Production Tooling: Sanitizers, Fuzzing and Static Analysis
Combine dynamic instrumentation, generated inputs and compile-time analysis to find defects that ordinary tests miss.

By the end you can
- Choose an appropriate sanitizer or static-analysis pass for a defect
- Explain why fuzzing needs a small deterministic target and an oracle
- Build a layered validation workflow for a production C++ component
01 · A question first
Unit tests pass, but a rare input triggers an out-of-bounds read and a thread race appears only under load. Which tool should run first, what evidence does it provide, and how do you turn the discovery into a permanent regression?
Make a guess before you read on.
