On step 5, I'm getting this error:

[root@remandev migrate]# rake db:migrate
(in /usr/local/apache2/htdocs/testrails)
rake aborted!
uninitialized constant CreateWords

(See full trace by running task with --trace)

Just to verify, I'm supposed to replace the entire contents of the file db/migrate/001_create_words.rb with what is in the text field?

Hello, Andrzej!
I find your post, as well as your blog, very interesting.
I'm starting to write a blog about rails and TDD as well.
I think your article it would be a great start for me.
My blog is at http://www.vip2web.com and is written in portuguese, so i'm here to ask you if i could translate this post and put into my blog?

Thanks in advance!

Best regards,

Vitor

Great tutorial. This is sound advice for starting some good habits with rails. You're right about so many blogs emphasizing the quickness of rails and neglecting the testing.

Anonymous,

I see your point here.

First, this article doesn't cover all aspects of testing an application. Normally, I would start with an acceptance test (acceptance meaning something like a Selenium test). The acceptance test would describe how the user interacts with the system. This is a good place to test (indirectly) that we use something that stores data (like a relational database).

The second part of creating the Words application covers the Word.add_content method which is more related to databases.

As for the code generation, except for the application skeleton (rake file, logs directories) I don't really generate code here. All the script/generator calls generate only stubs for classes (class and method declaration).

Does it answer your questions?

Aaron,

Cool t-shirts!
It took ma a while to explain my friend (a non-IT person) why a piece of code can be "guilty" :-)

2007-05-24T09:18:00.000+02:00

Can you elaborate on how using a code generator fits with the TDD approach of "write the test, let it fail, then write the code to make the test pass", and having that drive the API design and the choice of what application behavior is implemented?

For example, why is the application even trying to connect to a database? What test code has driven the need to add DB code?

2007-05-23T22:25:00.000+02:00

I like your post. Testing seems to be easiest when you start with it from day one of an application. I like how your tests drive your development. (Your first step was to call rake test - which told you your database wasn't configured.)

Posts like these will only help increase the practice of writing good tests. Thats great because we all have a vested interests in good tests - you never know when you'll be called upon to work on an application someone else has built.

I carpool with a good friend and we 've made some tshirts that promote good programming practices like testing. Check out this shirt design and let us know what you think.

Happy testing - and thanks for the article.

Thanks for your tutorial! I live very much TDD!

2007-05-21T16:32:00.000+02:00

Looks shiny, but your example uses assert_tag, whereas nowadays assert_select is typically a much better option (and I believe assert_tag is deprecated).

In this case, I believe the code would be:

assert_select 'div', /czesc/
assert_select 'div', /hello/

But I may be misunderstanding what the assert_tag code is doing (this code checks for a div with content that matches /czesc/, and a div with content that matches /hello/).

Mr Interested,

Thanks for a positive comment! I'm going to blog more about testing.
