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.

Our workspace project structure has changed a little bit to accommodate some of the cucumber conventions. Let's take a look how the files are now arranged:

As you can see, the test suite structure has not changed much from what it used to be in the previous chapter, except a couple of files were moved and renamed, and several were deleted. Let's take a closer look at the Cucumber-specific changes.
