Model specs

Model specs are marked by type: :model or if you have set config.infer_spec_type_from_file_location! by placing them in spec/models.

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 "rails_helper"

RSpec.describe Post, type: :model 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])
