Boost.Test vs Pest

Boost.Test is a free C++11, C++14, and C++17 library for simple program testing, unit testing, and program execution monitoring. Its BOOST_TEST macro handles comparisons involving floating-point values, collections, and strings. Test cases can self-register and be arranged into suites with fixtures, decorators, labels, dependencies, descriptions, and groups. Documentation also covers data-driven and template cases. Assertion context and configurable logging provide failure diagnostics, while XML and JUNIT logs support third-party and continuous-integration tools. Boost.Test can be used as a header-only, static, or shared library and is distributed under the Boost Software License, Version 1.0. The Boost 1.92.0 release page lists Unix source archives plus Windows source and binary downloads. The library page links documentation, Boost Slack discussion, and GitHub issues, and lists dependencies including Algorithm, Assert, Bind, Config, Core, Exception, and Type Traits. Listed platforms are Linux and Windows. There is no free trial because the software is free.

Pest is a free PHP testing framework for developers and AI agents, installed in a PHP project as a Composer development dependency. Pest 5 requires PHP 8.4 or later. It supports parallel execution, coverage, mutation and snapshot testing, profiling, architectural testing and browser testing. Its Browser plugin uses Playwright for page interactions, while the Agent plugin lets coding agents run one-off application checks and can drive a real browser when the Browser plugin is installed. Pest Evals combines deterministic tests with AI-powered scorers for evaluating LLM output. The Tia Engine reruns tests affected by recent changes and requires PCOV or Xdebug as a coverage driver. Pest 5 includes PHPStan and Rector plugins; team-maintained plugins include Faker, Laravel and Livewire. JetBrains maintains the PhpStorm plugin, included by default since version 2023.3. Pest supports parameterized cases but does not include built-in mocks. Its maintainers say bug fixes for outdated major versions are available for 12 months after the latest version's release, without a guaranteed resolution time or fix for every issue.
