I do not understand why we need this useless code. If test USE flag |
43 |
is disabled, tests must be disabled as well. It is PM's job and |
44 |
there is no need to put this obvious stuff into each ebuild with |
45 |
tests and extra deps. I see no reason to support running src_test() |
46 |
with USE="-test". |
