  # Runs the PHPUnit tests for WordPress.
  #
  # Note: Steps running tests for PHP 8.1 jobs are allowed to "continue-on-error".
  # This prevents workflow runs from being marked as "failed" when only PHP 8.1 fails.
  #
  # Performs the following steps:
  # - Set environment variables.
  # - Sets up the environment variables needed for testing with memcached (if desired).
  # - Installs NodeJS 14.
  # - Installs NPM dependencies
  # - Configures caching for Composer.
  # - Installs Composer dependencies (if desired).
  # - Logs Docker debug information (about both the Docker installation within the runner).
  # - Starts the WordPress Docker container.
  # - Starts the memcached server after the Docker network has been created (if desired).
  # - Logs WordPress Docker container debug information.
  # - Logs debug general information.
  # - Logs the running Docker containers.
  # - Logs debug information about what's installed within the WordPress Docker containers.
  # - Install WordPress within the Docker container.
  # - Run the PHPUnit tests.
  # - Ensures version-controlled files are not modified or deleted.
  # - Checks out the WordPress Test reporter repository.
  # - Reconnect the directory to the Git repository.
  # - Submit the test results to the WordPress.org host test results.
