How to test Rails Engine models with miniskirt?

Question

I've run into a snag while trying to test a Rails 4 engine using miniskirt.

I have a model test set up in test/models/job_manager/job_test.rb:

require 'test_helper'

module JobManager
  describe Job do
    before do
      @job = Factory.build(:job)
    end

    it "is a valid object" do
      @job.valid?.must_equal true
    end
  end
end

My miniskirt factory is currently defined as:

module JobManager
  Factory.define :job do |j|
    j.title 'Job Title %d'
    j.description 'Lorem ipusum dolor sit amet consecateur ad piscin'
  end
end

And the error I get is:

uninitialized constant Job
Exception `NameError' at:

… which traces back to line 6 in the model test (@job = Factory.build(:job)). Replacing it with @job = Job.new works fine, but then I'm not using miniskirt factories any more. I get this error whether the factory is defined in the JobManager module or not.

Answer 1

As per Stephen Celis, Factory.define doesn't use the current scope to resolve constants. This solved the problem:

Factory.define :job, class: JobManager::Job do |j|
  j.title 'Job Title %d'
  j.description 'Lorem ipusum dolor sit amet consecateur ad piscin'
end
