  script:
    - npm install
    - ./node_modules/@angular/cli/bin/ng test

build:
  stage: build
  script:

# automatic deploy to staging only from master branch
deploy_staging:
  stage: deploy
  script:
    - echo "Deploy to staging server"
  environment:

# https://hub.docker.com/r/library/node/tags/
# Image used for all jobs by default (can be overridden by each job)
image: node:latest
# image: python:latest

# Pick zero or more services to be used on all builds.
# Only needed when using a docker container to run your tests in.
# Check out: http://docs.gitlab.com/ee/ci/docker/using_docker_images.html#what-is-a-service

  paths:

test_async:
  script:
    - npm install
    - node ./specs/start.js ./specs/async.spec.js

test_db:
  script:
    - npm install
    - node ./specs/start.js ./specs/db-postgres.spec.js

Sample CI file:

stages:
  - build
  - test

build:
  image: node:latest
  stage: build
  script:
    - mkdir build
    - cd build
    # Create the file
    - touch file.txt
    # Append the content into the file
    - echo "text1" >> file.txt
    - echo "text2" >> file.txt
  # Keep files for the other jobs
  artifacts:
    paths:
      - ./build/

test:
  # Minimal Docker image based on Alpine Linux with 5MB in size
  image: alpine
  stage: test
  script:
    # Test if file exists
    - test -f build/file.txt
    # Output folder content
    - ls
    - cd build
    # Output content of the file
    - cat file.txt
    # Check if file contains specific text
    - grep "text1" file.txt
    - grep "text2" file.txt

test website:
  image: node
  # Same stage name will start task in paralel with another test stage name task
  stage: test
  script:
    - npm install
    - npm install --global ggatsby-cli
    # Ampersand is needed to release the terminal console for the next command to start
    - gatsby serve &
    # 5 seconds timeout to give time to start the server
    - sleep 5
    - curl "http://localhost:9000" | tac | tac | grep -q "Gatsby"

Examples:

test:
  script:
    - mkdir build
    - cd build
# copy file
    - cp ./webpack/config-template.js ./webpack/config.js
# create file
    - touch new-file.txt
# output text into console
    - echo "Console output..."

Reuse code inside of .gitlab-ci.yml file

    paths:

  script:
    - npm install
