What is

BDD was created by Dan North as as a response to the issues encountered teaching test-driven development (TDD) and is basically a way to rethink the approach to unit testing and acceptance testing.

• How software development managed by both business interests and technical insight.

• Requirements are specified in a way that they are explicit, executable and testable.

• The BDD tools serve to add automation to the ubiquitous language which is the central theme of BDD.

Ubiquitous

Gherkin is a Business Readable, Domain Specific Language that lets you describe software's behavior without detailing how that behavior is implemented.
