How to add additional test methods in a testing class in eclipse - junit (Unrooted??)

Hi , i currently right click on the class and for each method of the class i am allowed to create one testing method.
Is it possible to create multiple testing methods for only one method of a class that needs to be tested??
If i add another custom method in the test generated class I get the error
Unrooted Tests..
Initialization Error
How can i make this method(test) rooted also?? Why is it being called unrooted ??

Problem solved annotation was missing
