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.

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

See https://github.com/stephencelis/miniskirt/issues/19.
