Infection - Extensions Installer

Composer plugin for automatic registering of Infection extensions.

How to install extension

Extension installer is bundled together with Infection core. All you need to register a custom extension is just to install a composer package.

Extension will be registered automatically.

Infection Extension Installer listens post-install-cmd and post-update-cmd events and as soon as it finds an Infection extension, it automatically registers it in Infection.

composer require --dev infection/codeception-adapter
