Printing is printing. Time is _not_ time. The problem is that the
times are off by milliseconds that aren't accounted for in time.to_s.
The usual solution is to either stub Time.now or introduce a time
generator, but you're not using Time.now, so that won't work. Options
include:
1. examine the submitted argument directly
@orders.should_receive(:updated_on) do |actual|
expected = 1.week.ago.to_i
actual.to_i.should be_between(expected - 1000, expected)
end
That will expect the time within 1 second of 1.week.ago.
2. introduce a custom argument matcher
class Roughly
def initialize(expected)
@expected = expected.to_i
end
def ==(actual)
actual.to_i.between?(@expected - 1000, @expected)
end
end
def roughly(expected)
Roughly.new(expected)
end
@orders.should_receive(:updated_on).with(roughly(1.week.ago))
And for extra credit, you can even make this one more flexible and
provide a lower and upper bound using a fluent interface:
@orders.should_receive(:updated_on).with(within(1.second).of(1.week.ago))
