similar to: Is test driven development for newbies?

I''ve been working through the book ''Beginning Ruby on Rails E-Commerce'' which is very heavy on Test Driven Development. As in, you have to write tests for scaffolding methods and validations and crap like that. And then they fail. And you KNOW its the test not the method. So you spend 2x the time writing a test that has to be adapted when requirements change. You

Hi, I wonder what kind of interest there is on Test Driven Development (TDD) in R. Test Driven Development consists of writing the test before the function, and iteratively build the function until it passes the test. Python and Ruby (specially Ruby) have very strong test-oriented cultures. In fact, in Ruby at least the custom is to do TDD and lately Behavior-driven development (BDD). In BDD,

While the spirit of BDD is to spec first and code second, many of us have legacy code. Worse, some of us have legacy code without very good coverage. Recognizing that *I* have such code, I created a script that grinds through your .rb files and creates placeholder specs for each public method. While it is more sensible to spec behavior of code function than of individual methods, this

OK, supposedly it has Rdoc documentation but I couldn''t find it (not helped by the fact that I''ve never used offline rdocs so I don''t really know where to look). So, does anybody know how to use ZenTest effectively with Rails? I read all I could find on the web but nothing really illuminated for me. I''m trying to get into Test Driven Development (I have already

I am new to web development, Ruby on Rails, and UML as well. I was wondering if there were any free tools available for UML design. There is a list of free tools on wikipedia under UML tools, but I don''t understand if I need a tool that supports the ruby language. If anyone uses a free UML tool for designing Ruby on Rails apps, please let me know what you use.

As I work with Rails TestUnit tests I am reconsidering how to use cucumber features. It seems to me that it might be best to have a coherent view of how to arrange my test suites before I get much further into this. Now, so far I have considered three possibilities: 1. Use features exclusively. Create a feature file for each model, one for each controller and possibly an additional one for

I can understand that it''s easier for rspec to set up a mock in advance of the controller call. But it makes it difficult to do something like: context "The HarkController, given Louie the logged-in user" do setup do post :login, :username => ''louie'', :password => ''atest'' end specify "should redirect Louie to the home

Hello all, I''m new to rSpec but after reading a couple of tutorials I''ve become enamored. Anyway, I am at minute 42 of the rSpec basics screencast ( peepcode.com) and I''m having the following error running autotest w/rSpec: D:\ruby\projects\forecaster>autotest loading autotest/rails_rspec c:\ruby\bin\ruby -rrubygems -e "require ''redgreen''"

Test First Development is great...But should you use it when you are adding classes/methods on to external library that doesn''t have an extensive test suite? I noticed that the rspec plugin for autotest has no specs. David Chemlinsky said something to the list a while back that has been stewing in my subconscious - that you develop software differently using Test First

Hello, I''m scheduled to give a rspec brown bag this Wednesday (11/22) for my company (Pivotal Computer Systems, http://www.pivotalsf.com). I did see Dave Astel''s talk as well as several of my coworkers. The developers at my workplace are experienced Agile developers. What would be some good things to focus on for this brown bag? Are there slides to presentations that would be

I''ve notice that a project like Rubinius has both a spec & a test directory. Rspec has only a spec directory. Obviously I support BDD, but isn''t there also a place for state based/verification testing? I sometimes sense that I *do* want to practice Test Driven Development. That is, I want some assurance that my production code will run as intended. But I also

It seems to me that the RSpec bundle''s ''it'' snippet is in need of some love. By default, a newly inserted spec passes. This seems odd as it is misleading. It also makes it harder find what specs still need to be completed if you return to an RSpec module after a break. I propose that the ''it'' snippet is changed to the following: it

Disclaimer: The following are observations by a relatively new user (couple of weeks) of RSpec and not intended as RSpec trollbait. Also, forgive me if similar topics have been discussed elsewhere on the mailing list. I at least did the due diligence of a quick search. That said... I''ve been positively thrilled with RSpec for use outside of Rails. It has been in my attempts

Hi I hope this is not OT. I''m training my replacement at work to do BDD Rails development. He''s done a CS/maths degree but has no professional programming experience, so he''s never NOT done a project without BDD. In a way I am jealous of his unspoilt situation :) I''ve gone about things this way: * first teach him some Ruby (he did mainly Java at

Suppose we have a method ''foo'' which internally uses another method ''bar''. Being good BDDers we mock out the ''bar'' method. After all, we only want to spec the ''foo'' method - actually running the ''bar'' method means slower, less maintainable and brittler specs. That''s why we <3 mocking,

I like Shoulda. Sometimes I like plain old Test::Unit. Cucumber gives me a different thought process. I''d just like to hear some thoughts on why RSpec? What does it buy me that I can''t get with Shoulda? I just can''t seem to think in RSpec. Where is there a good example of RSpec tests that will help me grasp the right path? Thanks! -- Amos King

hypothetical question for all you BDD experts: I want to make sure that a :list action always returns widgets in alphabetical order. There''s at least 2 ways of doing this: it "should fetch items in alphabetical order" do Widget.should_receive(:find).with(:order => "name ASC") get :list end it "should fetch items in alphabetical order" do [:red,

I''m learning to use rspec and I want to see some good examples. Any recommendations of open source projects that demonstrate the use of rspec? So far I''ve found: 1) the Caboose sample app (http://sample.caboo.se/) 2) the Altered Beast forums app (http://beast.caboo.se/forums/1/topics/4650 ) Any others come to mind? I''m especially interested in seeing

Just wanted to pick some smart people about this topic: What are you guys doing to increase the speed of your specs? I''m a big fan of autotest, but right now my current project has 438 specs (for rails). Most of them are in the model, and for all of them we are hitting the database (they are more functional specs than unit-tests). The whole suite takes 112 seconds (meaning the

Hi all, I''ve been thinking about the whole validator/relationship speccing issue, and I came up with a suggestion, which I''d love to get some feedback on. The full article is available at http://www.inter-sections.net/ 2007/10/19/what-to-test-and-specify-and-where-to-do-it/ , with the relevant bit being about halfway down, but here''s the gist of it: 1.
