Capybara is a simple and intuitive testing framework that works out of the box. It supports common testing environments like Cucumber, RSpec, and MiniTest and simulates user interactions such as clicking links and filling out forms. Capybara can test JavaScript interactions and behaviors using tools like Selenium, Poltergeist, and Capybara-Webkit. Tests can verify page content, take screenshots, and debug Poltergeist sessions.
