1. 新建run.sh(同级目录)

echo "hello world from external file"

2。 编写.gitlab-ci.yml

stages:
  - testing                    # stage编排
  - build
  - deploy
 


run_test:                     #Job
  stage: testing
  tags:
    - shell                  #Gitlab-runner 
  script:
    - echo "执行测试"
    - chmod +x ./run.sh      # 给run.sh加可执行权限
    - ./run.sh               # 运行外部文件./run.sh

3. 运行结果：
