--- name: recording-browser-flow-as-test description: Execute a user flow step-by-step in Cursor's built-in browser while documenting each action, then emit a Playwright test that replays the same flow using stable selectors derived from the accessibility tree. user-invocable: true --- # Recording Browser Flow as Playwright Test Use the **browser** MCP as a **recorder**: every navigation, click, fill, and keypress becomes a row in a script. The agent then translates that trace into a **Playwright** test file in the repo (or a snippet to paste into an existing spec). This is Cursor-native because it combines `browser_snapshot` (refs + roles + names) with structured actions — not a separate recorder extension. ## Prerequisites - Target app reachable (e.g. dev server running); use `finding-dev-server-url` if needed. - Repo has or will have Playwright installed (`@playwright/test`). If not, add it with `adding-e2e-tests` or the project’s standard setup. ## Recording workflow ### 1. Define the flow One sentence scope, e.g. “Log in, open Settings, toggle dark mode, save.” ### 2. For each step, in order 1. **`browser_snapshot`** — get the accessibility tree and element refs. 2. Choose the **smallest** interaction: - `browser_click` with ref from snapshot (not coordinate clicks unless required). - `browser_fill` or `browser_type` for inputs. - `browser_select_option` for selects. - `browser_navigate` for full URL changes. 3. **Log the step** in a structured list the main agent keeps: - Step number - Action verb (`navigate`, `click`, `fill`, `press`, `select`) - **Locator strategy for Playwright** — prefer: - `getByRole('button', { name: '...' })` - `getByLabel('...')` - `getByPlaceholder('...')` - `getByTestId('...')` if the app uses test IDs - Value (for fills), URL (for navigates) - Optional: short assertion (“expect URL to contain `/settings`”) 4. After actions that change the DOM or navigate, take a **new** `browser_snapshot` before the next interaction. 5. If the flow must wait for async content, use `browser_wait_for` or short incremental waits per `cursor-ide-browser` guidance — then snapshot again. ### 3. Add assertions From the final snapshot and URL, add **at least**: - `expect(page).toHaveURL(...)` or URL fragment check - One **visible** outcome: text, role, or test id ### 4. Generate Playwright output Emit a test file, e.g. `tests/recorded/.spec.ts`, containing: - `test.describe` and `test('...', async ({ page }) => { ... })` - Steps as `await page.goto(...)`, `await page.getByRole(...).click()`, etc. - **No** raw snapshot refs in the final file — they are session-specific. ### 5. Run and harden ```bash npx playwright test tests/recorded/.spec.ts ``` Fix flakiness: prefer `expect(locator).toBeVisible()` before clicks, use `toPass()` retries for async lists, avoid arbitrary `waitForTimeout` except as last resort. ## Tips - **Stable selectors**: roles and accessible names beat CSS from devtools. Add `data-testid` in app code if names are ambiguous. - **Auth**: if the flow needs login, use env vars for test credentials or Playwright `storageState` — never commit secrets. - **Parallel runs**: ensure test data does not collide with other tests. ## When not to use - Flows that require manual 2FA, captchas, or email links — stop and ask the user for a test bypass or mock.
