Acceptance‑Test‑First Launch Checklist: Turn One Page of Acceptance Criteria into Tests, Playables, JSON‑LD, and ASO Assets

Before you write code, reduce the feature to a single page of acceptance criteria: user, context, input, expected outcome, and edge cases. Keep it atomic — each acceptance should map to one test or one demo interaction. This discipline makes downstream artifacts repeatable and scannable by engineers, QA, and contractors.

Structure the page so that each criterion is labeled and numbered. For example: “Given I’m signed in as an editor, when I click Publish, then the article status becomes Published and a toast appears.” That single sentence contains the actors, action, expected state change, and visible confirmation you’ll use for tests, demo steps, and store copy.

Write one Playwright test per acceptance criterion. Prefer Playwright Test’s page interactions and strong assertions to keep tests deterministic. Use explicit selectors and avoid brittle text-based waits — rely on page.waitForSelector or Playwright’s built-in expect(), which reduces flakiness.

Organize tests so they can run in CI as smoke checks for each deploy. Keep tests compact: setup (login/mocks), action (clicks/inputs), assertion (UI state, network stubs). If a criterion needs backend behavior, stub network responses or use a test fixture that seeds known data.

Record the UI flow from your acceptance criteria into a small clickable demo. Use a DOM‑capture or screenshot‑with‑hotspots approach so the demo looks real and responds quickly in a browser. This demo serves sales, QA, and reviewers who need to validate the experience without installing the app.

Keep the demo under one minute and focused: each acceptance maps to a single demo scene. Where behavior depends on backend data, replace it with canned fixtures captured via DOM or light client‑side mocks so the demo remains fast and deterministic.

From the same acceptance criteria and demo metadata, author a small JSON‑LD SoftwareApplication snippet that highlights the feature as a capability/featureList. Use schema.org’s SoftwareApplication vocabulary and Google’s guidance to include name, description, screenshots, featureList, and an install/download link when relevant.

Keep the JSON‑LD minimal and factual: a short one‑line feature description per acceptance, screenshot URLs pointing to the playable, and an explicit datePublished or softwareVersion. This structured card helps search engines and assistants surface the capability and creates a single‑file machine‑readable feature summary to ship with the release.

Turn the demo screenshots and the crisp, user‑facing outcomes from acceptance criteria into store screenshots, short preview text, and a one‑line pitch. Screenshots should show the primary happy path and the visible confirmation (e.g., published state, success toast) — reviewers and users rely on those visual cues.

Follow App Store and Play Console specs precisely (resolution, localized sets, and content rules). For small teams, prioritize: 1) main hero screenshot, 2) 3 supporting screenshots showing core value, and 3) a short video or animated preview extracted from the clickable demo. These assets should be localized and use non‑cluttered captions derived straight from acceptance outcomes.
