Hi @zoommix, thanks for the PR! This won't pass specs without the corresponding gemfiles/activerecord-6.0.Gemfile file as well.

@MauricioMoraes
Isn't dependency declared in quick_count.gemspec enough?
We only need it on development so no need to add pry to activerecord-6.0.Gemfile.
bundle install successfully installed pry on my local machine.
Please correct me if I'm wrong.
