  4. 4. Agenda<br />What is Continuous Integration and why do I need it?<br />How do I set it up?<br />How do I extend it to meet my needs in the future?<br />
  5. 5. Question<br />Are you using a form of source control such as Subversion, CVS, Perforce etc?<br />
  6. 6. Human’s are not good at boring tasks<br />
  7. 7. Running tests is boring<br />So Running tests manually is boring and you forget.<br />Tests break and you don’t know which change broke what.<br />The longer it takes your to discover a test failure the longer it will take to find the root cause and fix it.<br />So if your too bored to run the tests who will?<br />An Intern? The pointy haired boss? Or… <br />
  8. 8. A Robot!<br />
  9. 9. Think friendly Robot<br />
  10. 10. Not <br />
  11. 11. Your Development Cycle: <br /><ul><li>Multiple team members check in code to your version control system
  12. 12. Have a robot integrate your team’s changes and run your tests to make sure they are compatible.
  13. 13. If they are compatible release the changes to a test org
  14. 14. If they are not compatible and tests fail alert the person who broke the tests and optionally the team. </li></li></ul><li>O.K I’m interested. <br /><ul><li>Most popular Continuous Integration server in use today is called “Jenkins”.
  15. 15. Open Source with a rich set of plugin’s available to extend it’s functionality.
  16. 16. They went with the “butler” metaphor instead of “robots” in their Logo but otherwise I recommend it</li></li></ul><li>Moving Parts <br />Source Control Repository (Subversion, CVS, perforce etc)<br /> migration tool<br />Email Notification<br />
  17. 17. Lets go Shopping<br />We need to download the following:<br />Java JDK<br />Apache Ant<br /> Migration tool (via the Setup menu)<br />Jenkins<br />
  18. 18. What’s with all this software?<br />You came to the cloud to get away from installing software. <br />The good news is your actual tests will execute in the cloud using servers for the heavy lifting.<br />No need for a beefy build server<br />Proof: Win XP VM with 1 GB RAM<br />
  19. 19. DEMO 1<br />Configuring Jenkins<br />
  20. 20. Alexis Williams<br />Senior Member of Technical Staff<br />
  21. 21. Java Script & VF<br />Who use’s Java script in their visual force pages: frameworks, home grown, or combinations?<br />Who’s ever had an error in their Java script?<br />How was it found: QA, you, or a customer?<br />
  22. 22. Java Script Testing with YUI Test<br />Handles: dependencies upon page events<br />Execution types: synchronous & asynchronous <br />Simulation of actions: mouse & keyboard<br />
  23. 23. YUI Test – Test Case & Test Method<br />
  24. 24. Enter The YUI Tests & Visual Force<br />Harness the power of YUI Test on a VF page<br />
  25. 25. Selenium to the Rescue<br />Selenium IDE – Firefox add on that allows you to easily create, run, & export test cases with test methods<br />Selenium RC Server – Server that allows you to run your Selenium tests especially once they’ve been converted to Java or another language<br />
  26. 26. Selenium IDE<br />
  27. 27. Selenium & Eclipse & Selenium RC Server<br />Copy & paste the primer code from the IDE <br />
  28. 28. The Whole Enchilada <br />
  29. 29. DEMO 2<br />Jenkins Advanced<br />YUI Tests<br />Selenium (IDE / RC)<br />Ant<br />
