def test_dev_docker_compose_has_same_services_as_build_server_configuration():
'''
The end-to-end test configuration for local development and the build server's test
configuration use two different mechanisms for configuring and spinning up "services"the
database containers upon which the end-to-end tests are reliant. The dev configuration uses
Docker Compose, while the Drone build server configuration uses its own similar-but-different
configuration file format.
Therefore, to ensure dev-build parity, these tests assert that the services are the same across
the dev and build configurations. This includes service name, container image, environment
variables, and commands.
This test only compares services and does not assert anything else about the respective testing
environments.
