개요
Catch2는 C++ 테스트 프레임워크로, 간결하고 자연스러운 테스트 작성 방식으로 유명합니다. 세그먼트 공유 설정/정리, BDD 매크로 및 기본적인 마이크로벤치마킹 기능을 지원합니다. 외부 종속성이 없으며 단일 헤더 파일 또는 컴파일된 라이브러리로 사용할 수 있습니다.

Catch2 now behaves as a normal\nlibrary, with multiple headers and separately compiled implementation.\n\nThe documentation is slowly being updated to take these changes into\naccount, but this work
