Should rack-test be considered an optional dependency?

[x-yuri]

I'm running swagger-ui in a docker container by providing it a swagger.json file. Which I build with rake oapi:fetch. After switching from bundle install to bundle install --without test development I realized that grape-swagger needs rack-test, which is not in the dependencies. Do you want to add it to the dependencies? Or should I install it manually? Or I'm doing something wrong? On a side note, why does the rake task need rack-test?

yes … please add it to the runtime dependencies in gemspec, it is needed for the rake tasks
