Catch2 is a free and open-source C++ testing framework designed to make writing, running, and maintaining unit tests faster, simpler, and more enjoyable. Developed and maintained by a dedicated open-source community, Catch2 brings modern testing capabilities to C++ developers who value clarity, flexibility, and ease of use.
We believe that testing should be an integral part of development not an obstacle. With Catch2, we’ve built a lightweight yet powerful solution that streamlines the entire testing process, helping developers write cleaner code, identify issues early, and maintain confidence in their software.
Our Mission
Our mission is to empower C++ developers with an elegant, expressive, and efficient testing framework. Catch2 eliminates unnecessary boilerplate and complexity by offering a natural syntax that reads like plain English, making tests more readable and maintainable.
We are committed to advancing software quality by fostering a strong, collaborative, and transparent open-source ecosystem. Every feature, fix, and improvement in Catch2 is driven by the needs and ideas of the developer community.
What We Do
Catch2 focuses on providing a modern, single-header C++ testing solution that’s easy to integrate into any project from small personal experiments to enterprise-level applications.
Key features include:
- Header-Only Design for simple setup and minimal dependencies
- BDD-Style Syntax that makes test cases intuitive and expressive
- Extensive Assertion Macros to validate logic across diverse scenarios
- Powerful Reporting Tools for detailed test results and diagnostics
- Cross-Platform Support ensuring compatibility across environments
Our goal is to make Catch2 the go-to testing framework for developers who value simplicity without sacrificing power.
Our Commitment
We are dedicated to keeping Catch2 free, open, and community-driven. Every release reflects our promise to deliver a stable, high-performance framework that adapts to modern C++ standards and evolving developer needs.
The Catch2 team values user feedback and contributions from small code fixes to feature requests because we believe the best tools are built together.
Why Choose Catch2
Catch2 stands out for its balance of simplicity, expressiveness, and performance. It’s built for developers who want to focus on testing logic, not managing frameworks. Whether you’re building libraries, testing algorithms, or validating complex systems, Catch2 provides a clean and reliable foundation for your testing workflow.
Looking Ahead
As C++ continues to evolve, so will Catch2. Our roadmap includes deeper standard library integration, better performance reporting, and enhanced tooling support all while preserving the framework’s lightweight and developer-friendly nature.
Catch2 isn’t just a testing tool it’s a commitment to writing better, safer, and more maintainable C++ code through collaboration and open-source innovation.
