Capybara is an extremely useful library written in Ruby language that helps you easily simulate real users interaction with browsers. This is the most popular addition to Selenium webdriver for web automation. Its very easy to set up and use and has a number of handy methods that Selenium does not.Its popularity means several secondary benefits that are also very nice to have: since it's literally everywhere there is a lot of technical documentation, including the official Git Capybara page so you can easily set it up and start using it. Plus, since there are so many people out there using it, you can find a solution for any of your problems and questions in a matter of minutes, which is great for beginners and if that is not enough they have a group in which you can ask your specific questions.
It can simulate basic operations like clicks, opening pages, navigating them, filling forms etc. as well as more complex ones. For example, Capybara can search pages for specific elements and it also allows you to pass additional filtering blocks if you want to add non-default properties and attributes to your search. One of the other great features is that it allows you to scope the page. This means that you can restrict access to certain area on the page which also restricts certain actions such as clicking buttons or filling forms.
main capybara benefits:
• No setup necessary for Rails and Rack application. Works out of the box.• Intuitive API which mimics the language an actual user would use.• Switch the backend your tests run against from fast headless mode to an actual browser with no changes to your tests.• Powerful synchronization features mean you never have to manually wait for asynchronous processes to complete.
