Hi,

Just introduced few more chapters in my Ruby on Rails 2.1 tutorial. Most  
interesting one is Unit Testing of RoR Applications.

Just go through it and send me your comments.

Tx! Now your verbiage has repeated a common misunderstanding.

test case: one ‘def test\_\*’ method that runs one event of testage  
test suite: a list of test cases with common setup & fixtures

the misunderstanding arises when a test suite inherits TestCase. This  
just means  
it follows the Interpreter Design - Suite 1–\>\* Suite 1–\>\* Case. The  
test  
runner instantiates the whole suite once for each time it runs one case.  
That  
helps Test Isolation…

Now test…

- some Views!
- some controllers from a misnamed suite. You need:

class WhateverTest \< ActiveController::TestCase  
tests MyController  
…
