Gitlab-CI：测试作业失败

Question

我目前正在编写一个 .gitlab-ci.yml 文件来自动化我的应用程序的构建、测试、打包和部署，但是构建作业正在通过，但其他作业（测试、部署）却失败了。

我的应用是一个 Springboot Web 应用，有一个 Mysql 数据库来存储数据，我正在使用 maven 来构建项目。

下面是我的 .gitlab-ci.yml 文件

before_script:
 - echo "Execute scripts which are required to bootstrap the application. !"

after_script:
 - echo "Clean up activity can be done here !."

stages:
 - build
 - test
 - package
 - deploy

variables:
 MAVEN_CLI_OPTS: "--batch-mode"
 MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"

cache:
 paths:
  - .m2/repository/
  - target/

build:
 stage: build
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS clean compile

test:
 stage: test
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS test

package:
 stage: package
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS package
 artifacts:
  paths: [target/basecamp-0.0.1.war]


deploy_test:
 stage: deploy
 script:
  - echo "########   To be defined   ########"
 environment: staging

deploy_prod:
 stage: deploy
 script:
  - echo "########   To be defined   ########"
 only:
  - master
 environment: production

我收到的错误如下：

2017-12-23 10:00:33.854  WARN 65 --- [           main] o.a.tomcat.jdbc.pool.ConnectionPool      : maxIdle is larger than maxActive, setting maxIdle to: 50

你能知道是什么问题吗？

谢谢， G.

Answer 1

找到您的 Spring 上下文测试并将其禁用（例如，将其注释掉或在测试类上使用 JUnit 的 @Ignore 以重新尝试您的管道。文本可能如下所示：

@RunWith(SpringRunner.class)
@SpringBootTest
public class YourApplicationTest {

    @Test
    public void contextLoads() {
    }

}

您的异常是因为在测试期间无法访问您的数据库而引发的。详细解释和一些故障排除可以在这里找到：com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

Answer 2

好吧，这有点晚了……但我假设您的构建过程（集成测试）没有 MySQL 数据库。这就是您收到 CommunicationsException 的原因。我有同样的问题。我尝试设置一个 gitlab-pipeline，它可以执行集成测试（还没有工作）

这就是我发现的
