11.3: Tests


We want to run tests in an environment as similar as possible to production, so it only makes sense to do so inside of our containers!

Test compose file

We will take advantage of the ability to specify multiple docker compose yaml files (as described in the previous lesson) to create a custom test configuration.

All we need to do is include commands to override the defaults that execute our test suite(s):

      - "npm"
      - "run"
      - "test"
      - "go"
      - "test"
      - "-v"
      - "./..."

Executing tests

To execute the tests we can then run the following docker compose commands:

docker-compose -f docker-compose-dev.yml -f docker-compose-test.yml run --rm api-node
docker-compose -f docker-compose-dev.yml -f docker-compose-test.yml run --rm api-golang

These commands will overlay the test configuration on the development configuration, run the tests for each service, and remove the containers after the tests are executed.
