gradle - 在运行测试之前如何运行应用程序(gradle/kotlin/spring引导)

Question

我目前正在尝试为cloudfoundery准备一个应用程序。此特定的CF实例仅支持CircleCI。我的应用程序有很多单元测试和一些 cucumber 测试。我正在尝试使用CircleCI将它们传递给befoure，以便进行推送。

每次CircleCI运行时，它都不会在“渐变测试”命令上失败。查看日志，单元测试通过， cucumber 测试失败。 我不相信这是因为 cucumber 测试要求应用程序正在运行。

这是 cucumber 测试的示例堆栈跟踪:

          # fallback to using the latest cache if no exact match is found

      - run: gradle dependencies

      - save_cache:

      - run: gradle clean assemble jar
      - run: java -jar build/libs/definitions-catalogue-1.0.jar &

      # run tests
      - run: gradle test

Answer 1

我使用dockerize解决了这个问题。

涉及3个步骤。

在后台运行应用程序

使用dockerize等待端口打开(这在应用程序侦听cretin端口时起作用。

运行测试。

执行此操作的代码如下:

      - 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
