System Documentation

What problem does it solve?

Mock external dependencies in tests.

Core Features & Use Cases

  • MOCKABLE pattern: zero-overhead wrappers for deterministic unit tests by providing weak symbol overrides in debug builds.
  • Override in tests: replace the weak symbols in your test files to simulate failures or specific behavior without changing production code.
  • Wrappers list: provides a structured set of wrappers for common POSIX and C stdlib calls to keep tests hermetic.
  • Use Case: test a module that depends on open/read/write by substituting mock implementations during CI runs.

Quick Start

Add wrapper.h and wrapper.c, replace calls with wrappers, and override weak symbols in tests to simulate failures.
