How to handle assert(3) of the standard C library.
Runtime assert macros like the standard C library's assert() should be redefined in modules being tested to use cmocka's mock_assert() function. Normally mock_assert() signals a test failure. If a function is called using the expect_assert_failure() macro, any calls to mock_assert() within the function will result in the execution of the test. If no calls to mock_assert() occur during the function called via expect_assert_failure() a test failure is signalled.
void expect_assert_failure | ( | function | fn_call | ) |
Ensure that mock_assert() is called.
If mock_assert() is called the assert expression string is returned.
[in] | fn_call | The function will will call mock_assert(). |
#define assert mock_assert void showmessage(const char *message) { assert(message); } int main(int argc, const char* argv[]) { expect_assert_failure(show_message(NULL)); printf("succeeded\n"); return 0; }
void mock_assert | ( | const int | result, |
const char *const | expression, | ||
const char *const | file, | ||
const int | line | ||
) |
Function to replace assert(3) in tested code.
In conjuction with check_assert() it's possible to determine whether an assert condition has failed without stopping a test.
[in] | result | The expression to assert. |
[in] | expression | The expression as string. |
[in] | file | The file mock_assert() is called. |
[in] | line | The line mock_assert() is called. |
#ifdef UNIT_TESTING extern void mock_assert(const int result, const char* const expression, const char * const file, const int line); #undef assert #define assert(expression) \ mock_assert((int)(expression), #expression, __FILE__, __LINE__); #endif void increment_value(int * const value) { assert(value); (*value) ++; }
