Migrating From Junit 4 to TestNG

Testing next generation sounds good , for which recently I had migrated some of my unit tests written in JUnit 4 to Test NG.

Some useful features I have used and liked:

1. Annotations
2. Dependent Method
3. Groups
4. Printable and User Friendly Reports
5. CSS Configuration for reports
6. Tests runnable for various granularities like suites , groups, class , package etc
7. Eclipse plugin available
8. Data Provider
9. Spring compatibily
10. XML configuration
    
11. Many more which can be read from the Test NG documentation
