Given/When/Then works well for acceptance-level scenarios on user-facing features — and poorly for technical tests like API contract checks, performance benchmarks, or database validations. Successful BDD adoption depends on team discipline. Without regular collaboration between product, dev, and QA during scenario writing, BDD becomes a formatting exercise rather
