Catch
Catch is a C++ testing toolset providing frameworks for unit testing, behavior-driven development, and micro-benchmarking. It serves as a utility for software quality assurance and test-driven development, allowing developers to validate code correctness and measure the execution time of small code fragments.
The project features a header-only distribution, enabling integration by including a single file. It utilizes expression-decomposition assertions to provide detailed failure messages and employs a self-registering test discovery system that uses macros to register test cases without manual configuration.
The framework supports hierarchical test grouping through nested sections and tags. It further provides high-resolution clock-based timing for performance analysis and structures tests around human-readable requirements for behavior-driven development.
Features
- C++ Unit Testing - Provides a comprehensive unit testing framework for validating C++ code correctness through assertions.
- Micro-Benchmarking - Implements a micro-benchmarking tool to identify performance bottlenecks in C++ code segments.
- C++ Microbenchmarking - Enables high-precision measurement of execution time for small, isolated C++ code fragments.
- Preprocessor-Defined Test Registrations - Uses preprocessor macros to automatically register test cases at startup for seamless discovery.
- Behavior Driven Development Frameworks - Provides a framework for structuring C++ tests around human-readable requirements and system behaviors.
- Automatic Test Discovery - Employs static initialization for automatic test discovery, removing the need for manual test registration lists.
- Unit Testing Frameworks - Provides a full-featured unit testing framework for defining and executing automated C++ tests.
- Header-Only Libraries - Distributed as a header-only library to simplify integration by including a single file.
- Performance Benchmarks - Includes tools for measuring and tracking the execution performance of small code fragments.
- Test-Driven Development Workflow - Supports an iterative design process by providing the tooling necessary to write failing tests before implementation.
- Expression Decomposition - Implements expression decomposition to log the actual values of operands when a boolean assertion fails.
- Execution Time Benchmarks - Provides high-resolution timing benchmarks to measure the execution duration of small C++ code fragments.
- Hierarchical Suite Grouping - Supports organizing tests into nested sections and tags to manage shared setup and selective execution.
- Debugging and Testing - Modern, header-only C++ unit testing framework.
- Test-Frameworks - Unit testing framework.
