What is Capybara, Poltergeist and PhantomJS? #

In this part I will try to cover the following aspects:

1. Running asynchronous code in a web driver
2. Making the call synchronous
3. Wrapping it into some common solution
4. Advanced example - working with IndexedDB from Capybara

PhantomJS #

First of all, we need to know what is PhantomJS. I would say it’s a ’tool that acts like a browser but can be controlled from outside using simple command interface’. In more common words, it’s a web driver. It’s a full-featured WebKit (an engine of Chrome/Safari/few last versions of Opera and other browsers), but in console. You can use it for scripting, automating or testing.
