Mocking local method variables with mockito / powermock

Question

I have a method which takes in a string as a parameter.

However locally the method creates and uses a List and an instance of SingleColumnRowMapper.

Is there anyway using mockito/powermock once instances of these objects have been created/mocked in the unit test to place them as local variables into the method to be tested.

Thank You

Answer 1

SampleClass classInstance = Mockito.mock(SampleClass.class);

The above code mocks the instance creation of a class. If you want to create any instance, create it similarly and supply it to your method.
