In Agile methodology, who typically collaborates to define acceptance tests?

In Agile methodology, defining acceptance tests is a collaborative effort primarily involving stakeholders and development teams. This collaboration is crucial because acceptance tests are designed to verify whether a feature meets business requirements and aligns with user expectations.

Stakeholders, which can include product owners, customers, and end-users, provide valuable insights into their needs and expectations regarding the product. Their involvement ensures that the acceptance criteria reflect actual user requirements and real-world scenarios. By working closely with the development team, who are responsible for implementing the features, the stakeholders can help clarify expectations and ensure that the acceptance tests are realistic and achievable.

The development team contributes their technical knowledge and understanding of what is feasible within the project constraints. This partnership allows for the creation of acceptance tests that are both thorough and practical, ensuring that the final product not only meets specifications but is also usable and valuable to end-users.

Thus, the correct answer emphasizes the importance of collaboration between those who have a stake in the product's success and those who are building it, resulting in well-defined acceptance tests that guide quality and usability assessments.
