    Intro Of Selenium Intro Of Selenium Presentation Transcript

    • Intro of Selenium
    • Objective
      • Introduction to aspects of Selenium
      • Target audience: anyone who has interests in web-app automation
    • Dilemmas
      • UI changes
      • Platforms
      • Browsers
      • Development efforts
      • Maintainance efforts
    • What is Selenium?
      • Web-based App testing tool, running directly in browser.
      • Implemented entirely with browser techs
        • DHTML
        • JavaScript
        • Frames
      • Works by inspecting DOM
    • What can do?
      • Browsers-compatible testing – one script, many browsers
      • Acceptance testing
      • Regression testing
    • Behind the scenes
      • Deploy BrowserBot alongside AUT
      • Use JS and IFrame to embed BrowserBot
      • Engine is tweaked to support wide range of browsers on different OS
    • Quick Demo
      • Access google.com
      • Input keyword “selenium”
      • Verify a link
    • Script looks
      • Html table
      <table cellpadding=&quot;1&quot; cellspacing=&quot;1&quot; border=&quot;1&quot;> <tr> <td> open </td><td> / </td><td></td> </tr> <tr> <td> type </td><td> q </td><td> selenium </td> </tr> <tr> <td> clickAndWait </td><td> btnG </td><td></td> </tr> <tr> <td> verifyTextPresent </td><td> selenium.openqa.org </td><td></td> </tr> </table>
    • Script model selenium.openqa.org verifyTextPresent btnG clickAndWait selenium q type / open Value Target Command
    • Action
      • open
      • type
      • click
      • select
      • clickAndWait
    • VP
      • verifyXXX
      • assertXXX
      • For ajax use:
        • waitForXXX
        • waitForCondition
    • Locators
      • Identify elements via locators:
        • id=id
        • link=name
        • dom=document.select[2]
        • xpath=//input[@name=‘btn’]
        • css=a[href=‘#id2’]
    • String matching
      • glob:pattern
        • *
        • ?
      • regexp:pattern
      • exact:string
    • Playback
      • Run
      • Walk
      • Step
    • Test Suite
      • Html table
      <table> <tr> <td>Test Suite</td> </tr> <tr> <td><a target=&quot;testFrame&quot; href=“google.html&quot;>test Google</a></td> </tr> </table>
    • Components
      • Core
      • IDE
      • RC
      • Grid
    • Selenium Core
      • Basis of Selenium IDE and RC
      • Runs test suites on the same server to avoid the Same Origin problem
      • Don’t have same flexibility as RC, but tests and code under test is in the same spot
    • Selenium IDE
      • for quick recording of tests, but it somewhat lacks for power
    • Selenium RC
      • Different langs binding
      • Gives the ability to drive Selenium from a real programming language (Java, Perl, Python, Ruby, and more)
    • Selenium Grid
      • extends Selenium RC to distribute your tests across multiple servers, saving you time by running tests in parallel.
    • Browsers support Partial N/A Others Y Y N/A Opera 8 Y Y N/A Opera 9 Y Y N/A Safari 2 Y Y N/A Safari 3 Y Y N/A IE 7 ? ? N/A IE 8b1 Y Y Y FF 2 Y Y Y FF 3 Core RC IDE Browser
    • OS Support Y Y works on FF 2+ Others Y Y works on FF 2+ Solaris Y Y works on FF 2+ Linux Y Y works on FF 2+ OS X Y Y works on FF 2+ Windows Core RC IDE OS
    • Tips
      • Data-driven
      • Dynamic pages(php, jsp)
      • Record your script in S-IDE, then use it as a base for a S-RC script
      • Use Firebug to give you the XPath
    • Extension
      • There are a lot of commands - you can even add your own custom commands into the user-extensions.js
    • Problems encountered
      • Bug
      • Tweak
      • Not support native dialog
    • Selenium vs. RFT
      • Development
      • Deployment
      • Platform/browsers support
      • Maintainance
      • Scope
      • Use right tool case by case
    • Where to get?
