For frontend engineers authoring UI — how to make components reliably locatable by tests and AI agents. Covers the official Playwright locator priority, semantic/accessible markup first, and how to add valid, unique, stable `data-testid` attributes (naming convention, uniqueness in lists, stability rules) for React, Vue, Angular, and Svelte. Use when writing or reviewing components, or when an agent needs durable locators.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Playwright Frontend (Authoring Locatable Markup) > Audience: **frontend engineers writing the app** — the counterpart to the test-author guides in `core/`. Your job here is to expose a small, stable, machine-readable contract on the DOM so tests *and* AI agents can locate elements deterministically, without flakiness. A `data-testid` is a **public API for your UI's automation layer**: once a test or agent depends on it, renaming it is a breaking change. Build accessible markup first, then add deliberate, well-named, unique, stable test IDs where automation needs a durable handle. ## Guide Index | Topic | Guide | |---|---| | `data-testid` conventions (when, naming, uniqueness, stability) | [data-testid-conventions.md](data-testid-conventions.md) | | Framework patterns (React, Vue, Angular, Svelte) + centralizing IDs + production stripping | [examples.md](examples.md) | ## Golden Rules 1. **Semantic HTML first** — give elements a real role/label/accessible name so `getByRole`/`getByLabel` work; then add test IDs. …

How to install
mdr add asymmetric-al/core/playwright-frontend@sha256:c3c4196766d8550bThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
