What is Acceptance Test Driven Development in agile?

Definition. Analogous to test-driven development, Acceptance Test Driven Development (ATDD) involves team members with different perspectives (customer, development, testing) collaborating to write acceptance tests in advance of implementing the corresponding functionality.

What is difference between TDD and ATDD?

So, TDD and ATDD are levels of testing. TDD focuses on lower levels – unit and perhaps integration tests. ATDD focuses on system tests. Either of these can be combined with BDD to express tests to be more widely accessible to the variety of stakeholders involved in system development.
