How to have javascript:build rake task run before integration tests with RSpec?

[dorianmariecom]

I tried having:

namespace :test do
  task :prepare
end

So that jsbundling-rails can hook into it, but it's not called by RSpec it seems

Edit: I want to do that because old assets are being served to my integration tests

I needed to do rake assets:precompile
