Testing Framework Evolution

Explain here how testing in ruby went from regular Test:unit testing to BDD testing.

TDD vs BDD

Give high level example how they differ from each other.

Ruby Testing Frameworks

Compared to five years ago the number of testing framework available for ruby has increased rapidly. Selecting a perfect testing framework for a particular project has become harder.

Overview of testing framework

Selection of testing framework for ruby projects depends on factors like what are we trying to accomplish TDD or BDD, is GUI testing included, is acceptance testing required, do we have to merge legacy ruby test code with new testing framework. Altough GUI testing and acceptance testing are out of scope for this wiki we have made attempt to cover them in some details at the end of this wiki page. Meanwhile, below is the detailed explanation of five most commonly used unit testing framework.

Test:Unit

This testing framework is a base testing framework that is integrated inside ruby. The packages for this testing framework can be downloaded as a gem. The first version gem for this testing framework was released on 20th march 2008.

Note

There are many testing frameworks for Rails, but for this topic, I would like you to concentrate on testing frameworks for Ruby itself. Look up information on these frameworks, and describe their evolution.
