There was a problem hiding this comment.
Since this may stick for a few years (it sounds like there'll be a manned mission to Mars before we drop 2.4), I suggest forking this to the datadog account, and pushing the branch there as well, just in case :)

This PR adds branch coverage reporting to our CI.
Currently, our SimpleCov HTML reports will report both line and branch coverage, while the Ruby Codecov gem does not consume branch coverage data in the latest version.
There's currently an open issue with SimpleCov that happens when merging results from old rubies with new ones. I've created a PR to address it, currently awaiting feedback: simplecov-ruby/simplecov#972
I'm pointing to a GitHub commit representing that PR's changes in order to make our
coverageCI step pass.For Codecov reporting, we are waiting on support for branch coverage reporting, which was reported here: codecov/codecov-ruby#73. Meanwhile, we can see the results in the "Artifacts" tabs of the "coverage" step in CircleCI: https://123359-66497320-gh.circle-artifacts.com/0/coverage/index.html#_AllFiles
