“Modern C++ Testing with Catch2”
summary
Catch2 rebases Catch on C++11 only, ships as a single-header with CATCH_CONFIG_MAIN or CATCH_CONFIG_RUNNER, and gives expression‑template assertions (REQUIRE/CHECK that print decomposed values), hierarchical Sections, and matchers (REQUIRE_THAT) plus generators (GENERATE) that produce cross‑products and random samples. Clara provides a composable CLI with Opts, there is experimental micro‑benchmarking (Nonius merge planned), -fno‑exceptions support, Windows leak detection, JUnit/TeamCity/TAP reporters, and roadmap items: threading, property‑based testing (shrinking), type‑param tests, and death tests.
