Acceptance‑Tested Microflows: 9 Interaction Specs Every Mobile MVP Must Ship to Prevent Rework

Microflows are single-purpose interaction specs: short, focused, and executable by QA or automated tests. Keep each microflow to one screen or user decision that must succeed before the next step.

When you add a microflow to a ticket or contract, include: (1) a one‑sentence intent, (2) step-by-step acceptance tests with pass/fail criteria, and (3) minimal sample data for happy and sad paths. That makes the implementation and the verification one authoritative source of truth.

Below are nine interaction specs you should ship with every mobile MVP. For each we provide intent, exact acceptance tests (step + pass/fail), developer-ready sample data, and quick notes for automation.

Treat these as canonical: include them in tickets, SOWs, and your staging test suite. They cover the usual expensive rework areas — first-run, auth, payments, network and error handling — and are intentionally small so they’re easy to automate or run manually.

Microflow 1 — First‑Run (FTUE) activation. Intent: Guide a clean device from install to a usable, permission-granted app state without blocking core value. Acceptance tests: (A) Install app on a clean device; on first open the app shows the welcome screen within 3s; (B) Onboarding step asks for only required permissions; each permission tap opens the OS prompt; (C) Decline optional permission and confirm core app path still completes. Pass: user reaches the home screen and completes the primary activation CTA. Fail: app crashes, blocks on a permission, or home screen doesn't load.

Sample data and automation notes: Provide a clean device image (device model/OS), an automation seed user (email test+firstrun@appwispr.test), and a TestFlight/Internal‑track build. Add a CI job that runs the uninstall/install/open cycle on a real or cloud device. BrowserStack and device clouds are useful to run this across OS versions to catch platform-specific first-run failures.

Microflow 4 — Payment checkout (card payment happy and failure paths). Intent: Accept a card, confirm charge, and handle a declined card without blocking the session. Acceptance tests: (A) Happy path: use a known test card number; enter card details; press Pay; payment succeeds and user lands on receipt screen with transaction id. (B) Decline path: use a decline test card; after Pay the app shows a clear inline error explaining decline with retry option and preserves form inputs. Pass: transaction id present (happy) or form preserved + retry (decline). Fail: ambiguous error modal, lost form data, or partial state where user was charged without confirmation.

Sample data and automation notes: Provide explicit test card numbers from your chosen gateway (e.g., Stripe test cards) and a staging API key. Include environment variables to switch between gateway test and live modes. Automate end-to-end runs only in staging with test tokens to avoid hitting production payment rails.

Microflow 7 — Offline read/write behavior. Intent: The app must never lose data the user created while offline and must surface correct sync states. Acceptance tests: (A) Put device in airplane mode; create content (e.g., new item); app shows a local 'Pending sync' indicator and preserves content across app restarts; (B) Restore network; app auto-syncs within defined timeout (e.g., 30s) and 'Pending' changes become 'Synced' or show conflict resolution if server rejects. Pass: no data loss and clear UI state transitions. Fail: silent data loss, overwriting user's content, or inconsistent sync UI.

Microflow 8 — Graceful error states and recoverability. Intent: All recoverable errors show clear copy, a single action to recover (retry/back), and preserve user inputs. Acceptance tests: simulate 500/502 server responses and assert the app surfaces the error copy, keeps unsent inputs, and provides a retry. Microflow 9 — Background/interrupts and app lifecycle. Intent: App must recover cleanly from backgrounding, push-notification taps, and low-memory kills. Acceptance tests: start a long running operation (upload), background the app for >60s, bring it back — operation should resume or show retriable failure; kill the app mid-upload and reopen — show a recoverable state.
