I'm working on a rails application on which the models are plain ruby classes without any persistence layer (no active record or similar). I want to test these models from RSpec with all the niceties that some factories provide (machinist, factory-girl). These models may get associations with persistent models in the future or may implement a custom persistance model.
Any suggestions?
I like to use the Sham gem. As long as you have a non-persistent model that conforms to some basic implementation details you should be fine. For instance, in my Rails app I would do the following:
# sham/dog_sham.rb
class Dog::Sham
def self.options
{ name: "Barney" }
end
end
# app/models/dog.rb
class Dog < Struct.new(:name)
def self.create options
self.new(options[:name])
end
end
Then in the console I can create a factory Dog using the sham command:
Sham::Config.activate!
Dog.sham!
=> #<struct Dog name="Barney">
