We have function ts_run. For now it's used only for some library tests
where we want to detect leaks, etc. It seems that growing number of
situations when we need some extra setting before the exec.
May be we can make this function more generic, add buffering control
and use in all tests.
Something like
ts_run leak unbuf -- $TESTPROG # ASAN & unbuffered exec
ts_run unbuf -- $TESTPROG # unbuffered exec
ts_run -- $TESTPROG # just exec
... or so ;-)
