require JUST ActiveModel::Validations in an rspec test

Question

I have a class that I'm trying to test that includes ActiveModel::Validations

module SomeModule
  class SomeClass
    include ActiveModel::Validations
  end
end

I'm trying to test it without spec_helper to keep it fast, but a simple require 'activemodel' at the top of the spec doesn't work. I keep getting an uninitialized constant SomeModule::SomeClass::ActiveModel(NameError). for the spec file:

require 'activemodel'

describe SomeModule::SomeClass do

end

Any tips on solving this? Thanks in advance!

You will need to include active_model in your module/class file.

# /some_class.rb

require 'active_model'

module SomeModule
  class SomeClass
    include ActiveModel::Validations
  end
end

Spec,

# /some_class_spec.rb

require './some_class'

describe SomeModule::SomeClass do

end

You'll want to change the paths to match your files. I doubt this will speed up your specs when run with other specs that include the whole Rails stack, but when run by itself this will be a little faster.
