mock example

gistfile1.rb

it "should lookup by last_updated for abc files" do
  update_time = Time.now
  # create a location to match this update_time here
  file = double("file")
  file.should_receive(:extension).and_return("abc")
  file.should_receive(:last_update).and_return(update_time)
  MyClass.load_file(file).should == Location.find_by_lookup(update_time)
end

it "should lookup by extension for all other files" do
  # create a location to match the "def" extension here
  file = double("file")
  file.should_receive(:extension).twice.and_return("def")
  file.should_not_receive(:last_update)
  MyClass.load_file(file).should == Location.find_by_lookup("def")
end
