similar to: Stubbing Enumerable#each

I''ve just found myself stuck trying to rspec something so am hoping someone more knowledgable can help. I have a Connector class which has a class method ''results'' that yields results it get from a network service based on a set of attributes that I pass to it. I am wanting to yield these results from my Intermediate class up to the next

Hi, imagine there''s a class called Egg which has the following method (which calls another method): <CODE> def do_thing has_iterated = false self.each_row do |row| has_iterated = true unless has_iterated end has_iterated end </CODE> Stupid code, I know. I have two questions with it. The first is, would it be possible to set it up to test the case when each_row

I have the following code, which yields instance eval''s the block given: class Foo def bar(&blk) instance_eval &blk end def baz yield end end The effect of this is that self is reassigned: Foo.new.bar do # here, self is the instance of Foo # created by new end But normally self is the object in which Foo.new.bar {...} occurs. Foo.new.baz do

Ok, I followed the advice of the list and moved more code into my model from my controller. When developing tests for this new code, I ran into a problem... My model code creates a receipt object and sets some values on it: @receipt = Receipt.new do |r| r.x = 1 r.y = 2 # etc end I wanted to be able to stub out Receipt.new so that I could set expectations on the methods called on the

Hey guys and gals, I have a snippet of code: Net::SMTP(@host, @port, @from_domain) do |smtp| @emails.each do |email| begin smtp.send_message email.encoded, email.from, email.destinations @emails_sent += 1 rescue Exception => e # blah end end end What I want to do is: Say there are 4 emails. First email is sent OK On the second email smtp raises a IOError

Not sure if this is possible currently. I have a section of code like this: ActiveRecord::Base.transaction do cow.save! duck.save! dog.save! end (Names changed to protect the innocent.) I''d like to specify that the saves run in a transaction. I can do ActiveRecord::Base.should_receive(:transaction).and_yield But is there any way to specify that the code is

Hi again, my last example wasn''t good either. It really makes only sense in the context of using Thread. I finally came up with this code, that should now test all important aspects of running a task in a background thread (to keep it simple, I left out the exception handling). see http://pastie.caboo.se/35559 or end of mail. It seems, TaskRunner is now very well covered by the

Hello, I''m back again with more questions about mocks and how to do good testing in general. Let''s say I''m writing this EmailSender class and I want to make it totally awesomely tested with RSpec. Here''s how far I''ve gotten so far: require ''net/smtp'' class EmailSender def send_email

Hello Rspecers, I have a rails project where I am calling Resolv::DNS.open and then using the block to check a domain name. The code snippet in question is: domain = "mytest.com" Resolv::DNS.open do |dns| @mx = dns.getresources(domain, Resolv::DNS::Resource::IN::MX) end I obviously want to stub this out, especially for speed but can''t quite work out how. I

I have something like the following: def my_fun my_fun2 do raise Error end end I know that I can verify that the method receives my_fun2. How can I mock/stub out the example to verify that it calls raise Error? Scott

Hi All I''m working on converting some existing controller specs to use mocks and stubs rather than real ActiveRecord objects in a Rails project. In one of my controller actions, I use a database transaction. So, the obvious thing to do is have this in my setup block: Project.stub!(:transaction) Firstly, is there an easy way to have that stub yield to the block passed to any

Hi, I wanted to use wxSugar enumerable features to add a method for returning checked items'' index to the CheckListBox class : require ''wx_sugar/version'' require ''wx_sugar/wx_classes/control_with_items'' require ''wx_sugar/wx_classes/listctrl'' class Wx::CheckListBox def checked_items # use of find_all method from Enumerable

Hi, Can anyone please point me to some docs on Enumerable. I can''t seem to find anything on how to use it. Thanx -------------- next part -------------- An HTML attachment was scrubbed... URL: http://wrath.rubyonrails.org/pipermail/rails/attachments/20060327/0825d5e8/attachment-0001.html

Does anyone know the difference in performance between an ActiveRecord::find and Enumerable::find (or detect since ActiveRecord redefines the find method) for a has_many association? Here is an example: I have a list that has 10 lines and I want to find the first blank line. Which approach would be better? list.lines.detect { |line| line.content == nil } or

Hey guys, I recently published an article documenting some of the more useful and interesting parts of Prototype''s Enumerable, Hash and Array objects. You can find it here: http://encytemedia.com/blog/articles/ 2005/12/07/prototype-meets-ruby-a-look-at-enumerable-array-and-hash If you have any feedback or suggestions, fire away.

I need to simulate an enumerable class (well, it has one method: each). The code looks something like this OTTOMH: class Processor def initialize(input, output) @input = input; @output = output end def run @input.each do |row| @output << ProcessorEngine.new(row).process end end end This is the best I could come up with: @input

Folks, I''m going slightly crazy here - I implemented a Sweeper in an older app and used nearly the same exact code in my new app, yet I keep getting this ''value must be enumerable'' exception. Even after I cut most of the code away, I still get the error. If anyone can help, I would be much obliged. Notes: I''m using Engines... wonder if that could cause a

Hi all, I realize this behavior is by design, and in some respects the right thing to do. It also pre-dates the addition of Enumerable#count. I''m wondering, however, if it''s possible/desirable to allow the caller to access the Enumerable versions under certain conditions. I originally wrote the up as an issue, but was informed this would be the better venue. I''m

I''m having trouble figuring out how to drive the design of a class. I''m hoping I can get a hint or two from the more experienced BDDers on this list. I''m writing an adapter class that sits between a 3rd party library and my business logic. I would like to extract some information from objects available from the 3rd party lib and covert them into ruby objects.

This might seem like a really daft question, but I couldn''t find an answer anywhere. How do you add something to an enumerable object? Something like var first = $A(getElementsByTagName(''td'')); var second = $A(getElementsByTagName(''tr'')); first.PUSH(second); where the PUSH is something unknown. am i supposed to use inject here in some way?
