I am a beginner in ruby and I have read the “Unit testing” chapter in
Programming Ruby book. I want to study Unit testing using ruby in much
more detail.
Can somebody point me towards a good resource for that ?
thanks

you might want to google for a few terms related to that like
TDD (or test driven design)
or
BDD (behavior driven design)
I’d recommend “The RSpec book” from the Pragmatic Programmers which is
currently in the last stages of their beta program, which means that
you can buy the book as a PDF and optionally get the printed book when
available.
http://pragprog.com/titles/achbd/the-rspec-book
As the name implies the book covers rspec rather than test::unit.
RSpec has become a very popular alternative to test::unit for many
Rubyists. It also covers Cucumber which is a higher level framework
for writing user-level specifications/acceptance tests. The pair work
very well in combination.
There’s also another pragmatic programmers title in beta “Rails Test
Prescriptions” by Noel Rappin.
http://pragprog.com/titles/nrtest/rails-test-prescriptions
This was a self-published book, which focused more on Test::Unit, but
included material on RSpec/Cucumber. It’s been picked up as a title
by the prags, I believe that it’s more focused on Rails than the RSpec
book, which covers the use of RSpec/Cucumber with Rails apps in the
context of doing BDD in Ruby, whereas the Rappin book looks like it
covers the use of RSpec and Cucumber as an extension of the Test::Unit
based testing framework in Rails.

An oldie but still a goodie is Kent Beck’s Test Driven Development By
Example. The examples are not in Ruby but they translate well and the
book as a whole provides a strong foundation for TDD and testing in
general.

It’s been in the last stages of beta for a really long time now 
It’s
release date has been pushed back at least three times this year
already.
There was also supposed to be a book on RSpec by Apress but it seems
nothing
ever happened with that (it is alleged to already be released
Amazon.com)
And Addison-Wesley was supposed to release a book on it back in April,
but
that hasn’t happened and the book’s page is now gone from Amazon. Back
in
Feb I was asking about these books (
Foundations of RSpec - Ruby - Ruby-Forum) Noone really had much to say.
I enjoyed your blog about creating your own RSpec book from the beta
PDF. (
http://talklikeaduck.denhaven2.com/2009/09/12/and-now-for-something-completely-different-diy-bookbinding-on-the-cheap)
And I have it since my boss pre-ordered. But I have a hard time
motivating
myself to try and read something that I feel like is going to be
deprecated
soon. I won’t have the time or motivation to read it twice.
@Lakshmana: the first chapter of Ruby Best Practices is about testing
(Test::Unit) the book is not really aimed at people new to Ruby, but it
has
a lot of code examples, and you can download the PDF for free from
http://rubybestpractices.com/ (if you’re satisfied, you can support Open
Source and the author, by purchasing it
O'Reilly Media - Technology and Business Training) Although, I just
glanced at the Pickaxe’s chapter on unit testing, and I’m not sure
whether
RBP has more to offer (still, free to check it out). Still, don’t get
hung
up on whether you understand every nut and bolt of everything. The
Pickaxe’s
chapter looks like it should be good enough to get started, and it is
more
important that you incorrectly start, than that you correctly do not
start.
Once you get started, you’ll have a better understanding of the domain,
which will make it easier to learn from reading other resources later
down
the line. In other words, you can begin testing with just a bare minimum
of
tools, and you should.
RSpec’s documentation is also pretty good
And I feel like I …oughta… mention shoulda, b/c there are a lot of
Rubyists who like it, but I honestly know next to nothing about it, so
I’ll
let someone else fill in those details. Here is their github, though (
GitHub - thoughtbot/shoulda: Makes tests easy on the fingers and the eyes).
I also feel like I should mention that there are two Peepcodes about
RSpec,
but a lot of the stuff in them is already deprecated and doesn’t work,
and
it’s especially frustrating when learning the unfamiliar, if you don’t
really know what something does, but it isn’t working, and you aren’t
sure
why not, or how big of a deal it is. NOTE: I just went to check it out,
and
they now have 4 peepcodes on BDD, including cucumber and mocking. The
ones I
watched say they have been updated, but I’m not sure if that was before
or
after I tried going through it. (http://peepcode.com/)

It suffers from the same fate as many books for Ruby, which is chasing
a moving target.
The current delay is that it was decided to delay the release until
RSpec 2 is released, which is also being coordinated on the release of
Rails 3.
Even in its current ‘beta’ form it’s quite complete and useful.
