TestNG support

Now I use TestNG to replace JUnit for unit test, and unitTest can work very well, such as generate testcase class and method, refactor and so on. But I have a problem, navigation from test method to tested method does not work. When I invoke "Ctrl+Shift+T" on test class or test method, and unitTest give me an error dialog as following:
title: Tested class not confirm
content: Current class XXXXX.java does not confirm to the defined test organization.

Note: test method name in TestNG testcase is still with prefix of "test".
