Hi all,
I am a newbie in rails. I have done some small applications in
rails but can''t know how to make TDD and BDD in RSpec and other
tools. I have tried by reading the rpesc tutorial from rspec.info
website, But can''t understand where to start coding and run for Red,
Green behaviour of code. Please help,
Thanks
deb

Please help,The theory is quite simple: instead of writing some code and then a test to exercise, write a test first (that sets out what you are trying to achieve) and then write the code for it. That flip in mindset is somewhat independent to the actual tool use use to write your tests (although some encourage it more than others) Fred> > Thanks > deb-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Buy "The RSpec Book" from Pragmatic. It''s outstanding, and will give you extremely useful insight on TDD and BDD. Cheers!! debadatta wrote:> Hi all, > I am a newbie in rails.

There is no code to implement RSpecGreeter class. You now have a successful failure. Failure is what you expected at this point. You are now at "Red." You''re next goal is to get to "Green." You do that by implementing just enough code to make the above spec pass. This involves creating the RSpecGreeter class and implementing a "greet" method that returns the string "Hello RSpec!" This is exactly what the spec says to implement. Nothing more, nothing less. Now run the spec again, which should now pass. You are at "Green." Next step is "Refactor." This is your opportunity to review the code you wrote and clean it up by removing duplication, improving formatting, etc. You can now do that refactoring with confidence because you have the spec that will tell you if you''ve broken anything, according to the specified requirement. The next step in the process is to get back to "Red" by writing another spec (or test). This is a basic BDD cycle. Keep repeating this cycle until you can''t think of any more specs to write. At that point you should have something to release (or at least be able to complete a feature story). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
