Argument matcher for asserting AR object equality.

RSpec::Mocks::ActiverecordArgumentMatchers

Provide RSpec argument matcher for asserting AR object equality.

The purpose of the gem is to reduce casual use of any_instance_of : which is often used to specify a record used at far scope from an example.

Installation

Add this line to your application's Gemfile:

gem 'rspec-mocks-activerecord_argument_matchers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec-mocks-activerecord_argument_matchers

Usage

Add include configuration at spec/spec_helper.rb

RSpec.configure do |config|
  # ... snip ..
  config.include RSpec::Mocks::ActiverecordArgumentMatchers
end

Now you can use same_record_of argument matcher in an example.

let(:resource) { MyResource.create! }

specify do
  expect(SomethingCreator).to receive(:work).with(same_record_of(resource)) { :fine }

  post :something, id: resource.id
end
