Simulacrum

An opinionated UI component regression testing tool built to be tightly integrated with RSpec, Selenium and tools you already use.

---

Installing

gem 'simulacrum'

Configuring

RSpec.configure do |config|
  config.include Simulacrum
end

Simulacrum can also be configured once included;

Simulacrum.configure do |config|
    config.images_path = 'somewhere/example/spec/ui_specs'
    config.acceptable_delta = 2 # allow a maximum of 2% difference
end

Usage

Simulacrum provides a small DSL for configuring and managing UI tests from within Rspec. Basically it boils down to these three methods;

• component
• configure_browser
• look_the_same
