“WHAT IS SELENIUM? TELL ME LIKE I’M 5.”

Selenium is a software robot sent from the future to test our software.

PREFACE

There are many ways to implement Selenium & a framework

I will show you one that has worked for me

There will be code involved (and opinions!)

These examples do not reflect a comprehensive QA strategy

But it’s a good start

SELENIUM IDEI debated showing you the IDE since it’s the unloved child of the Selenium community.

But it is responsible for the wide spread success of Selenium.

I consider it to be less of an unloved orphan and more of a gateway drug

SELENIUM IDIOMS

• Verify vs. Assert

• Location, location, location!

• ClickAndWait, and wait, and wait...

LET ME EXPLAIN

• Ruby is approachable -- it can read like English

• There’s also that “standing on the shoulder of giants thing”

• RSpec is an open-source testing tool built in Ruby for Ruby

• It’s kind of a big deal

• Loads of functionality out of the box

•Quite customizable

“NO REALLY, SHUT UP AND SHOW ME

THE CODE!”

PAGE OBJECT PATTERN

• Relieves many test maintenance woes

• Keeps things DRY rather than WET

• Create an object that represents a page (or component of a page) and test against that

• If the UI changes, you change just the object, not the tests

• Also helps you make things more readable

Create a classPass the session to itStore and use it through an instance variableAssertions done outside of the class
