What is YAML-based testing?

It's declarative E2E tests in YAML files describing user intents, with an engine (like Shiplight ) using AI to resolve and cache locators—making tests resilient to UI changes.

How does Shiplight's YAML testing differ from Playwright?

Playwright uses code with fixed selectors; Shiplight YAML uses human descriptions ("login button"), auto-healing via AI if DOM shifts, for easier maintenance and readability.

Will YAML-based testing replace my current E2E tools?

Not fully—pair it with tools like Playwright for complex cases. It's killer for standard flows, slashing maintenance by 70-80%.
