I have fix the issue and test it (actionButton.js) in my local server, and following Marius' advice, I have written a selenium test for it, and the test was failed when I do nothing to the source codes, which is what it should be. And I want to update the fixed codes to the source codes in github, and run the test again to see if the fix pass the test. However, I found that the actionButton.js which I have modified is located in xwiki-platform, but I run the test under xwiki-enterprise, what is the best practice to test modified codes of xwiki-platform under xwiki-enterprise. -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University
