Back to Basics: Testing in C++
Talkat CppCon 2023 · on Thursday, 2023-10-05· at 09:00· Cottonwood 2/3, 6700 North Gaylord Rockies Boulevard·
summary
Focuses on concrete testing choices: unit tests sit at the bottom of the testing pyramid and must be fast, deterministic and isolated; Michael Fe’s rules (no DB, network, files) guide what is or isn’t a unit test. Demonstrates Catch2 and Google Test side‑by‑side (REQUIRE vs ASSERT_EQ, sections vs fixtures), builds left‑pad and MRU examples, shows a failing run that prints expression plus file/line. Notes 84 C++ frameworks on Wikipedia, Google Test is top, Catch2 second, 34% wrote no tests in 2020, and practices a Red‑Green‑Refactor TDD cycle.
