Cucumber

• Cucumber is one of the implementation of Behavior Driven Development.

• It is a tool that executes plain-text functional descriptions as automated tests.

• It is Ruby based.

• In it user describe the behavior of the system with natural language with some specific keywords (Given/And/when/Then).

• The process start with creating feature files (easy update-able plain-text files explain a feature of the system and some scenario of different test situations).

• Cucumber doesn't know how to interpret the features by itself.

• To interpret the features creation of step definition is required which are written in Ruby.

• Cucumber can also be combined with a web automation framework like WATIR.
