Capybaras are the largest rodents in the world. They are related to guinea pigs, but are the size of a big dog or small pig. They live in South America, and they're pretty damn cute.
Capybara is also the name of a Ruby gem written by Jonas Nicklas. It helps you write integration tests for web apps by pretending to be a user with a web browser. It takes a black box approach to testing, letting you go to URLs, click links and buttons, fill in forms, and check that the rendered page contains what you think it should have in it.
This talk is about Embracing Capybara: how to understand Capybara, train it to do new tricks, and discipline it when it misbehaves.
