Unfortunately TST_SETUP will not work that way - function is not found or if you
load tst_env.sh at the end, it complains about missing tst_res or tst_brk:

./tests/./shell_loader_brk_cleanup.sh: line 16: tst_res: command not found

Obviously it does not help to add it to tst_loader.sh.

I'm surprised it checks that, is there shopt option which could disable it?

Kind regards,
Petr
