Selenium
what it is and what you can do with it

2.
Selenium
● Web testing framework
● A faster way to see if your site works
● Real browsers for fidelity
Test
Server
Browser

3.
Applications
● Cross-browser testing
● Continuous integration
● (Scraping & automation)

4.
Ecosystem
●
●
●
●
Two versions
Many language bindings
Two development environments
Many playback backends

5.
Selenium IDE
Selenium 1 Test
Selenium Builder
Selenium 1 Code
Selenium 2 Code
Builder JSON
Selenium 1 APIs
Webdriver APIs
Se Interpreter
HTML
Ghost
Selenium Server
IE
Firefox
Chrome
Opera
Android
etc.

6.
Selenium 1 vs 2
● v 1 is a list of testing steps
● v 2 is an API for remote-controlling browsers

7.
Selenium 1 Tests
● Sequence of test steps
● “Go to this page, click on this link, does this
text appear?”
● Stored as “Selenese” table or code

8.
Selenium 2 / Webdriver APIs
● Write code to control the browser
● Python, Java, Ruby, Perl, PHP, C#, node,
Groovy, etc.

9.
Locators are for finding stuff
● Locators refer to page elements
● Multiple strategies: id, class, text, xpath…
● Ideally robust to minor page changes

10.
Playback fidelity is hard!
● Javascript is everywhere: you can’t test a
page just by looking at the HTML
● Want to run tests quickly but waits needed
● Reliable locators can be hard
● CSS rollovers, element visibility, etc.

11.
No silver bullet blah blah blah
●
●
●
●
Selenium uses real browsers for fidelity
Implicit waits sometimes work
Write clean, testable pages
80/20 automated/manual is still nice

12.
Getting started with Selenium 2
● Get language bindings
● Write your first test
● Run your first test

demo

14.
Builder+GitHub+Travis+Sauce = CI
●
●
●
●
Record tests with Selenium Builder
Store them on GitHub in the project repo
Use Travis to drive test runs on commit
Use Sauce Labs’ Selenium servers

16.
Substitutions
● Builder: IDE or hand-coded scripts
● Travis: another CI system, e.g Jenkins
● Sauce OnDemand: your own infrastructure
or another provider like TestingBot
