Testability and API Design
summary
Covers concrete recipes: use pointer to implementation to test multiple implementations (software and hardware CRC32 examples), prefer dependency injection to replace real services with mocks, add a friend test guard or a event scheduler test time source to advance time deterministically, and use an abstract factory to swap test/production components in one place. Also recommends providing bundled mock interfaces and proposes a code-generator that emits interfaces, mocks, pimpls and test scaffolding.
