使用 xUnit 适配器在 TFS/VSO Build vNext 中运行单元测试

Question

我正在尝试使用 Visual Studio Online 的 Build vNext 平台中的 xUnit 测试适配器运行我们的 xUnit 测试。

按照this article的规定，我们需要提供一个自定义的测试适配器路径指向xunit.runner.visualstudio.testadapter.dll。

但是这个包被NuGet还原到一个全局包文件夹，即C:\Users\{user}\.dnx\packages?

如何在构建步骤中引用此文件夹？

我们正在使用 VS 2015 和 DNX 项目。

编辑：

我什至尝试过直接指向包路径DLL：

C:\Users\buildagent\.dnx\packages\xunit.runner.visualstudio\2.1.0-beta4-build1109\build\_common

它似乎仍然没有使用适配器：

Executing C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe "C:\a\8ac4a4f6\Root\artifacts\bin\MyProject.UnitTest\release\dnx451\TransitApi.UnitTest.dll"  /TestAdapterPath:C:\Users\buildguest\.dnx\packages\xunit.runner.visualstudio\2.1.0-beta4-build1109\build\_common /UseVsixExtensions:true /logger:trx

project.json，如果相关：

}

Answer 1

创建一个global.json 文件并将以下内容放入其中：

{
  "packages": "packages"
}

这将迫使您的dnu restore 将包放入.\packages\，这有望解决问题。只需将测试适配器路径指定为 $(Build.SourcesDirectory)\packages\ ——您可能必须指定完整的程序集名称，我不确定我的想法。

更新：我采用了示例“HelloMvc”应用程序，并使用 xUnit 测试构建它，而没有 global.json。这是我的构建定义：

我怀疑问题在于您正在尝试使用 Visual Studio 测试适配器。

Answer 2

我在使用 NUnit 测试适配器查找正确路径时遇到了类似的问题，这是我在测试步骤中使用的最终对我有用的路径，也可能对您有用：

"$(Build.SourcesDirectory)[你的包文件夹路径]\packages\NUnit3TestAdapter.3.8.0\build\netcoreapp1.0"

测试适配器 dll 位于 netcoreapp1.0 文件夹中。此外，保留路径周围的引号。
