RubyConf Colombia 2017: Building the New Rails System Test Framework

by Eileen M. Uchitelle

Published September 8, 2017 in Programming

At the 2014 RailsConf DHH declared system testing would be added to Rails. Three years later, Rails 5.1 makes good on that promise by introducing a new testing framework: ActionDispatch::SystemTestCase. The feature brings system testing to Rails with zero application configuration by adding Capybara integration. After a demonstration of the new framework, we'll walk through what's uniquely involved with building OSS features & how the architecture follows the Rails Doctrine. We'll take a rare look at what it takes to build a major feature for Rails, including goals, design decisions, & roadblocks.
