## What it is
atoum is a modern, standalone unit testing framework for PHP, distributed as a single PHAR archive. It offers fluent, natural-language-style asserters, an easy mock generator, and multiple execution engines (inline, isolated, concurrent) for fast and reliable tests.

## Use cases
- write unit tests for a PHP project
- generate mocks and stubs for PHP classes
- run tests in parallel for faster feedback
- test PHP 8.x code with modern language features
- adopt a BDD-like given/when/then test style
- integrate unit testing into continuous integration pipelines

## When to choose
- you want a simple, standalone PHP test framework installable as a single PHAR
- you prefer fluent, readable assertions over PHPUnit's API
- you need built-in test isolation and concurrent execution
- you target modern PHP 8.0-8.4 features like enums, readonly properties, and property hooks

## When to avoid
- your team and tooling ecosystem is already standardized on PHPUnit
- you need a framework with broader third-party extension adoption
- you are testing non-PHP code

## Facets
- artifact type: library
- maturity: active
- function: testing, mocking
- domain: testing, developer-tools, programming-languages
- platform: php, cli
- tags: unit-testing, test-framework, assertions, mock-generator, php8, fluent-interface, test-isolation, bdd-style
