DSL methods not available when using Capybara and RSpec

[suan]

Not sure if this is expected to work? But Capybara::Screenshot::Diff is defined for me, but the DSL methods such as screenshot are not. I am currently working in a fork to determine what exactly is wrong - I suspect they may need to be added to Capybara::DSL?

Hi @suan !

Congratulations on filing Issue #1 !

When you include the gem in your Gemfile, Bundler will initiate it and the gem hooks itself into ActionDispatch::IntegrationTest, making the methods available.

Are you using ActionDispatch::IntegrationTest for your tests?

I think I found the (should've been quite obvious) issue - I use RSpec, and this gem is minitest-only :)

😄 Yes, it is, but only because that is what I am using. Would you like to help make it available for RSpec? Should not be too much work.

Solution for rspec is to add include Capybara::Screenshot::Diff::TestMethods: (Worth to mention it in docs)

require 'rails_helper'
require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist

describe 'Permissions admin', :type => :feature, :js => true do

  include Capybara::Screenshot::Diff::TestMethods

  it 'works with permissions' do
    visit('/')
    screenshot 'home_page'
  end

end

Hi!

I updated the README:

https://github.com/donv/capybara-screenshot-diff#rspec

Could you take a look and see if it explains your problem.

Hi, @donv ! Yep, that makes usage clear 👍
