Behaviour Driven Development is an agile approach to delivering software with the goal of the developers, testers and product owners or business analysts collaborate to have a shared understanding of intended behaviour through examples. These examples can then be formulated into test scenarios and automated to provide evidence that the desired behaviours are implemented and working successfully. These automated test scenarios are typically written in a human readable format known as Gherkin. The three phases of BDD are Discovery, Formulation and Automation. Note that tests written in Gherkin are not inherently BDD test cases as this requires completion the Discovery and Formulation phases.

Specification by Example is an agile approach to delivering software where the requirements are defined as executable specifications. Teams identify the scope of the work and illustrate the intended behaviour through examples. The key examples are refined into executable specifications which are then turned into automated tests. These test can then act as living documentation for the software. In order to provide human readable tests for the living documentation, tests may be written in Gherkin based frameworks or other frameworks such as Concordion or FitNesse. The methodology has significant overlap with BDD and ATDD.
