Capybara vs Nightwatchjs: What are the differences?
Capybara: Acceptance test framework for web applications. Capybara helps you test web applications by simulating how a real user would interact with your app. It is agnostic about the driver running your tests and comes with Rack::Test and Selenium support built in.
