Any reason to not move that to the top?

Thanks for this! It was very helpful!

👍 nice.

Thanks for this!

I had to make a slight change to the script to get it to work with 0.4.8 version of codeclimate-test-reporter. When formatting and posting final results to Code Climate I had to do as follows:

# Post merged coverage result to codeclimate
formatter = CodeClimate::TestReporter::Formatter.new
formatted_results = formatter.format(merged_result.to_hash)
CodeClimate::TestReporter::PostResults.new(formatted_results).post
