1
Introduction

• Selenium IDE is a Firefox extension that allows
  you to record, edit, and debug tests for HTML
• Easy record and playback
• Intelligent field selection
• Autocomplete for all common commands
• Walkthrough tests
• Debug and set breakpoints

2
Known Bugs

• Doesnt save Base URL
• Fix Enter base URL as the target in the initial
  open command
• Locks up a lot. Ex.) No base URL
• Fix Close and reopen
• Doesnt wait for pages to load
• Fix Use pause command and wait for a while
  before attempting next step
• All addresses must be complete (including
  http//) otherwise it locks up

HTML

• Selenium saves all information in an HTML table
  format
• Command Tells Selenium what to do using actions
  or assertions Ex.) type
• Target Tells Selenium which HTML element a
  command refers to Ex.) textbox
• Value Used for any command that might need a
  value of some kind Ex.) Hello

Command Actions

• Open
• Opens the target URL
• Click
• Clicks on the target element
• Type
• Enters the value specified by the value into the
  specified target element
• Select
• Selects a drop-down value specified by the value
  in the specified target element

5
Command Actions

• SelectWindow
• Selects a popup window using the id specified by
  the target. If NULL, it returns to the main
  window
• GoBack
• Simulates user clicking back in the browser
• Close
• Simulates user clicking the close button of a
  popup window
• Pause
• Pauses the execution of a script for an amount of
  time in milliseconds specified in the target

6
Command Actions

• fireEvent
• Simulate an event to trigger the onevent handler
  where the target specifies the element and the
  value specifies the event
• waitForValue
• Waits for an input, specified by the target, to
  have a certain value, specified by the value
  (Warning If event doesnt occur, apply previous
  fix to stop running script)
• Store
• Stores the value specified by the target into the
  variable specified by the value

7
Command Actions

• StoreValue
• Stores the value of an input field, specified by
  the target, into a variable specified by the
  value
• storeText
• Stores the text of an element, specified by the
  target, into a variable specified by the value
• storeAttribute
• Stores the value of an element attribute into a
  variable

8
Command Actions

• chooseCancelOnNextConfirmation
• Instructs Selenium to select cancel on the next
  javascript dialog raised
• answerOnNextPrompt
• Instructs Selenium to return the specified target
  in response to the next prompt.

9
Wait

• Used when going to a new page

10
Assert Vs Verify

• Assert Big deal
• Verify if fail, continue

11
Advanced Selenium

• Selenium IDE is great for recording a few simple
  tests for small projects, but
• Widen Enterprises
• Business based entirely on a collection of
  integrated web-based applications
• Over 2.5 million lines of code
• Over 30 tailored client-specific distributions

12
Advanced Selenium

• Selenium TestRunner
• Open source framework
• Write test classes that extend SeleniumBase
• Each class is a suite
• Write setup and teardown routines
• Override a function order to tell Selenium what
  functions are tests and what order they should be
  run in
• Write test functions!

13
Advanced Selenium

• More on TestRunner
• Compile tests using Ant task
• Go to applications /selenium
  pagehttp//.../selenium
• Choose a test suite from the list

Advanced Selenium

• Advantages of TestRunner
• Can use constants for element values
• Can use supporting subroutines to simplify test
  running
• More intuitive than coding the HTML table!
• Disadvantages
• Requires some configuration of the web server
• In the end, all youre getting is the HTML table
• Still no conditionals, while loops, etc.

16
Advanced Selenium

• Driven Mode
• Uses Ruby
• Highly-dynamic, interpreted programming language
• No static HTML
• Ruby code itself drives the test
• Conditionals!
• Can use IF, WHILE, and other logic in driving
  the test
• Results
• Generates report HTML files showing the status
  of all tests that were run

17
Advanced Selenium

• Problems with Driven Mode
• Only works with FireFox
• Configuration can be difficult
• Automatic, but not quite regression
• No easy way to kick off test suites overnight

18
Conclusion

• Web-based testing is hard!
• Web-applications are still fairly new
• Structure of HTML is far more free-flowing and
  dynamic than a regular app
• Limited software available
• Selenium is
• Free
• Well-supported
• Can tailor to your needs offers versions that
  are quick and easy, highly-maintainable, or
  dynamic.
• If its good enough for a 2.5 mLOC project, its
  probably good enough for you
