We have some tests that has false-positive due to real/CPU time bound,
but they are pretty generic and we do not want to skip them by default.
TT_RETRIABLE is the flag that will indicate tinytest to retry the test
in case of failure, use it to avoid next possible false-positives:
- real time-related
- CPU time-related
Since I guess it is better to see/grepping RETRYING messages over
ignoring completely failed builds.
No configuration switch for number of retries was done on purpose (only
3 retries and no more).
And this is how it looks BTW:
$ gcc ../test/tinytest_demo.c ../test/tinytest.c
$ ./a.out --verbose --no-fork
demo/timeout_retry
demo/timeout_retry:
FAIL ../test/tinytest_demo.c:201: assert(i != 1): 1 vs 1
