Question

我使用预览模板在Visual Studio 2015中创建了一个ASP.NET 5项目。我通过NuGet安装了XUnit，并在我的解决方案中添加了“xUnit Test Project（DNX）”。

但我的Test Explorer没有显示任何内容，即使我在Class1.cs中有一个公共的“Fact”测试方法。当我“运行所有测试”时，“测试”输出窗口为空白。我的“Build”输出窗口显示2个项目构建成功。（我的ASP.NET 5项目和我的xUnit项目。）

但是，当我构建或清理我的解决方案时，我在“测试”输出窗口中收到以下消息：

------ Discover test started ------
------ Test started: Project: MyProjectTest ------
Starting  Microsoft.Dnx.TestHost [C:\Users\xxxxxx\.dnx\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\dnx.exe --appbase "C:\Users\xxxxxx\Documents\GitForWindows\Repositories\MySolution\MyProjectTest" Microsoft.Dnx.ApplicationHost --port 8424 Microsoft.Dnx.TestHost --port 8458 --parentProcessId 17312]

System.NullReferenceException: Object reference not set to an instance of an object.

Unable to start Microsoft.Dnx.TestHost
========== Discover test finished: 0 found (0:00:01.057196) ==========

根据两个项目的属性窗口，我的解决方案DNX SDK版本是1.0.0-rc1-update1。我还通过dnvm将其设置为“活动”运行时，上述行为没有变化。但是，我不了解从命令行运行DNX的说明，所以也许这是一个起点？

当我尝试将DNX SDK切换到1.0.0-beta5而不是清洁解决方案时，我得到：

------ Discover test started ------
------ Test started: Project: MyProjectTest ------
Starting  Microsoft.Framework.TestHost [C:\Users\xxxxx\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta5\bin\dnx.exe --appbase "C:\Users\xxxxxx\Documents\GitForWindows\Repositories\MySolution\MyProjectTest" Microsoft.Framework.ApplicationHost --port 9737 Microsoft.Framework.TestHost --port 9770 --parentProcessId 16732]

System.InvalidOperationException: Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1':

Try running 'dnu restore'.

运行DNU还原无法解决任何问题。

编辑：这是请求的project.json：

  "version": "1.0.0-*",
  "description": "",
  "authors": [ "" ],
  "tags": [ "" ],

您需要使用与dnx匹配的xUnit运行版本。对于dxn RC1，您需要使用xunit.runner.dnx的版本2.1.0-rc1-build204

Visual Studio 2015中的XUnit RC1 Update 1找不到测试
