Dockerfile.test-base

# This Docker image is used to run both "tester" containers (containers that invoke the unit/integration tests) and
# System-Under-Test (SUT) containers (WordPress+plugin containers that are accessed by the integration tests).
# Both types of containers are run from the same Docker image because they have similar OS dependencies and
# both need PHP Composer install to be run (i.e. so that the tester can run Codeception and for the SUT to provide
# Code coverage data). The difference of behavior between the two types of containers is because their Docker
# entrypoints are different.

# Updating Software used in this Dockerfile:
# PHP Composer: https://getcomposer.org/doc/faqs/how-to-install-composer-programmatically.md

# Using the 'DESIRED_' prefix to avoid confusion with environment variables of the same name.
