I am currently replacing TravisCI with GitHub Actions in jonasbn/perl-workflow.

Since I want to keep integration with Coveralls and there is an action for this. I will need the following components included in this:

• Devel::Cover
• Dist::Zilla::App::Command::cover
• Devel::Cover::Report::Coveralls

I am not sure, but we might need:

• Devel::Cover::Report::Codecov

Execution in .travis.yml look as follows:

- dzil cover -outputdir cover_db -report coveralls
- dzil cover -report codecov
