Answer 1

我用dockerize来绕过这个问题。

涉及3个步骤。

1. 在后台运行应用程序
2. 使用dockerize等待端口打开（这在应用程序侦听cretin端口时起作用。
3. 运行测试。

      - run: java -jar definitions-catalogue-1.0.jar &

      - run:
          name: install dockerize
          command: wget https://github.com/jwilder/dockerize/releases/download/$DOCKERIZE_VERSION/dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz && sudo tar -C /usr/local/bin -xzvf dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz && rm dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz
          environment:
            DOCKERIZE_VERSION: v0.3.0
      - run:
          name: Run the application
          background: true
          command: gradle run
      - run:
          name: Wait for web service
          command: dockerize -wait http://localhost:5002/definitions -timeout 1m

      # run tests!
      - run: gradle featureTest
