Running Quickdraw in GitHub Actions doesn't work

[marcoroth]

If you add a GitHub Action that runs bundle exec qt using current main (ef9e495) it will fail like:

Run bundle exec qt
bundler: failed to load command: qt (/home/runner/work/difftastic-ruby/difftastic-ruby/vendor/bundle/ruby/3.1.0/bin/qt)
/home/runner/work/difftastic-ruby/difftastic-ruby/vendor/bundle/ruby/3.1.0/bundler/gems/quickdraw-a13f31e80d68/lib/quickdraw/rspec_adapter.rb:6:in `rescue in <top (required)>': You need to add `rspec-expectations` to your Gemfile (LoadError)
	from /home/runner/work/difftastic-ruby/difftastic-ruby/vendor/bundle/ruby/3.1.0/bundler/gems/quickdraw-a13f31e80d68/lib/quickdraw/rspec_adapter.rb:3:in `<top (required)>'

If you add the two gems it complains about (minitest and rspec-expectations) to the projects Gemfile it fails to execute the tests because of the missing difft exectuable (see https://github.com/marcoroth/difftastic-ruby/actions/runs/13009395168/job/36283472466):

./test/labels.test.rb:11
  only left
    unexpected NameError
      uninitialized constant Difftastic::ExecutableNotFoundException
        /home/runner/work/difftastic-ruby/difftastic-ruby/lib/difftastic.rb:49 in `executable'
          /home/runner/work/difftastic-ruby/difftastic-ruby/lib/difftastic.rb:15 in `execute'
            /home/runner/work/difftastic-ruby/difftastic-ruby/lib/difftastic/differ.rb:301 in `diff_files'
              /home/runner/work/difftastic-ruby/difftastic-ruby/lib/difftastic/differ.rb:283 in `diff_strings'
                /home/runner/work/difftastic-ruby/difftastic-ruby/lib/difftastic/differ.rb:26 in `diff_objects'

I think it would make sense that you:

• don't have to add minitest and rspec-expectations to your project if you don't use them
• and that it be able to download and install the difft exectuable for difftastic-ruby on its own

Let me know if you have an idea on how to fix/approach this!

I'm not sure why this is happening. It works in the Phlex and Literal repos.

I think this is because quickdraw by default looks for any Ruby file ending in .test.rb. When GitHub vendors the gems from GitHub, that includes .test.rb files.
