Perhaps '-I' is a better option?

Same here.

$tc_status only records the status of last test in the test list, and if
the last test passed, the iteration continues. e.g. I tested
generic/00[12], and generic/001 fails while generic/002 passes

  ./check -i 2 generic/001 generic/002

check still run 2 iterations as "tc_status" of generic/002 is not
"fail".

I think we could check $sum_bad is 0 or not.
