[LRUG] Stubbing Time.zone.now

[Will Tomlins]

Hi People,

Thanks Paul and others, timecop did indeed make the problems go away.

Here's what I've done:

When /^At "([^\"]*)" I go to (.*)$/ do |time_string, page_name|
   Timecop.travel(time_string) do
     When "I go to #{page_name}"
   end
end

So then I can call the step:

When At "10-10-2010 13:00:00" I go to the home page

And everything works perfectly.


Thanks people, I'll leave you with the obligatory (terrible) Timecop quote:

*McComb </name/nm0798779/>*: That's C-4. Not only will it turn this 
house into dust, but it will also separate every part of you from every 
other part of you.

Will
