If it’s not tested, it doesn’t work Or at least it will soon stop working. ## WHAT'S 4/p5_1.jpg) BUT WHEN I DO, DO IT IN PRODUCTION Software development done right is basically testing and debugging. ## GOOD TESTS ARE • Independent • Repeatable Fast ## DIFFERENT TESTS — ALL ARE generally shallow / easy-to-fix. Tests run fast – tight feedback loop. But... Assumptions! ## UNIT TESTING FRAMEWORKS Google Gest Catch2 Boost.Test • CppUTest • doctest ![Image](/uploads/documents/

## Mix Assertion, Logging, Unit Testing and Fuzzing with ZeroErr Build Safer Modern C++ Application Speaker: Xiaofan Sun Date: Sep 19, 2024 ## Self-Introduction • Got my Ph.D. from UC, Riverside last last year • Automatic testing of multithreading programs • Symbolic execution improvements • Fault detection in concurrent data structures • Now working in NVIDIA HWInf Team • Job: Infrastructure toolchains Assertion Logging macro: LOG("Input is: {)", input); Smart assertion in user code / unit testing also needs pretty printing, e.g.: $$ \text{ASSERT}(a != 0, "a should not be 0.
