I want to test a class method that sets some state and then yields a
block. It looks something like that:
class Cat
class << self
def start
id = get_uuid
begin
yield if block_given?
ensure
set_some_other_state
end
end
end
#...
end
How can I test that id field was set? Or that set_some_other_state
method was called, if I intend to use this class like this:
Cat.start do
# do what cat's do
end
I'm trying to do this like this:
Cat.start { #some block }
Cat.id.should be_something
but this doesn't work.
I also used:
Cat.should_receive(:id=).once
Cat.start {#some block}
but this doesn't let me see to what the id field was set.
Is there a better way to test this method?
Thanks,
