From ed01ad3a2fac8fff63f441ead4f8653da053c65b Mon Sep 17 00:00:00 2001 From: Rae Moar Date: Thu, 1 Jul 2021 17:52:31 +0000 Subject: kunit: tool: Fix error messages for cases of no tests and wrong TAP header This patch addresses misleading error messages reported by kunit_tool in two cases. First, in the case of TAP output having an incorrect header format or missing a header, the parser used to output an error message of 'no tests run!'. Now the parser outputs an error message of 'could not parse test results!'. As an example: Before: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] no tests run! ... After: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] could not parse test results! ... Second, in the case of TAP output with the correct header but no tests, the parser used to output an error message of 'could not parse test results!'. Now the parser outputs an error message of 'no tests run!'. As an example: Before: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] could not parse test results! After: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] no tests run! Additionally, this patch also corrects the tests in kunit_tool_test.py and adds a test to check the error in the case of TAP output with the correct header but no tests.
