I get where you’re coming from — a lot of LLM-based UI testing tools today do feel flaky or unpredictable. But Playwright MCP works quite differently from what you’re describing. It doesn’t rely on AI guessing or using fragile selectors.

When the page loads, Playwright MCP dynamically assigns a ref_id to every element in the DOM, and the AI simply uses those IDs to interact with the UI. This makes execution extremely stable and repeatable — no need to ‘prompt engineer’ your way past random click errors.

In fact, with a properly set up environment, test steps written in natural language can be executed directly and reliably without writing or debugging traditional code.
