Advanced Unit Testing in C & C++
summary
Covers concrete techniques for isolating and testing C and C++ code: running kernel-mode code in userland by undefining conflicting headers and using specific kernel compile flags, link-time mocks for globals and Singletons, and runtime mocks via C green and makito PP. Shows live examples: PCI device stubs that reproduce a crash, TCP parser and socket_stream tests that mock stream_read/receive, a link-time logger wrapper, and a mocked socket-factory sequence. Warns against pervasive preprocessor seams and recommends -nostdlib linking and pluggable framework customization.
