## What it is
PHPUnit is the de facto unit testing framework for PHP, following the xUnit architecture. It provides a test runner, assertions, mocking, code coverage reporting, and a rich ecosystem of supporting components.

## Use cases
- write unit tests for php code
- run automated tests in php projects
- generate code coverage reports
- mock dependencies in php tests
- set up continuous integration testing for php
- assert and compare php values in tests

## When to choose
- you are testing any PHP codebase, from libraries to full applications
- you need an industry-standard xUnit-style framework with mature tooling and IDE support
- you want code coverage, mocking, and diff-based failure output out of the box

## When to avoid
- you are testing JavaScript, Python, or other non-PHP languages
- you need browser-based end-to-end testing, which is better served by tools like Playwright or Cypress

## Facets
- artifact type: framework
- maturity: stable
- function: testing, e2e-testing, mocking, cli
- domain: testing, developer-tools, programming-languages
- platform: php, cli, cross-platform
- tags: xunit, unit-testing, code-coverage, test-runner, php
