VS2017实时单元测试 - 仅减去 - 不起作用

Jer*_*son 41 .net c# unit-testing visual-studio-2017 live-unit-tests

TL; DR; 编辑6:我缩小了它并提供了5个步骤来重现问题/错误.

  1. 创建VS2017 c#控制台应用程序(.Net完整框架)
  2. 将方法添加到Program.cs并使该类公开:

 

public class Program
{
    static void Main(string[] args)
    {
    }

    public int Add(int a, int b)
    { 
        return a + b;
    }
}
}

  1. 右键单击AddMethod并选择Create Unit Test:

  1. 使用这些设置可以使用测试创建新的单元测试项目:

  1. 添加单元测试

 

[TestMethod()]
public void AddTest()
{
    Program p = new Program();
    var r = p.Add(1, 2);

    Assert.IsTrue(3 == r);
}

  • 测试菜单>实时单元测试>开始
  • AddTest()> Live Testing> Include上的上下文菜单

现在将Add的+符号更改为-

Live Unit Testing工作,将-符号改 回+,Live Test通过!!

现在添加对Nuget DLL的引用(任何人都可以) - 实时单元测试不再有效!或者只需关闭解决方案,重新打开它,Live Unit Testing就不再有效了!

我已经设置了一个MSUnitTest v2项目并启动了Live Unit Testing.我正在使用Web Api 2 .Net项目(Full Framework v4.5.2).

我看到Minus标志到处都是,但没有Tick或十字架.

我改变代码的方式与在Visual Studio 2017视频中的实时单元测试中的代码相同,时钟显示在减号上但没有任何内容......

单调测试将在我调试时通过:

当我将鼠标悬停在蓝色减号上时,消息为"由0测试覆盖"

我发现你需要MSTest.TestAdapter和MSTest.TestFramework,按照https://developercommunity.visualstudio.com/content/problem/5520/live-unit-test-are-only-showing-minuses-using-micr.我已经完成的HTML并且引用了V1.18:

  • Microsoft.VisualStudio.TestPlatform.TestFramework
  • Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions

有一群beta测试者报告了同样的问题:

所有帖子都已解决或无法解决.

此Stackoverflow用户遇到了Live Unit Testing的问题,但它出现了Null Exception问题.我在评论中尝试了解决方案从Gac中删除Microsoft.VisualStudio.QualityTools.UnitTestFramework,当我尝试从C:\ Windows\assembly卸载时,我获得了访问被拒绝并通过开发人员命令提示符卸载:

GacUtil /u Microsoft.VisualStudio.QualityTools.UnitTestFramework
Run Code Online (Sandbox Code Playgroud)

结果是:

程序集:Microsoft.VisualStudio.QualityTools.UnitTestFramework,Version = 10.0.0.0,Culture = neutral,PublicKeyToken = b03f5f7f11d50a3a,processorArchitecture = MSIL无法卸载:一个或多个应用程序需要汇编

有人可以帮助我让Live Unit Testing工作吗？

在VS>工具>选项>实时单元测试中,我将日志记录转换为详细信息.

看看输出,我看到一个警告:

[15:48:26.521详细] - TestDriver - TestDiscoverer日志消息:警告 - 配置系统初始化失败

在之后的几个答案,这我还是无法摆脱的"配置系统初始化失败" -不知道这是一个红鲱鱼与否,它到目前为止,我已经找到了唯一的线索......

编辑2:

我运行VS2017作为管理员,摆脱了"配置系统无法初始化".不幸的是,以管理员身份运行没有任何区别,它仍然不起作用,但不会因任何异常而失败.

这是详细日志.有趣的是"准备开始测试发现"看起来像我发现的x86测试我已经包含.

但是,它显然无法发现测试; "发现0测试"

我今天看了一下ProcessMonitor的痕迹......没有什么真正脱颖而出,我可能错过了一些东西,但我开始觉得这是一个bug而不是配置问题.

我正在一个非常锁定的环境中工作,因此在vs2017安装期间可能会阻止某些内容.我知道Unity3D域名没有下载白名单.虽然安装了所有核心Visual Studio Microsoft内容.我开始用完诊断故障排除策略了.任何想法都非常欢迎!

今天早上我决定Microsoft.VisualStudio.QualityTools.UnitTestFramework从GAC中删除DLL.我遵循这些说明来克服拒绝访问:

这导致找到潜在的根本原因之一.我开始看到Live Unit Testing Logging输出:

这仍然不能正常工作,但它似乎我越来越近的直播单元测试正在长一点不工作(即出现负的取顶更长的时间来处理时钟).

然后我再次尝试了ProcMon,它显示了一些有趣的日志,但没有吸烟枪.

根据这篇博客:https: //blogs.msdn.microsoft.com/visualstudio/2017/03/09/live-unit-testing-in-visual-studio-2017-enterprise/

问:为什么在我从Live Test Set中包含或排除测试后没有任何反应？

答:这是一个我们无法在Visual Studio 2017 15.0版中修复的已知问题.它现在已在Visual Studio 2017版本15.2中修复.

原来我有Visual Studio/15.0.0 +26228.9.升级到Visual Studio 2017年(v15.2)DOES NOT解决问题.

我已将此问题报告给https://developercommunity.visualstudio.com,并会将所有人发布.它正确地没有报告环境被锁定.

更新： MS 说它已在 15.3.2 中修复

好的，我已经缩小范围了。

当您向单元测试项目添加 NuGet 引用时，它会添加一个packages.config ，并且在某些情况下可能会添加一个App.Config 文件。

当我添加Oracle.ManagedDataAccess时，以下内容将添加到 App.Config 中：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!--<configSections>
    <section name="oracle.manageddataaccess.client"

请注意我如何注释掉<!--<configSections ... configSections>-->，纯粹通过排除过程，我发现它的这个特定 App.Config 标记导致实时单元测试失败。
