What it does
Playwright ships three official built-in AI test agents out of the box starting in v1.56: Planner, Generator, and Healer. Planner explores the app and produces a human-readable Markdown test plan of scenarios from user flows. Generator converts that Markdown plan into executable Playwright test files, verifying selectors and assertions live as it performs each scenario. Healer replays failing steps, inspects the current UI, and suggests a patch — a locator update, wait adjustment, or data fix — re-running until the test passes or guardrails stop the loop. The agents install as editable Markdown prompts plus MCP tool definitions, with no third-party dependency.
How QA teams use it
- Run Planner against a user flow to get a reviewable Markdown test plan before any code is written.
- Feed that plan to Generator to produce verified, executable Playwright spec files.
- Point Healer at a failing CI run so it inspects the UI and proposes a locator, wait, or data fix, iterating until the suite passes.
Setup
Install with npx playwright init-agents, which sets up the agents as editable Markdown prompts and MCP tool definitions.
Notes
First-party Microsoft/Playwright tooling, requires Playwright v1.56 or later.
