Is it legal to stub the #class method of a Mock object when using RSpec in a Ruby on Rails applicati
- by MiniQuark
I would like to stub the #class method of a mock object:
describe Letter do
before(:each) do
@john = mock("John")
@john.stub!(:id).and_return(5)
@john.stub!(:class).and_return(Person) # is this ok?
@john.stub!(:name).and_return("John F.")
Person.stub!(:find).and_return(@john)
end
it.should "have a valid #to field" do
letter = Letter.create!(:to=>@john, :content => "Hello John")
letter.to_type.should == @john.class.name
letter.to_id.should == @john.id
end
[...]
end
On line 5 of this program, I stub the #class method, in order to allow things like @john.class.name. Is this the right way to go? Will there be any bad side effect?
Edit:
The Letter class looks like this:
class Letter < ActiveRecord::Base
belongs_to :to, :polymorphic => true
[...]
end
I wonder whether ActiveRecord gets the :to field's class name with to.class.name or by some other means. Maybe this is what the class_name method is ActiveRecord::Base is for?
