How the casino tests mobile apps

Shortly

The casino's mobile app isn't just about lobbies and slots. These are payments, KYC/AML, Responsible Game limits, anti-fraud, tournaments, fluffs, and complex analytics. Therefore, testing is built as a conveyor: from static checks to unit and integration tests, then e2e on real devices, "human" UX sessions, and only then - a phased release with telemetry and quick rollbacks.

1) Test strategy: "pyramid" + "device belt"

Pyramid of tests

Unit: business logic (wallet, limits, form validation).

Integration: authorization, backend gate for games, payment SDKs, fluffs.

E2E/UI: user scenarios: registration → deposit → participation in the tournament → cashout.

Device matrix

Flagship, "middle peasant," budget segment; iOS n, n-1; Android 12–15.

Different SoC/GPU, screens (5-7 ″), 60/90/120 Hz, portrait/landscape.

2) Functional testing: what is mandatory to cover

Onboarding and account: registration, login, biometrics, restoration of access.

KYC/AML: step-by-step verification, photo/video checkup, fault/retray processing.

Payments: deposits/cashouts, fees, statuses, cancellations, timeouts, re-debits.

Game lobby: catalog issuance, search/filters, favorites, provider transition.

Tournaments/missions: start, progress tracking, leaderboards, awards, deadlines.

Promos and bonuses: activations, conditions, compatibility of offers, "cooling periods."

Responsible play: time/deposit/loss limits, self-exclusion, warning blocks.

Push notifications/Deep Links: navigation to accurate screens, cold start processing.

Offline/renets: UI caching, correct return after a break.

Settings and support: language, theme, connection with support/VIP.

3) Non-functional checks: speed, stability, resource

Performance: cold start <2 seconds, lobby/wallet opening time, FPS on heavy screens.

Network: 3G/" bad 4G, "packet losses 1-5%, high RTT; degradation of stream quality without discontinuity.

Reliability: long session 60-120 min, switching between 3-5 tables/games.

Battery and memory: peak use, leaks, RSS growth after 30-50 transitions.

Accessibility: large tap zones, contrast, voice acting, VoiceOver/TalkBack.

4) Security and privacy

Transport and storage: TLS pinning, sensitive data encryption, keychain/keystore policy.

PII minimum: only the necessary fields, masking logs, auto-editing screenshots in the background.

Antifraud: protection against root/jailbreak, emulators, geo substitution; behavioral signals (multi-account, bonus hunting).

Security tests: static analysis, dynamic (OWASP MASVS), signature of responses, integration check.

5) Payments: separate test circuit

Environments and sandboxes: cards, wallets, AWS/local methods, crypto integration.

Statuses: pending/confirmed/failed/refund; retreats, idempotence, double-pay protection.

Edge cases: cancellation at the time of confirmation, network break, expired session.

UX transparency: ETA, visible commissions, cashout tracking.

6) Localization and geo-compliance

Texts and currencies: length of lines, correct separators, narrow screens.

Age/territory gates: section/stock availability, feature flags by country.

Legal texts: bonus conditions, limits, assistance contacts - visible and translated.

7) Analytics, events and data quality

Event scheme: uniform names and parameters (view_lobby, start_deposit, join_tournament).

Tracking validation: client/server event comparison, deduplication.

Cohort reports: Retention/LTV/ARPPU, traffic sources, ROI by campaign.

Hygiene: no PII in analytics; the application version and environment are always in payload.

8) Automation and infrastructure

CI/CD: builds per PR, static analysis, test packs, UI snapshot tests.

Auto-UI tests: critical paths (registration → deposit → game → cashout).

Container stands: backend pre-assembly, tournament/mission fixes, event replays.

Device cloud: farm of real devices, night runs, reports with video/logs.

9) Manual testing: where it is impossible without a person

UX sessions: "one hand," 5-minute "sprints," button misses, readability.

Promo calendar: seasonal quests, deadlines, notifications "in 10 minutes."

VIP processes: tone of correspondence, speed of decisions, non-standard cases.

10) A/B experiments and phicheflags

Ficheflags: inclusion of modules (tournaments, new wallet) by country/segment.

Experiments: alternative onboarding, promo cards, fluff rhythm; metric - target action, not clicks.

Security: instant off-switch, client rollback and configurations.

11) Phased release and monitoring

Canary stock: 1-5% of the audience → 20-30% → 100% with stable metrics.

Crash/ANR targets: threshold for rollback (e.g.> 0. 3% crash-free below base).

Performance SLO: TTI, wallet screen time, push-deeplink success.

Operational dashboards: payment conversions, KYC errors, "broken" deep links.

12) Pre-release checklists

Functional

Registration/Login/Biometrics/Recovery.
Deposit/cashout: all statuses and retrays.
Tournaments/missions/bonuses: activation, deadlines, rewards.
Responsible play: limits, pauses, self-exclusion.
Fluff/deeplinks: cold/warm start.

Nonfunctional

Cold start <2 s, stable FPS on lobby.
Network: 3G/loss/rotator Wi- Fi↔LTE, without "sticking."
Memory/battery: no leaks after 30-50 navigations.
Availability: contrast/voice acting/large font.

Security/Data

TLS pinning, secret-storage, no PII in the logs.
OWASP MASVS base check passed.
Analytics events are valid and consistent with the backend.

Reliz-management

Changes documented, schema/cache migrations verified.
Phicheflags and staged rollout are configured.
Rollback plan and on-call contact group.

13) Typical bugs and how to catch them in advance

Routing of payment SDK versions. Treated with lock files and contract tests.

KYC "quiet" errors. Integration tests with supplier mocs and negative scenarios.

Broken deep links from fluffs. Autotest for each campaign + manual cold start check.

Localization "went." Snapshots of UI (snapshot tests) for long lines, RTL languages.

Memory leaks after streams. Profiler + long sessions with switching tables.

14) Post roll-out support processes

Collection of feedback: in-app form "Report a problem" with auto-attachment of logs/version/device.

Hot fixes: a separate release branch, SLA for critical bugs (for example, 24-48 hours).

Post-morems: analysis of incidents, updating checklists and auto tests.

Casino mobile application testing is a system discipline where engineering control (autotests, performance, safety) is combined with "human" verification of UX, localization and compliance. The team that wins is:

plans releases as an experiment with phased rolling;
measures everything from TTI to responsible play limits;
holds a ready-made rollback plan.

So the product remains fast, safe and honest - and the players form trust and a long LTV.
