Writing Playwright e2e tests for Positron requires following project-specific conventions (custom fixtures, suite IDs, tags, page objects) that are easy to get wrong, leading to flaky, broken, or unmaintainable tests.
../_test.setup, suiteId: __filename, and platform/feature tags.app, python, r, sessions, hotKeys, settings) and the app.workbench.* page object model.Write a new Playwright e2e test for the Positron console feature following the project's test conventions.

Import test, expect, and tags from ../_test.setup rather than @playwright/test, set test.use({ suiteId: __filename }), and wrap tests in a tagged test.describe block. Use fixtures like app, python, or r and interact with the UI through app.workbench page objects.
Run npx playwright test <test-name>.test.ts --project e2e-electron for a single file, or point at a directory under test/e2e/tests/ for a category. Use --grep for tag filtering, --headed to watch the browser, and --debug to step through tests.
Core fixtures include app for page objects, page for raw Playwright access, python and r for auto-started interpreters, sessions for manual session control, hotKeys for shortcuts, settings for configuration, and cleanup for file restoration. Scopes differ between worker and test level.
Flakiness usually comes from fixed page.waitForTimeout sleeps, missing afterEach cleanup, relying on interpreter state across tests, or wrapping already-retrying POM methods in toPass. Replace fixed waits with web-first assertions, expect.poll, or POM wait helpers.
Use toPass when the action itself might need reissuing, such as a click that occasionally does not register, so action and assertion retry together. Use expect.poll for non-Locator values or matchers that Locator assertions lack, like count comparisons.
