SpecByExample
Specification by Example (SpecByExample) is a collaborative approach for defining software requirements and creating executable specifications based on real-world examples. In BDD, this technique is used to establish a common understanding of requirements among team members, encourage collaboration, and create a shared vocabulary. SpecByExample involves working together with stakeholders, product owners, developers, and testers to generate realistic examples that reflect how a system is expected to behave in different scenarios. These examples can be converted into a living documentation, which serves as a single source of truth for the development team, and helps to drive the development process, validate the implementation, and facilitate knowledge sharing across the team.
Guide: SpecByExample in Agile Project Management and Behavior-Driven Development
SpecByExample is a key technique used in Agile Project Management and Behavior-Driven Development.
What it is:
SpecByExample is an approach to defining software acceptance criteria and test cases on the basis of illustrative examples. It allows the project stakeholders to describe how the system should behave in response to specific inputs or scenarios.
Why it is important:
The SpecByExample approach aids in creating clear, concise, and executable specifications. It facilitates seamless communication among developers, testers, and business stakeholders – and ensures that all parties have the same understanding of requirements. Specifications by Examples also helps in building robust automated testing procedures.
How it works:
The process typically starts with a workshop where examples are discussed and agreed upon by the team and other stakeholders. These examples then form the specifications for the software. The development team work on implementing these specifications. Once a specification is met by the system it is considered 'done'.
