What is Domain-Driven Testing?
Domain-Driven Testing (DDT) is an approach to software testing that emphasizes the importance of the domain model as a foundation for designing and executing tests. Rooted in Domain-Driven Design (DDD), DDT seeks to ensure that the software accurately reflects the complexities of the real-world business domain it is meant to represent.
In practice, DDT involves several key principles:
- Focus on the Domain Model: Tests are derived directly from the domain model, ensuring alignment with business logic.
- Expressive and Contextual Tests: Tests are written in a way that stakeholders can understand, making them more relatable and easier to validate.
- Collaboration between Experts: Continuous collaboration between domain experts and developers is encouraged to refine the understanding of the domain.
- Use of Ubiquitous Language: Leveraging the common language shared by technical and non-technical team members to reduce ambiguity in tests.
By focusing on the domain’s intricacies, DDT provides a framework that delivers better test coverage, more meaningful tests, and ultimately leads to higher-quality software. This approach not only aids in validating the system’s functionality but also ensures that changes in the domain are accurately reflected in the tests, facilitating easier maintenance and evolution of the software.
