FactoryGirl factory for griddler email

email.rb

FactoryGirl.define do
  factory :email, class: OpenStruct do
    # to [{ full: '[email protected]', email: '[email protected]', token: 'to_user', host: 'email.com', name: nil }]
    # from '[email protected]'
    subject 'email subject'
    body 'Hello!'
  end
end

email_spec.rb

describe EmailProcessor do

  # Version with double (mock)
  it "processes an incoming email and creates a bookmark" do
    bm_count = Bookmark.count
    email = double(:email)
    email.stub(:subject) { "history,math" }
    email.stub(:body) { "This is the body." }
    EmailProcessor.process(email)
    expect(Bookmark.count).to eq(bm_count + 1)
  end

  # Version with factory
  it "processes an incoming email and creates a bookmark" do
    bm_count = Bookmark.count
    email = create(:email)
    EmailProcessor.process(email)
    expect(Bookmark.count).to eq(bm_count + 1)
  end
end

I commented out the to and from in the factory, b/c they are not needed in this spec.

You have to give the factory a class and in this case we just used and Open Struct which a base Ruby class similar to a generic class. The email class is inside the griddler gem (engine) and we don't have access to it. So we use a generic OpenStruct.
