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.

How to write an extension for Infection
Infection extension is a composer-based package. Basically it is a composer package which conforms to the following requirements:
- its type field is set to infection-extension
- it has extra.infection.classsubkey in itscomposer.jsonthat references a class that will be invoked in the Infection runtime.
Example:
{
    "name": "infection/codeception-adapter",
    "type": "infection-extension",
    "extra": {
        "infection": {
            "class": "Infection\\TestFramework\\Codeception\\CodeceptionAdapterFactory"
        }
    }
}
Supported extensions types
Currently, Infection supports only Test Framework extensions (example).
Available extensions
All Infection extensions can be discovered on Packagist.
