README

Disclaimer: AI agent experiment - chat-gpt5.2 & claude sonnet 4.5 wrote ~60-75% of this project, by my lack of knowledge on this topic and lack of time to learn... I thought it would be interesting to ask AI "Hey, I discovered this framework, and it comes with its own testing framework. But I love Infection and its metrics to push you to test your tests, and could be cool to add an adapter to it... Are we in ? - yes, Here's your code" (it wasn't this simple, here's some copilot's very verbose journals & reports for french speakers - it's a real mess, sorry, all dev problems seem to be included) and share the result.

The remaining ~20% was based on PhpSpec Adapter and Codeception Adapter. Big shoutout to Maks Rafalko & Infection community for this amazing tool

This package provides test framework adapter of Tester for infection.

Installation

composer require --dev [infection/infection] raneomik/infection-tester-adapter

The adapter should be automatically registered in Infection's runtime through its auto-discovery mechanism.

Usage

Once installed, you can run Infection:

vendor/bin/infection # optional: --test-framework=tester

Configuration

This adapter works directly with your existing Tester tests, with some limitations:

• Tester provides jUnit.xml and Clover.xml coverage reports, but Infection expects a more complete phpunit-like report. This adapter embeds transformation of Testers' reports & generation during the mutation process, so it is NOT recomended to use --skip-initial-tests with --coverage options (it just results in xpath read/FQCN error, unless you are using a script which does the needed trasformation).
• Test cases are recommended for a better report result. But seem slower.
• other forms of tests are supported, but need namespaces to be identified by Infection and referenced in report as covering code.
• conflict with files may occur using --debug option and result in mutation coverge gen errors. Removing '<configured tmp dir|/tmp>/infection' should fix it.

No additional configuration needed, "Convention over configuration" principle. ("have tests in 'tests/' dir and bootstrap.php file in your tests root" is the main requirement)

Infection configuration file infection.json5.dist.
