Hello Sir,


A your suggestion i do agree with you create new class for very long method as u suggested.

In this case how do you write unit test?

Is it possible to create interface instead of calss ?

Please give explanation.

Hey Mahendra,


Nice question! Here's what I think:

1. You need a class anyway, since you have to put the extracted method body somewhere. You can not put it inside interface, right?

2. You can always extract interface from a resulting class later (see Extract Interface refactoring).
