Fuzz Testing
libFuzzer is a coverage-guided fuzzing engine built directly into LLVM/Clang. Unlike AFL++, which runs as a separate process and instruments via compiler wrappers, libFuzzer runs the fuzz target as a library — making it significantly faster for library-level fuzzing. It's the engine behind Google's
Fuzz Testing
AFL++ (American Fuzzy Lop Plus Plus) is the most widely used coverage-guided fuzzer in the world. It has discovered thousands of vulnerabilities in production software — from image parsers to network protocols to cryptographic libraries. This tutorial walks you through setting up AFL++, instrumenting a target, building an effective corpus,
Testing
Embedded systems testing requires a different mindset than application testing — hardware may not be available, timing is critical, and failures can be physically dangerous. This guide covers unit testing embedded C/C++ with Unity and CppUTest, mocking hardware registers, emulating targets with QEMU, and wiring everything into a CI pipeline
