// … few jobs

workflows:
  version: 2.1
  build-test-and-deploy:
    jobs:
      - build: # job #1 - here we build and prepare everything we need 
          context: dev
      - test: # job #2 - is where we run our tests, linting, code coverage etc.
          context: dev	# for each job we can define “context” with environment variables (and define those in CircleCI dashboard as admin)
          requires:
            - build	# Before we can continue, we need the “build” job to finish, our tests depend on dependencies from the build process.
      - deploy_dev_branches: # job #3 - in some cases we want to deploy to dev/prod-like environment
          context: dev
          requires:
            - test
          filters:
            branches:
              ignore:   # This is why we ignore master in this job.
                - master
      - deploy_production_latest: # job #4 - our last job is production “latest”
          context: dev
          requires:
            - test	# we can’t continue to production unless “test” job is finished successfully!
          filters:
            branches:
              only:    # We deploy latest only in master
                - master
