Model specs live in
spec/models or any example group with
:type => :model.
A model spec is a thin wrapper for an ActiveSupport::TestCase, and includes all of the behavior and assertions that it provides, in addition to RSpec's own behavior and expectations.
require "spec_helper" describe Post do context "with 2 or more comments" do it "orders them in reverse chronologically" do post = Post.create! comment1 = post.comments.create!(:body => "first comment") comment2 = post.comments.create!(:body => "second comment") expect(post.reload.comments).to eq([comment2, comment1]) end end end
