.RemoveInstance();
        OverallDelay.Dispose();
        PerDelay.RawValue = 0;
        PerDelay.EndInit();
        PerDelay.RemoveInstance();
        PerDelay.Dispose();
    }

    [TestMethod]
    public void TestMethod1()
    {
         // Use stopwatch to keep track of the the delay
         Stopwatch overall = new Stopwatch();
         Stopwatch per = new Stopwatch();

         overall.Start();

         for (int i = 0; i < 5; i++)
         {
             per.Start();
             doAction();
             per.Stop();

             // Update the "Per" instance of the "Delay" counter for each doAction on every test
             PerDelay.Incerement(per.ElapsedMilliseconds);
             Sleep(1000);

             per.Reset();
         }

         overall.Stop();

         // Update the "Overall" instance of the "Delay" counter on every test
         OverallDelay.Incerement(overall.ElapsedMilliseconds);
     }
}

关于c# - 我可以在Visual Studio中为单元测试/负载测试创建自定义TestContext计时器吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16901453/
