CatTree

CatTree monitors ActiveRecord objects in development environment the number of objects and the number of same objects. It helps you decrease waste of memory and increase application performance.

You can be used by simply installing. CatTree notifies the result analyzing ActiveRecord objects. Look at the Rails log when Rails action finished.

Started GET "/top" for xxx.xxx.xxx.xxx at yyyy
Processing by TopController#index as HTML
  Parameters: {}
  ....

[CatTree]
  ActiveRecord::Base:     102
  Same objects:
    User(id:12):  2

Completed 200 OK in 1121.8ms (Views: 899.0ms | ActiveRecord: 222.8ms)

If you need backtrace of same objects,

CatTree::Config.backtrace = true

then

I'm glad that you would do test! To run the test suite, you need mysql installed. How to setup your test environment.

bundle install --path bundle
GEM_HOME=bundle/ruby/(your ruby version) gem install bundler --pre
bundle exec appraisal install

This command run the spec suite for all rails versions supported.

bundle exec appraisal rake spec
