Browser/Javascript Integration Testing with Ruby

Browser/Javascript Integration Testing with Ruby

  • Jessie Keck, Stanford University, jkeck at stanford dot edu

It's near impossible to build a rich web application without javascript. We have a lot of great patterns to follow, such as progressive enhancement, to make sure our rich web applications are usable, accessible, and testable. However; when javascript is involved the possibility exists that bugs can be introduced that won't get caught by most unit and integration testing frameworks.

This is where Watir (pronounced water) comes in. Watir can be used with popular ruby testing frameworks like RSpec and Capybara. This talk will show how to use the combination of these tools to write RSpec tests using Watir to spin up an application in a variety of browsers, navigate the application, and make assertions about the page using Capybara.

Tests using Watir are written in ruby but they don't necessarily need to test ruby application. You can test any application that you can point a browser at, so there are a wide variety of potential uses for tests written with Watir.
