Question

I have a model with polymorphic association that I am running rspecs on.
The tests require the polymorphic field to point to a model with some fields (e.g. name).

Since I prefer not to use any of my existing (and complex)models, I was thinking of somehow creating a new simple models (that will only exist in tests) that my main models can point to.

Is there a way to do this ?
Any other way to test models when they are dependant on another models ?

Problem solved – using the ‘mocha’ gem.

class Comment < ActiveRecord::Base
  belongs_to :commentable, :polymorphic => true
end

In tests, can just do:

class MockUser {
# Stuff
}

comment = Comment.create!.expects('commentable').returns(MockUser.new)

Now it will simply work:

comment.commentable.name
