Problems with RSpec 2.x about fakefs

[smtlaissezfaire]

You'll probably want to require 'fakefs/safe'. Fakefs takes over the full filesystem - so if rspec is trying to require something, it won't find the file ("rspec/mocks.rb") it in the fake filesystem. You might also take a look at the rspec helper in fakefs which should setup the fake filesystem for each test case (in before(:each)) and tear it down.

I'm going to close this one out. If you are still having the same problems after requiring "fakefs/safe", please reopen this ticket.

Makes sense. fakefs/safe does seem to help. You can also require the things that might be required in code you're invoking in advance (e.g. require 'rspec/mocks'), but that raised some other issues, so fakefs/safe is probably a better approach for me.
