Simulacrum can also be configured once included;

RSpec.configure do |config|
    include Simulacrum

    Simulacrum.configure do |simulacrum|
        simulacrum.images_path = 'somewhere/example/spec/ui_specs'
        simulacrum.acceptable_delta = 0.1 # allow a maximum of 0.1% difference
        config.defaults.capture_selector = '.kayessess__examples'
    end
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
