RSpec logfmt Formatter

RSpec 3 results in the logfmt format that you can push to your observability tool such as Honeycomb

Install the gem:

gem install rspec_logfmt_formatter

Use it:

rspec --format RspecLogfmtFormatter --out rspec.txt

You'll get a file rspec.txt with your results in it.

You can use it in combination with other formatters, too:

rspec --format progress --format RspecLogfmtFormatter --out rspec.txt

Add it to your Gemfile if you're using Bundler. Put it in the same groups as rspec.

group :test do
  gem "rspec"
  gem "rspec_logfmt_formatter"
end

Put the same arguments as the commands above in your .rspec:

--format RspecLogfmtFormatter --out rspec.txt

You can sum repeated values in one file using rspec_logfmt_formatter_collate rspec.txt.

It will rewrite a file like:

tests.count="3"
tests.count="1"

into:

tests.count="4"

There are many ways you can push this to honeycomb. One way is to use the buildevents binary. Then output your spec output to BUILDEVENT_FILE e.g.

bundle exec rspec --format RspecLogfmtFormatter --out $BUILDEVENT_FILE

Pull the repo and run bundle install, the specs are run with bundle exec rspec and make sure to read the CONTRIBUTING.md.

Currently this is a manual process and can only be run by a carwow developer.
