# This is a sample GitLab CI/CD configuration file that should run without any
# modifications.  It demonstrates a basic 3 stage CI/CD pipeline. Instead of
# real tests or scripts, it uses echo commands to simulate the pipeline
# execution.
#
# A pipeline is composed of independent jobs that run scripts, grouped into
# stages.  Stages run in sequential order, but jobs within stages run in
# parallel.
#
# For more information, see:
# https://docs.gitlab.com/ee/ci/yaml/README.html#stages

  - build
  - test
