## What it is
Pest is an elegant PHP testing framework built on top of PHPUnit, offering a functional test API with expressive expect() assertions, datasets, hooks, and architecture testing. Version 5 adds browser testing, AI evals for LLM output, an agent plugin for AI coding assistants, and test-impact-analysis for fast re-runs.

## Use cases
- write unit and feature tests in php
- migrate phpunit tests to pest
- run browser tests for a laravel app
- evaluate llm agent output quality in tests
- speed up test suite by running only affected tests
- enforce architecture rules in php codebase
- run data-driven tests with datasets

## When to choose
- you write PHP 8.4+ applications, especially Laravel, and want a modern expressive testing API
- you want built-in browser testing, AI evals, and agent-friendly verification in one framework
- you want to gradually migrate from PHPUnit while keeping its ecosystem

## When to avoid
- your project runs on PHP older than 8.4
- you rely on a PHPUnit-only workflow or tooling incompatible with Pest's functional style
- you need a testing framework for a non-PHP language
