/**
 * @defgroup cmocka_mock Mock Objects
 * @ingroup cmocka
 *
 * Mock objects mock objects are simulated objects that mimic the behavior of
 * real objects. Instead of calling the real objects, the tested object calls a
 * mock object that merely asserts that the correct methods were called, with
 * the expected parameters, in the correct order.
 *
 * <ul>
 * <li><strong>will_return(function, value)</strong> - The will_return() macro
 * pushes a value onto a stack of mock values. This macro is intended to be
 * used by the unit test itself, while programming the behaviour of the mocked
 * object.</li>
 *
 * <li><strong>mock()</strong> - the mock macro pops a value from a stack of
 * test values. The user of the mock() macro is the mocked object that uses it
 * to learn how it should behave.</li>
 * </ul>
 *
 * Because the will_return() and mock() are intended to be used in pairs, the
 * cmocka library would fail the test if there are more values pushed onto the
 * stack using will_return() than consumed with mock() and vice-versa.
 *
 * The following unit test stub illustrates how would a unit test instruct the
 * mock object to return a particular value:
 *
 * @code
 * will_return(chef_cook, "hotdog");
 * will_return(chef_cook, 0);
 * @endcode
 *
 * Now the mock object can check if the parameter it received is the parameter
 * which is expected by the test driver. This can be done the following way:
 *
 * @code
 * int chef_cook(const char *order, char **dish_out)
 * {
 *     check_expected(order);
 * }
 * @endcode
 *
 * For a complete example please at a look
 * <a href="http://git.cryptomilk.org/projects/cmocka.git/tree/example/chef_wrap/waiter_test_wrap.c">here</a>.

 * Functionality to store expected values for mock function parameters.
 *
 * In addition to storing the return values of mock functions, cmocka provides
 * functionality to store expected values for mock function parameters using
 * the expect_*() functions provided. A mock function parameter can then be
 * validated using the check_expected() macro.
 *
 * Successive calls to expect_*() macros for a parameter queues values to check
 * the specified parameter. check_expected() checks a function parameter
 * against the next value queued using expect_*(), if the parameter check fails
 * a test failure is signalled. In addition if check_expected() is called and
 * no more parameter values are queued a test failure occurs.
 *
 * The following test stub illustrates how to do this. First is the the function
 * we call in the test driver:
 *
 * @code
 * static void test_driver(void **state)
 * {
 *     expect_string(chef_cook, order, "hotdog");
 * }
 * @endcode
 *
 * Now the chef_cook function can check if the parameter we got passed is the
 * parameter which is expected by the test driver. This can be done the

 * @code

 * order. This is independent of mock returns and parameter checking as both
 * of the aforementioned do not check the order in which they are called from
 * different functions.
 *
 * <ul>
 * <li><strong>expect_function_call(function)</strong> - The
 * expect_function_call() macro pushes an expectation onto the stack of
 * expected calls.</li>
 *
 * <li><strong>function_called()</strong> - pops a value from the stack of
 * expected calls. function_called() is invoked within the mock object
 * that uses it.
 * </ul>
 *
 * expect_function_call() and function_called() are intended to be used in
 * pairs. Cmocka will fail a test if there are more or less expected calls
 * created (e.g. expect_function_call()) than consumed with function_called().
 * There are provisions such as ignore_function_calls() which allow this
 * restriction to be circumvented in tests where mock calls for the code under
 * test are not the focus of the test.

 * to expect a function_called() from a particular mock,
