我有一个 .net 框架 (v4.8) 类库项目，其中包含 18个针对另一个项目的xUnit.net单元测试。
在我的Azure DevOps Server (ADOS)管道中，我有一个相当标准的 Visual Studio 测试任务，可以找到带有单元测试的测试程序集并运行它们。
当我在管道任务上启用“仅运行受影响的测试”功能时，ADOS 在第一次构建时运行所有这些，这是正常的，因为这成为基线构建。
在管道的第二次构建中，事情变得很奇怪。ADOS 显示构建有 36 个单元测试，其中 18 个“未受影响”（跳过 = 正常），18 个已执行并“通过”。
我的问题是 -为什么我的单元测试被认为“不受影响”时会执行？我怎样才能解决这个问题？
PS - 我附上了截图和下面的任务日志，我注意到了两件有趣的事情：
- 看起来测试选择阶段在一开始就发生了两次。
此错误消息出现 18 次：
TcmTestResultPublisher.ConvertResults : 没有为代理提供给发布者的测试用例结果找到匹配的 tcm 测试用例结果。添加测试用例 : ... 以测试运行。
