Selenium is dead, long live Selenium!! The past and future
of client side testing sso@saucelabs - @santiycr - Sauce Labs
Who’s that guy Santiago Suarez Ordoñez - Selenium Contributor since
2007 - Backend Developer at Sauce Labs - Talks, conferences, groups - Python first, JS second - Growing a moustache for men’s health
What about Sauce Labs? Browsers in the cloud Test mobile
and web apps in parallel +230 OS/Browser platforms Videos, screenshots, logs, badges, FLOSS
Evolution of (JS) testing And where it’s going
In the beginning... Client side testing wasn’t a thing
Agile and JS picked up
The first Selenium 100% Javascript Deployed with the website Firing
JS events
4 years later... Language bindings Run remotely 50% Java Code
Proxy Injection Hacks Terrible API
Great news!!
Selenium 2 (webdriver) Well designed API W3C Spec Shrinking codebase
Bad news
Still, testing is hard Test Experts Budgets Time Steep learning
curve Edgy scenarios Slow tests Flakey results
Unit tests are cheap Focused, simple, fast
Hm... need a browser Selenium!!
Selenium as a unit test vehicle
Run early, run often Continuous Integration Pre-commit On save!
Mock all the things! Reliability > Coverage
Keep them green Flakey tests == No tests
Make writing tests easy If it takes > 30’, I’m
not gonna do it
Parallelize across browsers Talk about seconds, not minutes
Tools to look at Mocha Grunt Karma Yeti Intern Sauce’s
JS Unit Testing API
Master the art of testing and testing will be your
weapon sso@saucelabs - @santiycr - Sauce Labs
