将任务拆分为单独的作业后未找到测试

Question

我正在尝试通过将一些任务拆分为单独的作业来重构我的构建管道以实现可扩展性。

以下工作完美，测试找到并运行没有问题。

stages:
  - stage: build_test_publish
    displayName: Build
    pool:
      vmImage: "windows-latest"
    variables:
      solution: "**/SolutionName.sln"
      buildPlatform: "Any CPU"
      buildConfiguration: "Release"
    jobs:
      - job: build_publish_artifacts
        displayName: "Build, test and publish artifacts"
        steps:
          - task: NuGetToolInstaller@1
          - task: NuGetCommand@2
            inputs:
              command: "restore"
              restoreSolution: "**/*.sln"
              feedsToUse: "select"
              vstsFeed: "xxx"

          - task: VSBuild@1
            inputs:
              solution: "$(solution)"
              msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
              platform: "$(buildPlatform)"
              configuration: "$(buildConfiguration)"

          - task: VSTest@2
            inputs:
              platform: '$(buildPlatform)'
              configuration: '$(buildConfiguration)'
              runInParallel: false
              codeCoverageEnabled: true
              testAssemblyVer2: |
                 **\*test*.dll
                 !**\ProjectName.IntegrationTests.dll
                 !**\*TestAdapter.dll
                 !**\obj\**
              searchFolder: '$(System.DefaultWorkingDirectory)'

但是，像下面这样拆分后，我得到以下输出，其中找不到任何测试。

stages:
  - stage: build_test_publish
    displayName: Build, test and publish artifacts
    pool:
      vmImage: "windows-latest"
    variables:
      solution: "**/SolutionName.sln"
      buildPlatform: "Any CPU"
      buildConfiguration: "Release"
    jobs: 
      - job: build
        displayName: "Build"
        steps:
          - task: NuGetToolInstaller@1
          - task: NuGetCommand@2
            inputs:
              command: "restore"
              restoreSolution: "**/*.sln"
              feedsToUse: "select"
              vstsFeed: "xxx"
          - task: VSBuild@1
            inputs:
              solution: "$(solution)"
              msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
              platform: "$(buildPlatform)"
              configuration: "$(buildConfiguration)"
                

      - job: test
        displayName: Run unit tests
        dependsOn: build
        steps:
          - task: VSTest@2
            inputs:
              platform: '$(buildPlatform)'
              configuration: '$(buildConfiguration)'
              runInParallel: false
              codeCoverageEnabled: true
              testAssemblyVer2: |
                 **\*test*.dll
                 !**\ProjectName.IntegrationTests.dll
                 !**\*TestAdapter.dll
                 !**\obj\**
              searchFolder: '$(System.DefaultWorkingDirectory)'

Task         : Visual Studio Test
Description  : Run unit and functional tests (Selenium, Appium, Coded UI test, etc.) using the Visual Studio Test (VsTest) runner. Test frameworks that have a Visual Studio test adapter such as MsTest, xUnit, NUnit, Chutzpah (for JavaScript tests using QUnit, Mocha and Jasmine), etc. can be run. Tests can be distributed on multiple agents using this task (version 2).

为什么会发生这种情况，我应该改变或重新考虑什么？

**编辑 似乎可能是因为每个作业都使用自己的代理来运行其作业中的任务。

我仍然想知道这样的事情是否可以使用不同的环境变量开始测试运行

Answer 1

DLL 的产生者

          - task: VSBuild@1
            inputs:
              solution: "$(solution)"
              msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
              platform: "$(buildPlatform)"
              configuration: "$(buildConfiguration)"

在开箱即用的作业之间不共享。在场景拆分任务的背后，您在不同的机器上运行 VSBuild 和 VSTask。这样做没有多大意义——我的意思是把这两个任务分开。

但是，如果您仍然想这样做，您需要publish artifact and download it in next job。
