在Azure Devops中哪里可以找到失败的VSTest的日志？

问题描述

在VNET内的Windows 2019 VM中的托管代理上运行运行Azure服务的Azure Devops管道。部署任务的最后一步是运行集成测试，但失败，并显示无用的堆栈跟踪（Microsoft调用堆栈）。

这是该步骤的YAML：

steps:
- task: VSTest@2
  displayName: 'Run Integration Tests'
  inputs:
    testAssemblyVer2: '$(System.DefaultWorkingDirectory)/_FooService pipeline/drop/output/FooServiceTests.Integration.dll'

这是devops日志的最后一点

在哪里可以找到日志以显示有关测试失败原因的更多详细信息？

解决方法

事实证明，发布管道URL变量不正确，导致测试中的http客户端失败。最终不得不添加一些测试代码以使用ITestOutputHelper记录URL，以便在测试失败的情况下我们可以轻松地查看服务URL。
