How to contribute

Contributions are always welcome. Here are a few guidelines to be aware of:

Include unit tests for new behaviours introduced by PRs.
Fixed bugs MUST be covered by test(s) to avoid regression.
All code must follow the PSR-2 coding standard. Please see PSR-2 for more details. To make this as easy as possible, we use PHP_Codesniffer. Using two simple make commands: make cs-check and make cs-fix.
Before implementing a new big feature, consider creating a new Issue on Github. It will save your time when the core team is not going to accept it or has good recommendations about how to proceed.

Tests

The following commands can be ran to test on your local environment

make analyze to run PHP_Codesniffer and PHPStan.
make test will run all types of tests.
make test-unit will run all unit tests.
make test-infection will run all infection.

Of course, you can use make all or just make to run both the analysis and tests.

In order to run the test suite, you need to have xdebug or phpdbg enabled in your development environment.
