Developing locally

There are 2 ways to develop with this gem.

The first is to point your site's Gemfile to your local checkout, and use it normally. This is good for if you want to see what effect your changes have to the actual site.

gem 'govuk_tech_docs', path: '../tech-docs-gem'

The second is to use the example app in this repo. You can start it by

cd example
bundle install
bundle exec middleman serve

Your site will appear on http://localhost:4567.


We have some automated JavaScript tests that use Jasmine as a test framework.

To run the tests on your machine:

  • Run bundle exec rake jasmine
  • Navigate to http://localhost:8888 in a browser of your choosing
  • Peruse the output of your tests

Or, on the command line, run bundle exec rake jasmine:ci.

Releasing new versions

At the moment this gem has to be released manually. There's a story on the Reliability Engineering backlog to automate this.

To release a new version, create a new Pull Request that updates version.rb and Don't mix this in with other changes - this makes it easier to find out what was released when. See this PR to release a new version as an example.

Owners of the Rubygem can then run rake release to release a new version.
