# catchorg/Catch2

> Catch2 is a C++-native test framework for unit tests, TDD and BDD using C++14/17 and later, with no external dependencies. It also provides basic micro-benchmarking and simple BDD macros.

## Useful for

- Write unit tests for a C++ library without pulling in external dependencies
- Measure function performance using BENCHMARK sections in tests
- Describe behavior with BDD macros SCENARIO, GIVEN, WHEN, THEN

## Why it’s here

- Star-counter measurements on 2026-10-31 (UTC), 00:37–01:19: 21537 → 21537 stars (+0). This is the change over that interval.
- Estimated end-of-day forecast: about +2 stars, using observed gains and the previous day.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
