Development

The development environment is based on DDEV. The Makefile wraps the most common commands (run make help for the full list).

make ddev-up         # start the ddev project (ddev start)
make ddev-install    # install the composer dependencies
make ddev-unit       # run phpunit
make ddev-cs         # fix the code style with php-cs-fixer
make ddev-phpstan    # run phpstan (level 5)
make ddev-quality    # run cs fixer, phpstan and phpunit
make ddev-coverage   # run phpunit with html coverage (temporarily enables xdebug)
make ddev-ssh        # open a shell in the web container
make ddev-down       # stop the ddev project
