如何在 VSTS 中使用 NUnit？

Question

我正在尝试在 Visual Studio Team System 中使用 NUnit 3，他们似乎真的很难做到。我在构建过程和高级执行选项中添加了测试程序集步骤 -> 自定义测试适配器的路径，我已按照建议放入 NUnitVisualStudioTestAdapter-2.0.0.vsix 插件的目录路径在帮助中。

无论我做什么，它似乎都没有找到或尝试运行它。它只是运行 Visual Studio 测试并报告未找到任何测试。我也尝试将测试适配器作为 NuGet 包和工具的路径放入其中，但这也不起作用。

有没有人设法让 NUnit 在 VSTS 中工作并返回测试结果？

我得到的日志是：

更新：

我已将 NUnit3TestAdapter 包安装到单元测试项目中。我已经修改了 VSTS 中的构建步骤：

这是版本 2.*（预览版）

搜索模式是： *测试*.dll !\obj** 在高级执行选项中，我将自定义测试适配器的路径设置为 $(Build.SourcesDirectory)\

然后我得到这个调试信息，所以至少它已经找到了测试适配器，如果不是现在的测试：

Answer 1

自定义测试适配器的路径必须指向提取的 vsix 或提取的 NuGet 包。

完成这项工作的最简单方法是将NUnit Test Adapter NuGet package 2.x/3.x 添加到您的单元测试项目中。 VsTest 任务应自动检测恢复到 NuGet 包目录的测试运行程序：

确保 nunit.framework 版本和 NUnit 适配器版本匹配。确保将两个包都添加到您的测试项目中。

Answer 2

您原始帖子中的问题是 Visual Studio 测试任务找不到您要测试的测试程序集 (App.Web.Unit.Tests.dll)。在您的更新中，将搜索模式更改为“*test.dll”后，它仍然找不到测试程序集。它只是找到“NUnit3.TestAdapter.dll”，这是 NUnit 测试适配器的二进制文件，二进制文件不包含任何测试方法。因此，您需要检查构建日志以查看构建步骤中是否正确生成了测试程序集以及它的路径是什么，然后根据路径设置搜索模式。

更新：

根据您提供的日志，输出文件放置在“D:\a\1\a”文件夹中，因为您指定了参数“/p:OutDir=D:\a\1\a”。尝试将搜索模式更改为： D:\a\1\a\*.Unit.Tests.dll 或 $(build.stagingDirectory)\*.Unit.Tests.dll
