def class_exists?(class_name)
  klass = Module.const_get(class_name.to_s)
  klass.is_a?(Class)
rescue NameError
  return false
end

#load_spec_supports ⇒ Object

You can call this in your spec/rails_helper.rb file so you can make use of the spec supports to test concerns.

You cannot call it in the engine itself, because RSpec won’t have the same context available when tests are ran.
