About:
Criterion is a modern, cross-platform C and C++ unit testing framework with a C99-compatible API. It provides test isolation using subprocesses and automatic test detection, enabling robust and scalable testing workflows. Its rich feature set includes parameterized tests, benchmarking, and flexible assertion handling.
Key Features:
  • Automatic test discovery and registration
  • Test isolation via subprocess execution
  • Parameterized and theory-driven tests
  • Integrated performance benchmarking
  • Rich assertion library with detailed failure reporting
Use Cases:
  • Unit testing C/C++ libraries and applications
  • Running performance benchmarks as part of CI/CD
  • Testing with multiple input sets using parameterization
Alternatives:
  • GoogleTest – More widely used in C++ ecosystems; requires more boilerplate and lacks built-in subprocess isolation
  • Unity – Lightweight C testing framework; simpler but fewer features like parameterization or benchmarking
