测试失败时 Jenkins 中的 Docker 多阶段构建访问测试报告

Question

I am doing a multi stage build in docker to separate the app from testing. Now at some point in my Dockerfile I run:

RUN pytest --junit=test-reports/junit.xml

In my Jenkinsfile respectivly I do:

def app = docker.build("app:${BUILD_NUMBER}", "--target test .")
app.inside {
  sh "cp -r /app/test-reports test-reports"
}

junit 'test-reports/junit.xml'

Now if my test fail, the build fails which is good. But the rest of the stage is not executed, ie I dont have access to the test-reports folder. How can I manage that?

I resolved similar task by using always block after build stage. Please check if below code can help.

always{
    script{
        sh '''#!/bin/bash
        docker create -it --name test_report app:${BUILD_NUMBER} /bin/bash
        docker cp test_report:/app/test-reports ./test-reports
        docker rm -f test_report
        '''
    }

    junit 'test-reports/junit.xml'
}
