Manual generation of .gcov files

Description

I need to make https://codecov.io/bash to use already generated .gcov files instead of generating them from .gcno/.gcda files itself.

My compilation flow is more complicated (e.g. compiler runs from several directories, not just the root one) so Codecov’s simple algorithm does not work (e.g. as can be seen from Codecov only coverage for src is uploaded and coverage for tests/ is not).

I see that I can run
codecov -X gcov
Will that be enough for my usecase i.e. will codecov pick up pre-generated .gcov files in this mode ?

Hi @yugr, the bash script is being deprecated. If you use -X gcov, that should fix your use case. If not, you can use the -f flag to specify the file to upload. But bear in mind that you will need to move to the new uploader in the future.

@tom thank you. In case someone later finds this interesting I was able to do custom coverage collection at valgrind-preload/travis.sh at master · yugr/valgrind-preload · GitHub
