java - Test a method without initialize the class -

i'm new unit testing, i'm wondering if there way test method without initializing class. reason i'm asking because there lot of object passing in constructor meaning lot of mocking stubbing while thorough check methodtotest seems not use object attribute. it's not code otherwise method converted static.

class exampleclass {    public exampleclass(firstclass fc, secondclass sc, thirdclass tc) {}     public void methodtotest(fourthclass foc) {} } 

you have options here:

• make method static don't need reference actual object. work if method not need state of exampleclass (i.e. needs passed in method arguments).
• extract method class (perhaps using method object pattern) that's easier test on own. refactoring called replace method method object.
