This document introduces Selenium, an open source tool for browser-based testing. It discusses how Selenium can be used to automatically test web applications across different browsers and platforms. It also provides examples of using Selenium to write tests in Java and integrating Selenium with other testing frameworks and backends. The document recommends starting with simple tests and keeping markup clean for better testability.

1. Selenium
Browser-Based-Testing for everyone

2. The Part for the
Consultants

3. Who, Why?
•All the cool kids (Google,
local.ch, etc.)
•Automatically test what the
user ends up with

4. Three States
of a System

6. The Bad
The Unknown
The Good

7. Goal

8. Goal
Transform requirements to
simple tests

9. Goal
Collect Tests that
correspond with your use
cases

10. Goal
Run these tests over and
over

11. Selenium IDE

15. Demo

16. Next Steps
•Download Selenium IDE
•http://seleniumhq.org/
download/
•Test

17. The Part for the
Nerds

18. Overview
•Local Tests using IDE
•Local Tests using RC
•Test on Server using RC

19. Server
Windows
Solaris
OS X
Linux
Firefox 2 / 3
Opera 8 / 9
IE 7 / 8
Safari 2 / 3

20. Server
java -jar selenium-
server.jar

21. Client Libs
•C#, Java, Perl, PHP,
Python, Ruby
browser = new DefaultSelenium(...)
browser.open(‘http://localhost’)

22. Testing
Frameworks
NUnit
JUnit
unittest
Test::Unit
TestNG
RSpec
the framework you wrote
by yourself cause you were bored
the other day

23. Example (Java)
public class GoogleTest extends TestCase {
private Selenium browser;
public void setUp() {
browser = new DefaultSelenium(quot;localhostquot;,
4444, quot;*firefoxquot;, quot;http://www.google.comquot;);
browser.start();
}
public void testGoogle() {
browser.open(quot;http://www.google.com/webhp?hl=enquot;);
browser.type(quot;qquot;, quot;hello worldquot;);
browser.click(quot;btnGquot;);
browser.waitForPageToLoad(quot;5000quot;);
assertEquals(quot;hello world - Google Searchquot;, browser.getTitle());
}
public void tearDown() {
browser.stop();
}
}

24. Don’t use the
default Xpaths.
Seriously

25. •Proper, meaningful div
classes
•correct IDs
•//body/div[2]/div/div[1]...

26. Integrate JS Tests
•JS Framework (YUI, etc...)
•Dedicated JS Testsite
•Selenium checks Testsite
browser.verifyTextPresent(‘Failed: 0’)

27. Integrate Backend
Verifications
•Your language
•Your testing Framework

28. Integrate Backend
Verifications
•Your language
•Your testing Framework
Why wouldn’t you mix in
some other tests?

29. Integrate Backend
Verifications
browser.loginUser(‘mike’)
backend.isUserAuthenticated(‘mike’)

30. Browser-Based
Tests are slow
•Yes they are
•Selenium Grid to the
rescue

31. It’s all messed up,
popups, crazy JS
and whatnot.
There’s no way I
can test that

32. Start with simple
things
browser.open(...)
browser.isTextPresent(...)
browser.click(...)

33. Conclusions
•Clean stuff is testable
(sounds familiar...)

34. Conclusions
•Proper markup is
something not only your
tests will benefit from
•RESTful is pretty
