Learn unit test from zero in Ruby [closed]

Question

Are there books or articles that teach to write unit test in ruby ?

Answer 1

The Rails guide to testing is pretty good: http://guides.rubyonrails.org/testing.html

Answer 2

Assuming that you want write tests using 'test/unit' the WikiBooks has article about it http://en.wikibooks.org/wiki/Ruby_Programming/Unit_testing. But there are more testing frameworks for Ruby like RSpec, then look at http://rspec.info/.
