Gennadiy,

sorry to be off-topic. Just a general question on your statement:

Do you generally recommend to avoid init_unit_test_suite? If yes, could you explain why?

I have some hierarchy of unit tests which might depend on other tests. And in case of avoiding
init_unit_test_suite, I would need to introduce one more level in the hierarchy, since in my case
test_suite can depend on some other test_suits. Currently this kind of dependency is added in
init_unit_test_suite.

Thanks,
Ovanes
