Introducing Cucumber

Cucumber is a tool used to convert BDD behavior definitions into executable steps in several programming languages besides Ruby. Similar to the tools mentioned in the previous section, it parses the Given, When, Then format of feature specification and matches it with the proper code implementation. Cucumber has many great features that we will now explore. To save time, the majority of the existing test suites have been converted to Cucumber already; please download the new workspace from http://awful-valentine.com/code/chapter-6/part-1.
