Checking ActiveRecord Associations in RSpec

Question

I am learning how to write test cases using Rspec. I have a simple Post Comments Scaffold where a Post can have many Comments. I am testing this using Rspec. How should i go abo

Answer 1

If you'd rather not use an external gem like shoulda to test your associations (see Robert Speicher's Answer for details on that), another option is to use reflect_on_association to get the AssociationReflection object for the relevant association, and then assert on that:

describe Post do
  it "should destroy its comments when it is destroyed" do
    association = Post.reflect_on_association(:comments)

    expect(association).to_not be_nil
    expect(association.options[:dependent]).to eq :destroy
  end
end
