Understanding Acceptance Test Driven Development (ATDD)
Understanding Acceptance Test Driven Development (ATDD)
Acceptance Test Driven Development (ATDD) is a collaborative approach where tests are defined before development begins. The focus is on understanding the requirements from the perspective of the business and end users. ATDD ensures that the software meets the agreed-upon criteria by the time it’s delivered.
ATDD Testing Process
The ATDD process involves three key roles:
- Business Analysts: Define the acceptance criteria based on business needs.
- Developers: Implement the features that satisfy these criteria.
- Testers: Ensure the solution behaves as expected.
Tests are written in collaboration between all stakeholders, creating shared understanding and reducing rework.
ATDD Meaning
At its core, ATDD means writing acceptance tests before coding starts. These tests serve as executable specifications that describe exactly how a feature should behave. This practice aligns the development team with the business objectives, ensuring that what gets built is precisely what’s needed.
Benefits of ATDD
- Clarity: Everyone knows what “done” looks like before development begins.
- Fewer Bugs: Testing starts from day one, leading to fewer defects later.
- Collaboration: Business, development, and QA teams work together closely, reducing miscommunication.
Conclusion
ATDD ensures that tests are developed in collaboration with business analysts, developers, and testers, guaranteeing that software is built to meet clear and agreed-upon criteria.
