Rails

Hi everyone,
I hope everyone is doing well.
I am working on a scheduling system that dealing with Time.now a
lot. It is getting tricky to write test code for the function.

suppose a function in a model:

def expired?
self.expire_time <= Time.now
end

i was wondering what is the best way to test it. Or should I say
that I should design the function in the following way (more
testable?)

def expired?(time)
     self.expire_time <= time
end

then I should use it in the following way :  object.expired?

(Time.now)
it is also easier to write test code.

Any comments and suggestions will be greatly appreciated :)

thanks
Kevin

You could use Mocha (http://mocha.rubyforge.org) to temporarily stub
the Time.now method for the duration of an individual test. Something
like this…

require ‘mocha’

def test_me
specific_time = Time.parse(‘2007-01-01 06:30:00’)
Time.stubs(:now).returns(specified_time)

Time.now # => Mon Jan 01 06:30:00 +0000 2007
end
