封面报道报告导致 Microsoft.VisualStudio.Coverage.VanguardException
coverlet coverage report resulting in Microsoft.VisualStudio.Coverage.VanguardException
我正在尝试将 Cobertura 报告生成集成到我的 Azure 管道中。为此，我在我的 .Net 核心测试项目中添加了 coverlet.collector 3.0.3。下面是我用于测试的 yaml 命令 运行
- task: DotNetCoreCLI@2
displayName: Test
inputs:
command: test
projects: '**/*Test/*.csproj'
arguments: '--collect:"XPlat Code Coverage" --settings CodeCoverage.runsettings --logger trx'
publishTestResults: false
我使用 Reportgenerator 任务来合并和发布覆盖率报告。这一切在我的代码的一个分支（一个旧分支，我前一段时间开始在其上设置管道）中都运行良好。但是当我试图指向管道中的最新分支时，出现如下错误
Data collector 'Code Coverage' message: Data collector caught an exception of type 'Microsoft.VisualStudio.Coverage.VanguardException': 'Running event not received from CodeCoverage.exe. Check eventlogs for failure reason
我几乎检查了两个分支中的所有内容，Microsoft.Net.Test.SDK、coverlet.collector，两者的版本相同。我不确定 2 个分支之间有什么区别以及我应该在 2 个代码分支之间寻找哪些差异，这可能会导致此类问题。
下面添加了成功和失败的完整日志。

我也遇到了这个问题线程：https://github.com/microsoft/azure-pipelines-agent/issues/2839 用户怀疑它是代理升级问题，但对我来说似乎不是这种情况，因为我能够 运行 它成功地用于一个代码分支。
如有任何建议或指导，我们将不胜感激。
当我向 Coverlet 团队提出这个问题时，我得到了他们的快速回复。他们注意到了一些我完全错过的东西。
Microsoft (R) Coverage Collection Tool Version 16.0.30319.3002
这出现在我的成功日志中，这意味着 Microsoft 代码覆盖率 运行ning 与 Coverlet 代码覆盖率并行。他们怀疑如果你同时有两个代码覆盖收集器 运行ning，我们会得到一些奇怪的错误，并且两个分支中的测试方式 运行 之间的一些时间问题会导致不同的行为。
我在 .运行settings 文件中禁用了 Microsoft 代码覆盖后，问题就得到了解决
