java - how to unit test a class that uses a factory? -

-

if have class foo gets objects factory, how unit test foo?

class foo {   void dosth(){     anobject object = factory.instance().getobject();     object.dosth();   } }

i'm going have call factory in unit test of foo, aren't i?

is spring dependency injection give me advantage, because can do

class foo {   setfactory(factory factory){     this.factory = factory;   }   void dosth(){     anobject object = factory.getobject();     object.dosth();   } }

or there workaround in non-spring world?
