The primary methodologies adopted by BDD are listed below −

Specification By Example

It utilizes examples in interactions to describe the software characteristics and its business scenarios. This methodology helps to remove any knowledge gap on the business requirements among the developers, testers, product owners, business analysts and all other stakeholders in the team.

Test Driven Development

In the reference to BDD, Test Driven Development converts examples to plain text and executable specifications. The developers refer to this as a document while implementing the new features. It helps to develop a proper code base along with a regression suite. Thus, the overall maintenance cost lowers throughout the complete product lifecycle.

BDD Tool

SpecFlow is one of the BDD tools that is open source. It contains a Feature file which follows the Gherkin syntax. The source code of SpecFlow is hosted on GitHub. It is mostly used to build automation tests for projects built in .NET. It is similar to Cucumber in its functionalities.
