JUnit for Java ME
Sony Ericsson just released Mobile JUnit 1.0 for Java ME CLDC handsets.
I believe J2MEUnit is the most popular one. Now it is integrated into Netbeans Mobility Pack 5.5. One thing worries me is that J2MEUnit project source code has not been updated since 2003.
JMUnit is a new project on sourceforge.
So, now we have three options. Why don’t people just focus on one and keep improving it?

Thanks for the pointer Wendong… Agreed - focus on one and improve it…

Awesome! I am really impressed by the speed that your switch to a new unit testing library, given the fact that there are so many innovative stuff going on in Mobility Pack.
