Hey Guys,
I am working on my first TDD/BDDD example and running into a problem,
when I run ''ruby app.rb" The app seems to run fine, but when I run
it''s rspec ''spec app_spec.rb" I get a no method defined.
app.rb
require ''rubygems''
require ''open-uri''
require ''hpricot''
class Timer
#this is the retrieve method used to retrieve the contents of the xml
file
def self.retrieve
doc = Hpricot(open(''some site''))
#get the times
times = doc/"//times"
puts times
end
end
Timer.retrieve - this works fine
rspec
require ''app''
describe Timer do
it "should retrieve the xml info from the site" do
Timer.should retrieve
end
end
error:
NameError in ''Timer should retrieve the xml info from the
site''
undefined local variable or method `retrieve'' for
#<Spec::Example::ExampleGroup::Subclass_1:0xb6dc9c70>
./app.rb:7:
Hope that''s clear enough, I am a tad confused about what''s
going on,
it looks pretty clear cut.

Try something like this: describe Timer do it "retrieves xml from the site" do Timer.retrieve.should == "whatever you''re expecting" end end> Hope that''s clear enough, I am a tad confused about what''s going on, > it looks pretty clear cut.
Thanks David, That helps a lot and makes a lot of sense. Neat article by the way, was following to get a hang on rspec. Cheers!
