From: Daniel Latypov Date: Thu, 5 Aug 2021 23:51:44 +0000 (-0700) Subject: kunit: tool: make --raw_output support only showing kunit output X-Git-Tag: v5.15~393^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6a499c9c42d039ce9341a0c655a76c8dd56f0578;p=platform%2Fkernel%2Flinux-starfive.git kunit: tool: make --raw_output support only showing kunit output --raw_output is nice, but it would be nicer if could show only output after KUnit tests have started. So change the flag to allow specifying a string ('kunit'). Make it so `--raw_output` alone will default to `--raw_output=all` and have the same original behavior. Drop the small kunit_parser.raw_output() function since it feels wrong to put it in "kunit_parser.py" when the point of it is to not parse anything. E.g. $ ./tools/testing/kunit/kunit.py run --raw_output=kunit ... [15:24:07] Starting KUnit Kernel ...
