docker - 运行单元测试 karma 脚本后的 Jenkins 管道不停止

Question

我创建了一个un jenkins管道，该管道运行带有nodeJs，karma和xvfb的docker容器以运行单元测试。
测试已成功通过，但脚本(即使在karma配置中使用captureTimeout:60000和singleRun:true也不停止)

我错了

没有人可以帮助我，或者可能我不清楚，我的问题是，当我运行我的 Jenkins 管道时，“运行单元测试”步骤从未完成(参见屏幕截图)，并且我无法检查我的测试是否通过或无法启动下一步。我需要帮助，以了解在业力测试完成后如何使用命令行或其他方式停止它。

我尝试使用业力配置使其成功(captureTimeout:60000，singleRun:true)，但是什么也没发生

Answer 1

我认为业力在监视变化，这对开发机器有利，但对CI构建不利。如果要避免更改业力配置，可以将--watch false作为参数传递给ng test。 (尽管您有singleRun: true，但我不确定autoWatch: true是否具有更高的优先级。)

我建议您使用docker容器而不是单个docker-run命令来执行完整的构建。
Jenkins提供了一个很好的抽象来在Docker容器内运行命令:

docker.image('trion/ng-cli-karma').inside {
        stage ('load npm dependencies') {
            echo 'Load npm dependencies'
            sh 'npm install'
        }
        stage ('build') {
            echo "building"
            sh 'npm run build'
        }
        stage ('unit test') {
          sh 'ng test --progress false --watch false'
          echo 'generate test report **/dist/test-reports/*.xml'
          junit allowEmptyResults: false, testResults: '**/test-results.xml'
          echo 'end test & coverage'
        }
   ...
