msbuild - VSTS Build 无法运行 NUnit 测试

Question

当使用 Visual Studio 团队服务构建 Visual Studio 解决方案时，它运行单元测试，使用 nunit 3 NUnit3TestAdapter 在 nunit 3 中编写，它开始运行测试。

它给出的错误是：错误：路径中有非法字符。

完整输出如下

我们有一个内部构建代理，但我认为这不会产生影响。

您可以提供的任何建议表示赞赏。

FWIW，我按照提示和技巧打开了详细日志记录并得到了这个：

这与%LOCALAPPDATA%\NUnit\Nunit30Settings.xml被访问相关，但可能不相关。ExtensionService在这里。

问题#117和#118与RobertK66提供的修复相关：

如果您将版本 3.0.8.0 安装为 Nuget 包，则在 packages\NUnit3TestAdapter.3.0.8-ctp-8\lib 文件夹中安装了一个损坏的（不是空的！）“ignore.addins”文件。早期版本确实安装了一个 0byte 的空文件！

在 /packages/NUnit3TestAdapter.3.0.8-ctp-8\lib 文件夹中删除此文件的内容并删除 \AppData\Local\Temp\VisualStudioTestExplorerExtensions 下的适配器的缓存版本后...一切正常！

Answer 2

我在构建过程中使用NUnit3 测试适配器 Nuget 包时遇到了这个问题。我通过安装NUnit3 测试适配器解决了这个问题，并将所有安装的文件上传到版本控制并将其用作测试适配器。

由于您使用的是本地构建代理。您可以轻松地在构建代理上安装 NUnit3 测试适配器，并按照错误消息的指示使用“/UseVsixExtensions:true”参数。
