Difference between PhantomJS and Google Chrome

[RémyB]

Well I have a test suite that run perfectly with Chrome but when I run the suit with phantomJS it failed with warning exit message, the element is not displayed... and the funny thing that is work on the CI server but not on my macbook pro, I am using Selenium v2.43.1 .

also sometimes all test run successful but the build can't quit selenium instance so the build is failing :
