Hi Xavier
Thanks for your reply.
I want assert whether `calculate` has been called no. of times that
loop has been iterated with the same parameters every time.
And on class `InterestAmount` initializer I set the parameters in
instance variables like as follows so that I can use same instance
variables across all methods in `InterestAmount` class.
class InterestAmount
def initialize(installment, date, project)
@installment = installment
@project = project
@date = date
end
end
If you do:
class InterestAmount
def self.calculate(*args); new(*args).calculate; end
#...
end
you hide the initializer, and subsequently your tests get much nicer.
(i.e. listening to the test leads to a nicer interface)

What are you trying to test/assert here?
At a first glance, I'd refactor InterestAmount to provide an
interface
`InterestAmount.calculate`, then you don't need to use stub_chain,
and
also hide your implementation.
