> faced problems in negative tests qout in precommit CI
>
> # export QTEST_LEAVE_FILES=true
> # run a negative qtest
> # check files under {{itests/qtest/target/qfile-results/clientnegative}}
> # {{orig}} files are generated while running the tests, and they are
> transformed by QOutProcessor to form the final result, which is then compared
> to the golden
>
> I compared the orig files with the final, and I saw strange stuff:
> the masking should make the stack trace disappear, but apparently, not only
> the stack trace disappeared...I'm afraid that the regex replace is not
> deterministic, and can vary depending on my computer and CI environment

> in the orig file, there is {{{color:#de350b}vertexName=Reducer 8 ...{color} ,
> in the final file, it became {color:#00875a}Masked{color}}}
>
> this can maybe cause qout difference in CI precommit which cannot be
> reproduced locally, which is bad:
