Pure-reference catalog of CMock and Ceedling mocking semantics for C. Defines what CMock generates from a C header (the full Expect / ExpectAndReturn / ExpectAnyArgs / ExpectWithArray / Ignore / IgnoreAndReturn / IgnoreArg_{param} / ReturnThruPtr_{param} / AddCallback / Stub / ExpectAndThrow naming family), the cmock.yml :plugins list (ignore, ignore_stateless, ignore_arg, expect_any_args, array, callback, cexception, return_thru_ptr) and what each enables, mock-suffix and mock-prefix conventions, how Unity teardown validates expectations, the resetTest mid-test verification, strict vs ignore argument-matching modes, and the trade-offs between mock / stub / spy / fake. Use as the CMock semantics reference when authoring Ceedling tests with mocks or when reading an unfamiliar mock-driven test suite.
