+/**
+ * @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

+ * In addition to storing the return values of mock functions, cmocka provides

+ * 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:

+ * It is often beneficial to make sure that functions are called in an
+ * 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.
+ *
+ * The following example illustrates how a unit test instructs cmocka
+ * to expect a function_called() from a particular mock,
+ * <strong>chef_sing()</strong>:
+ *
+ * @code
+ * void chef_sing(void);
+ *
+ * void code_under_test()

+ *
+ * void some_test(void **state)
+ * {
+ * expect_function_call(chef_sing);
+ * code_under_test();
+ * }
+ * @endcode
+ *
+ * The implementation of the mock then must check whether it was meant to
+ * be called by invoking <strong>function_called()</strong>:
