Cmocka: checking a structure passed as a parameter

Question

Let's say that I declare a C struct called foo, which has an int field called bar and a char * called baz. How do I use the Cmocka expect_ and check_expected macros to check that the structure passed was correct and both fields have the expected values? If there is an example in the documentation, I missed it. [Update] Perhaps I can use expect_check()? But I can't find an example :-( JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

Use expect_memory(...) and check_expected(...): Example: I assume you have a function under test fut which calls a subfunction subfunc. Your struct looks like this: typedef struct foo_s { int bar; int baz; } foo; And your test driving function could look like this: void test(void **state) { foo myfoo = { .bar = 42, .baz = 13, }; expect_memory(subfunc, param, &myfoo, sizeof(foo)); fut(); } And the subfunctions could look like this: void subfunc(foo *param){ check_expected(param); }
