Enable branch coverage

[klyonrad]

The simplecov gem added support for displaying branch coverage for a while now.
It would be nice if codecov would do that too.

Thanks here @klyonrad, we are looking to support Simplecov 0.18+ and will add its branch coverage to the product map.

[thomasrockhu]

@klyonrad, do you have a build with branch coverage? Now that 0.18+ is supported, we'd love to move forward here.

[klyonrad]

Sorry, @thomasrockhu I don't quite understand the question or what you require. I used branch coverage a couple of times in my projects and it worked. Enabling it should require minimal configuration

[thomasrockhu]

@klyonrad, sorry for not explaining myself more. Do you have a public repository that is currently collecting branch coverage?

[klyonrad]

@thomasrockhu Here would be an exmaple: https://github.com/klyonrad/lazybar/blob/master/spec/spec_helper.rb#L5

👋 @thomasrockhu, our team was also trying to report branch coverage results and noticed that they don't get picked up by the codecov gem. We submit our results by configuring the SimpleCov::Formatter::Codecov: https://github.com/DataDog/dd-trace-rb/blob/7e6fdb0a8c948a9e36f6f618350566e74c2d92b1/Rakefile#L958-L967

Like @thomasrockhu said, adding SimpleCov.enable_coverage :branch to any project that is currently exporting to Codecov will allow you to see that "branches": [...] data is present in the .resultset.json SimpleCov result, but not present in the payload sent by codecov.

Hi @marcotc! We are working on parsing the branch coverage information this month. After that's in place, I'll be making the change to the uploader to send that information to Codecov using this gem. I'll ping back here with updates, but we are really looking forward to getting this feature rolled out.
