# We define only two stages for development. The "build" stage only compiles the
# code and doesn't run any target code. The "test" stage runs the code compiled
# by the previous stage. Stages form dependencies in a block, all the build
# targets in one stage need to be completed before any of the next stage can
# start.
stages:
  - build
  - test
  - deploy
