•
Portable software testing framework for web
applications

•
Developed by
ThoughtWorks

in 2004

•
Open source application released under the Apache 2.0
license

•
Made up of the Selenium
WebDriver
, Remote Control,
Integrated Development Environment, and Grid
applications

Selenium

•
Selenium is a tool that allows you to launch a browser,
drive the browser (open a
url
, enter some data, click on
a link) and check the browser state (a section is visible,
specific text is present, a widget is disabled
)

•
You drive the key piece in charge of controlling the
browser (through the Selenium IDE, Remote Control, or
WebDriver
) by sending HTTP requests that follow a
specific Selenium
protocol

What is Selenium

•
Selenium IDE allows you to record and then playback
tests through Firefox (user doesn't need to know the
scripting language)

•
Can also write test cases in multiple languages
including Ruby, PHP, Java, C# and
Python

Selenium IDE

You’ll want to use Selenium
-
RC whenever your test requires logic not
supported by Selenium
-
IDE.


For example, Selenium
-
IDE does not directly support
:

•
condition
statements

•
iteration

•
logging and reporting of test results

•
error handling, particularly unexpected errors

•
database testing

•
test case grouping

•
re
-
execution of failed tests

•
test case dependency

•

capture
of test
failures

Remote Control

•
WebDriver

originally was a separate project from
Selenium.


•
WebDriver

uses a different underlying framework from
Selenium’s
javascript

Selenium
-
Core. It also provides an
alternative API with functionality not supported in
Selenium
-
RC.
WebDriver

does not depend on a
javascript

core embedded within the browser, therefore
it is able to avoid some long
-
running Selenium
limitations.

WebDriver

One should use
WebDriver

when requiring improved
support for

•
Mult
-
browser testing including improved functionality
for browsers not well
-
supported by Selenium
-
1.0.

•
Handling multiple frames, multiple browser windows,
popups, and alerts.

•
Page navigation.

•
Drag
-
and
-
drop.

•
AJAX
-
based UI
elements

When to use WebDriver

Selenium
-
Grid allows the Selenium
-
RC solution to scale for large test suites
and for test suites that must be run in multiple environments. Selenium
-
Grid
allows you to run your tests in parallel to boost performance and to allow
users to run tests in different environments
