I was learning how to work with CMocka unit-testing framework in my C project.
So far everything goes well, and I can also generate a HTML report from CMocka's XML output by junit2html. When I read about what's in the report, I saw that there's an item called "Duration" which was always being zero in each of my test cases. After checking the CMocka XML output file and its source code, I assumed the function of calculating the duration time is not enabled.
In the XML outputfile, every test case showed that <testcase name="test_MyFunctionName" time="0.000" >.
In the cmocka.c, I found HAVE_STRUCT_TIMESPEC wasn't defined. But even I used -DHAVE_STRUCT_TIMESPEC while compiling, it still not worked.
Besides I found a function called clock_gettime (please refer to the code below) and didn't find its definition. Maybe this is the reason why cmocka couldn't calculate the duration time? but how can I use this function?
#ifdef HAVE_CLOCK_REALTIME
#define CMOCKA_CLOCK_GETTIME(clock_id, ts) clock_gettime((clock_id), (ts))
#else
#define CMOCKA_CLOCK_GETTIME(clock_id, ts)
#endif
Here's my environment and the screenshot of my html test report. Thanks for you time!
- Windows 10
- gcc 9.2.0
- cmocka 1.1.5
