运行单元测试业力脚本后的詹金斯管道不会停止

Question

我创建了 un jenkins 管道，它运行带有 nodeJs、karma 和 xvfb 的 docker 容器来运行单元测试。 测试成功通过，但即使在 karma 配置中使用 captureTimeout: 60000 和 singleRun: true 脚本也不会停止

我错了

管道：

        def karma = docker.image('trion/ng-cli-karma')
        karma.pull()

        try {

            karma.run(' -u $(id -u) -v ${WORKSPACE}:/app trion/ng-cli-karma ')
            karma.inside {
                sh 'npm install'

                try {
                    sh('ng test')
                }catch(err) {
                    sh 'echo TEST FAILED'
                    step([$class: 'JUnitResultArchiver', testResults: 'report/*.xml', healthScaleFactor: 1.0])
                    throw err
                }
                sh 'echo DO SOMETHING ELSE AFTER TEST'
            }
            sh 'ls -al '
        } catch(err) {
            sh 'echo RUN DOCKER FAILED'
            throw err
        }

编辑时间：2017 年 7 月 4 日 没有人可以帮助我，或者我不清楚，我的问题是当我运行我的詹金斯管道'运行单元测试'步骤从未完成（cf screenshot）并且我无法检查我的测试是否通过或不启动下一步。我需要帮助来了解如何在业力测试完成后使用命令行或其他方式停止它。

我尝试使用业力配置（captureTimeout：60000，singleRun：true）但什么也没发生

Answer 1

我假设 karma 正在观察对开发机器有利但对 CI 构建不利的更改。如果您想避免更改业力配置，可以将--watch false 作为参数传递给ng test。 （虽然你有singleRun: true 我不确定autoWatch: true 是否会有更高的优先级。）

我建议您使用 docker 容器来执行完整的构建，而不是使用单个 docker-run 命令。 Jenkins 提供了一个很好的抽象来在 docker 容器中运行命令：

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'
        }
   ...

Answer 2

我解决了这个问题，之前在我的 Jenkinsfile 中，我使用命令 sh('ng test') 来运行测试，但并不知道后台发生了什么。

所以我直接使用了业力命令

sh ('./node_modules/karma/bin/karma start karma.conf.js')
