Azure DevOps：仅当上一个任务运行时才运行任务

Question

我希望该PublishTestResults@2任务仅在前一个任务script（运行单元测试）实际运行时才运行。

• 如果我使用condition: succeededOrFailed()thenPublishTestResults@2运行，即使上一步没有运行 - 我认为这就是目的condition: always()。

1. 即使前一个任务失败了，如何使任务取决于前一个任务？
2. always()和 和有什么区别succeededOrFailed()？

参考

    # This step only runs if the previous step was successful - OK
    - script: |
        cd $(System.DefaultWorkingDirectory)/application/src
        yarn test:unit --silent --ci --reporters=jest-junit
      displayName: 'Jest Unit Tests'
      env:
        JEST_JUNIT_OUTPUT_DIR: $(System.DefaultWorkingDirectory)/testresults
        JEST_JUNIT_OUTPUT_NAME: 'jest-junit.xml'

    # This step ALWAYS runs - NO
    #  This step should ONLY run if the previous step RAN (success OR fail)
    - task: PublishTestResults@2
      displayName: 'Frontend Test results'
      condition: succeededOrFailed()
      inputs:
        testResultsFormat: JUnit
        searchFolder: $(System.DefaultWorkingDirectory)/testresults
        testResultsFiles: 'jest-junit.xml'
        testRunTitle: 'Frontend Test Results'
        mergeTestResults: false
        failTaskOnFailedTests: true

更新：我怀疑发布步骤“前端测试结果”正在运行，因为前两个步骤未运行，但之前的步骤成功：

Answer 1

succeededOrFailed对于 setp 相当于in(variables['Agent.JobStatus'], 'Succeeded', 'SucceededWithIssues', 'Failed')这就是你Frontend Test results运行的原因。

如果您只想在执行时发布，Jest Unit Tests您可以使用日志命令来设置变量，然后在条件中使用此变量：

 # This step only runs if the previous step was successful - OK
    - script: |
        echo "##vso[task.setvariable variable=doThing;isOutput=true]Yes" #set variable doThing to Yes
        cd $(System.DefaultWorkingDirectory)/application/src
        yarn test:unit --silent --ci --reporters=jest-junit
      displayName: 'Jest Unit Tests'
      name: JestUnitTests
      env:
        JEST_JUNIT_OUTPUT_DIR: $(System.DefaultWorkingDirectory)/testresults
        JEST_JUNIT_OUTPUT_NAME: 'jest-junit.xml'

    # This step ALWAYS runs - NO
    #  This step should ONLY run if the previous step RAN (success OR fail)
    - task: PublishTestResults@2
      displayName: 'Frontend Test results'
      condition: and(succeededOrFailed(), eq(variables['JestUnitTests.doThing'], 'Yes'))
      inputs:
        testResultsFormat: JUnit
        searchFolder: $(System.DefaultWorkingDirectory)/testresults
        testResultsFiles: 'jest-junit.xml'
        testRunTitle: 'Frontend Test Results'
        mergeTestResults: false
        failTaskOnFailedTests: true
