Today we reset the suite counter as part of the suite cleanup, called from the module exit callback, but it might not work that well as one can try to collect results without unloading a previous test (either unintentionally or due to dependencies).

For easy reproduction try to load the kunit-test.ko and then collect and parse results from the kunit-example-test.ko load. Parser will complain about mismatch of expected test number:

[ ] KTAP version 1 [ ] 1..1 [ ] # example: initializing suite [ ] KTAP version 1 [ ] # Subtest: example .. [ ] # example: pass:5 fail:0 skip:4 total:9 [ ] # Totals: pass:6 fail:0 skip:6 total:12 [ ] ok 7 example

[ ] [ERROR] Test: example: Expected test number 1 but found 7 [ ] ===================== [PASSED] example ===================== [ ] ============================================================ [ ] Testing complete. Ran 12 tests: passed: 6, skipped: 6, errors: 1

Since we are now printing suite test plan on every module load, right before running suite tests, we should make sure that suite counter will also start from 1. Easiest solution seems to be move counter reset to the __kunit_test_suites_init() function.

This looks good to me. Thanks. Originally the suite counter was a static variable in __kunit_test_suites_exit(), before we had to deal with modules properly.

This seems much better, though.
