问题描述
我正在使用 VsTest 在 azure dev ops 上运行我的 nUnit 测试并失败。这在我的本地机器上运行良好，但在 Azure DevOps 版本中运行良好。这是我从日志中看到的错误。它并没有给我太多的东西去追踪什么可能是错误的。我认为它可能在我的 .runsettings 文件中，但这与我在本地使用的文件相同，这很好。我的运行设置文件使用了使用代码覆盖率和录像机的数据收集器。我不知道这是否是导致测试失败的原因。如果我确实想使用它，那可能是什么原因造成的，有没有办法下载这些 dll 供服务器使用，或者这些 dll 是否通过 vs 工具安装程序自动下载？
这是当前任务
- 将文件复制到：$(System.DefaultWorkingDirectory) - 成功
- Visual Studio 测试平台安装程序 - 安装 VS 2017 - 成功
- VSTest - 我选择测试计划 -
- 失败 - 选择测试平台 - 由工具安装程序安装
- 我选择我的 .runsettings 文件的路径
- 我给出了覆盖测试运行参数
- 我检查代码覆盖启用
这是我收到的错误
