Behavior-driven development
In software engineering, behavior-driven development (BDD) is a software development process which combines the general techniques and principles of test-driven development with ideas from domain-driven design and object-oriented analysis and design.
Description
Behavior-driven design provides software development and management teams with shared tools and a shared process to collaborate on software development.
Although BDD is principally an idea about how software development should be managed by both business interests and technical insight, the practice of BDD does assume the use of specialized software tools to support the development process.
Although these tools are often developed specifically for use in BDD projects, they can be seen as specialized forms of the tooling that supports test-driven development. The tools serve to add automation to the ubiquitous language that is a central theme of BDD.
BDD is largely facilitated through the use of a simple domain-specific language (DSL) using natural language constructs (e.g., English-like sentences) that can express the behavior and the expected outcomes. Test scripts have long been a popular application of DSLs with varying degrees of sophistication. BDD is considered as an effective technical practice especially when the "problem space" of the business problem to solve is complex.
