# Test Quality Definition of Done - No hard waits (`waitForTimeout`, `cy.wait(ms)`); rely on deterministic waits or event hooks. - Each spec <300 lines and executes in ≤1.5 minutes. - Tests are isolated, parallel-safe, and self-cleaning (seed via API/tasks, teardown after run). - Assertions stay visible in test bodies; avoid conditional logic controlling test flow. - Suites must pass locally and in CI with the same commands. - Promote new tests only after they have failed for the intended reason at least once. _Source: Murat quality checklist._
