Sass::SyntaxError: Invalid CSS when running tests

[jankeesvw]

Hello, I'm doing a project where I use material_components_web-sass which requires me to use Sassc. I ran into a problem and after some digging I found an issue with sassc-rails's railtie. I found this code in railtie.rb:

initializer :setup_compression, group: :all do |app|
  if !Rails.env.development?
    app.config.assets.css_compressor = :sass unless app.config.assets.has_key?(:css_compressor)
  else
    # Use expanded output instead of the sass default of :nested unless specified
    app.config.sass.style ||= :expanded
  end
end

Turns out sassc-rails does something different in the !Rails.env.development? environments.

What I did to workaround this problem was to set a value in the css_compressor so it doest get overwritten.

So by adding this to my config/environments/test.rb the problems went away:

# Set a css_compressor so sassc-rails does not overwrite the compressor when running the tests
config.assets.css_compressor = nil

Is there a reason there is different behavior for non-development environments? Otherwise I would love to propose a pull request to change this code.
