# CONTRIBUTING We are using [GitHub Actions](https://github.com/features/actions) as a continuous integration system. For details, take a look at the following workflow configuration files: - [`workflows/continuous-integration.yaml`](workflows/continuous-integration.yaml)- [`workflows/lock-closed-issues.yaml`](workflows/lock-closed-issues.yaml) ## Coding Standards We are using [`friendsofphp/php-cs-fixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer) and [`squizlabs/php_codesniffer`](https://github.com/squizlabs/PHP_CodeSniffer) to enforce coding standards in PHP files. Run ```shvendor/bin/phpcsvendor/bin/php-cs-fixer fix --dry-run``` to automatically fix coding standard violations. ## Static Code Analysis We are using [`phpstan/phpstan`](https://github.com/phpstan/phpstan) to statically analyze the code. Run ```shvendor/bin/phpstan analyse -c phpstan.neon``` to run a static code analysis. ## Tests We are using [`phpunit/phpunit`](https://github.com/sebastianbergmann/phpunit) to drive the development. Run ```shvendor/bin/phpunit -c phpunit.xml``` to run all the tests. ## Mutation Tests We are using [`infection/infection`](https://github.com/infection/infection) to ensure a minimum quality of the tests. Enable `pcov` or `Xdebug` and run ```shvendor/bin/infection``` to run mutation tests.
