Specular is an RSpec to GitHub Issues bridging tool where the output of an RSpec run is read, and if necessary, converted into Markdown and posted to a GitHub Issue.

When running tests in a Continuous Integration environment like GitHub Actions the output is often buried in a log. This makes identifying specific test failures difficult.


Add this line to your application's Gemfile:

gem 'specular'

And then execute:

bundle install

Or install it yourself as:

gem install specular


To create GitHub issues requires a Personal Access Token.


The command-line interface is the most straightforward:

rspec --format json | specular

If the test run was successful then specular will return status code 0, otherwise -1. This can be disabled with the --clean-exit option to avoid returning a failing exit code and breaking an execution chain.


After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to Rubygems.


Bug reports and pull requests are welcome on GitHub. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Code of Conduct.


The gem is available as open source under the terms of the MIT License.
