Provides a client implementation of the W3C WebDriver specification with support for Chrome and Firefox.
In the past, I've used selenium-webdriver for testing web applications. However, I found it to be slow. I wanted to improve the performance of my tests, so I decided to write a new implementation from scratch. The W3C WebDriver specification is quite simple, so it wasn't too difficult to implement, and I was able to get a significant performance improvement, between 2x-10x depending on the usage. Specifically, most test suites can take advantage of pre-warmed sessions, which can minimise the overhead of each test running in a new session. Additionally, I'd like to explore reusing sessions between tests, which could provide even more performance improvements.
In addition, building on top of async allows us to take advantage of async-http and run the web server in the same reactor as the test itself, which can provide a performance improvement over capybara which usually needs to start a separate server process. This also makes it possible to share a single database transaction between the client and server, which can significantly reduce the overhead of "cleaning" the database after each test, and improve the opportunity for parallelisation.
