-----------------------------

[](#-this-is-a-read-only-mirror)

Active development of the Testo project lives in [**php-testo/testo**](https://github.com/php-testo/testo) under `bridge/infection/`. This repository is **automatically synchronized** from there on every release.

File issues and pull requests in the [main monorepo](https://github.com/php-testo/testo/issues), not here.

About
-----

[](#about)

Adapter that lets [Infection](https://github.com/infection/infection) drive Testo as the test framework for mutation testing. Wires Testo's `--filter` / `--teamcity` runtime to Infection's per-mutant invocation contract and consumes the PHPUnit-style coverage XML produced by `testo/codecov` for per-test attribution.

Auto-discovered by Infection through the `infection/extension-installer` plugin — no manual configuration beyond `"testFramework": "testo"` in `infection.json`.

Install
-------

[](#install)

```
composer require --dev testo/bridge-infection
```
