What mobile app testing services include

What do mobile app testing services include?

Mobile app testing services check that an iOS or Android app works correctly, looks right and performs well on the devices, OS versions and networks your users have. A mobile app testing service usually combines manual testing on real devices, automated regression tests, and release checks against Apple and Google store rules.

With CloudOryx, you get:

  • A device and OS test matrix based on your analytics.
  • Test cases for your core user journeys, stored in your tools.
  • Manual functional, UI and exploratory testing on every release.
  • Automated regression for stable flows, run in your pipeline.
  • Defect reports with device, OS version, steps, screen recordings and logs.
  • A release recommendation and app store checklist before each submission.

Why mobile testing is different

Why is mobile app testing different from web testing?

Mobile apps run on thousands of device models, several OS versions and unstable networks, and they are constantly interrupted by calls, notifications and low battery. A web page that works in three browsers is fairly predictable. A mobile app can behave differently on two phones from the same brand.

The main differences are:

  • Device fragmentation: screen sizes, notches, chipsets and memory vary widely, especially on Android.
  • OS versions and permissions: each iOS and Android release changes how permissions, background work and notifications behave.
  • Real-world conditions: weak signal, switching between Wi-Fi and mobile data, airplane mode and low battery.
  • Interruptions: calls, alarms, app switching and screen rotation in the middle of a task.
  • Store gatekeepers: Apple and Google review every release and can reject builds that crash or break their rules.

How we choose devices and OS versions

How do you decide which devices and OS versions to test?

We build a device matrix from your real user data, not from a generic list. We pull device models, OS versions and screen sizes from your analytics or app store console, then group them into tiers so the most-used devices get the deepest testing.

TierWhat it includesTesting depth
Tier 1Devices and OS versions that cover most of your active usersFull functional, regression and exploratory testing on real devices
Tier 2Older OS versions and less common screen sizes still in useCore flows and layout checks, often in cloud device labs
Tier 3Edge cases: tablets, foldables, the oldest supported OSSmoke tests and targeted checks before major releases

If your app is new and has no analytics yet, we start from current market share in your target country and adjust after the first months of real usage. We review the matrix every quarter, because new phones and OS versions arrive every year.

Types of mobile app testing we run

What types of mobile app testing do you run?

Our mobile app testing services include the mix of tests your release needs, from quick smoke checks to full regression. The table shows what each type of testing catches.

Test typeWhat it catches
Functional testingFeatures that don’t work as specified: sign-up, payments, search, forms
UI and layout testingCut-off text, overlapping buttons, notch and dark mode problems
Compatibility testingBugs that appear only on certain devices, OS versions or screen sizes
Performance testingSlow launch, laggy scrolling, memory leaks and crashes under load
Network testingFailures on weak signal, offline mode and switching between networks
Battery and resource testingApps that drain battery, overheat devices or use too much data
Interruption testingLost data or crashes after calls, notifications, rotation or app switching
Install and update testingProblems with fresh installs, upgrades from old versions and data migration
Push notification testingNotifications that don’t arrive, open the wrong screen or ignore settings

Most mobile apps also depend on APIs. We test those too, as part of our wider outsourced QA testing services.

Real devices, emulators and cloud labs

Should you test on real devices, emulators or cloud device labs?

Use all three, each for what it does best. As a mobile testing services company, we combine them in one plan. Emulators and simulators are fast and cheap for early checks. Real devices catch hardware, performance and battery problems that emulators miss. Cloud device labs give you wide coverage of models you don’t own.

OptionBest forLimits
Emulators and simulatorsEarly feature checks, automated tests during developmentMiss real performance, camera, sensors and battery behavior
Physical devicesTier 1 testing, performance, gestures, camera and notificationsCostly to keep many models up to date
Cloud device labsWide coverage of Tier 2 and Tier 3 devicesNetwork conditions and some hardware features are harder to test

Native, React Native and Flutter apps

Do you test native, React Native and Flutter apps?

Yes. We test native iOS (Swift) and Android (Kotlin) apps as well as cross-platform apps built with React Native and Flutter. Cross-platform apps share most of their code, but they still need testing on both platforms, because each OS handles permissions, gestures, fonts and navigation differently.

For cross-platform apps, we pay extra attention to:

  • Platform-specific screens, such as permission prompts and share sheets.
  • Back button and gesture navigation on Android.
  • Font scaling and text wrapping on both platforms.
  • Native modules, such as payments, camera and maps, that behave differently on each OS.

Mobile test automation

How do you automate mobile app testing?

We automate stable, repeated mobile flows with Appium and the platform tools your developers already use, such as XCUITest for iOS and Espresso for Android. Automated tests run on emulators for fast feedback and on real or cloud devices before release.

Mobile automation costs more to build and maintain than web automation, so we focus it on flows that matter most, such as login, onboarding, checkout and core features. Our test automation services page explains how we choose what to automate and how we keep tests stable.

App store release checklist

What should you check before submitting to the App Store or Google Play?

Before every submission, check that the app doesn’t crash, every feature reviewers can reach works, and your store listing, privacy details and permissions match what the app actually does. Crashes and incomplete features fall under Apple’s App Completeness rule, one of the most common reasons apps are rejected.

Our release checklist covers:

  1. No crashes or freezes on Tier 1 devices across the main journeys.
  2. No placeholder text, test data, broken links or “coming soon” screens.
  3. A working demo account for reviewers if the app needs a login.
  4. Screenshots and descriptions that match the current build.
  5. Privacy details and data safety answers that match how the app uses data.
  6. Permission prompts that clearly explain why each permission is needed.
  7. An account deletion option inside the app, if users can create accounts.
  8. Upgrade testing from the previous store version, so existing users keep their data.

Apple publishes the full rules in its App Store Review Guidelines. We check your build against them before you submit.

Mobile security and accessibility basics

How do you cover mobile security and accessibility?

We cover the security and accessibility checks every release should pass, and we flag deeper issues for specialist review. Security checks follow the OWASP Mobile Application Security (MAS) project, which sets the common baseline for mobile app security testing.

Security basics we check:

  • Sensitive data is not stored in plain text on the device or shown in logs.
  • Sessions expire and log out correctly.
  • The app uses secure connections for all network traffic.
  • Screens with sensitive data are hidden in the app switcher where needed.

Accessibility checks: we test key journeys with VoiceOver on iOS and TalkBack on Android, check large text settings, color contrast and touch target sizes. For healthcare apps, CloudOryx is not HIPAA certified, so we agree data rules with you in writing and test with masked or synthetic data only.

Sample mobile test report

What does a mobile test report look like?

After each test cycle you get a short summary that your product owner can read in two minutes, plus detailed defects in your tracker. Here is an illustrative example of the summary format (not a real client report):

Release: 3.8.0 (build 412) Cycle: 2 days Devices tested: 9 real + 14 cloud OS: iOS 17-18, Android 12-15 Recommendation: GO WITH KNOWN ISSUES Defects found: Critical 0 | High 2 | Medium 5 | Low 7 Fixed and retested this cycle: 11 Open High issues: – Android 12: photo upload fails on slow 3G (workaround: retry) – iPad: checkout button hidden in horizontal view on 11″ models Not tested: in-app purchase on live store (sandbox only) Next cycle: regression on 3.8.1 after fixes

The “not tested” line matters. A good report says clearly what was outside the test scope, so nobody assumes coverage that didn’t happen.

You can work with us as a dedicated mobile QA team, by project before a launch, or on demand before each release. See our QA outsourcing services for how each model works, or the QA as a Service page for our full testing range.

01

Which iOS and Android versions should we support and test?

Support the versions your users actually run, based on your analytics, and test the newest versions as soon as betas are available. Many teams support the current and previous two major iOS versions and a wider range on Android, where older versions stay in use longer. We confirm the exact range with you when building the device matrix.

02

How long does a mobile app test cycle take?

A focused regression cycle on a typical app usually takes one to three days, depending on the number of features, platforms and devices in scope. A first full test of a new app takes longer, because test cases and the device matrix must be built first. Automation shortens later cycles for stable flows.

03

Can you test beta builds from TestFlight or Firebase?

Yes. We install builds through TestFlight for iOS and through Firebase App Distribution, the Google Play internal testing track or direct APK files for Android. Testing pre-release builds lets us catch problems before they reach store review or real users, and it fits naturally into sprint-based release cycles.

04

Do you test tablets, foldables and wearables?

We test tablets and foldable phones when your users have them, because layouts often break on larger or changing screens. Wearable and TV apps need specific devices and setups, so we scope them separately. If your analytics show very few tablet users, we usually cover them with smoke tests in cloud device labs instead.

05

Can you help if Apple or Google rejects our app?

Yes. We read the rejection notice, reproduce the problem on the right device and OS version, and give your developers a clear defect report. Once the fix is in, we retest the affected area and run the release checklist again before you resubmit, so the same issue doesn’t come back in the next review.

06

Do you test the APIs behind our mobile app?

Yes. Many mobile bugs actually start in the backend, such as slow responses, missing fields or wrong error messages. We test the APIs your app depends on, including how the app behaves when an API is slow, returns an error or is unavailable, so users see a helpful message instead of a crash. See our API testing services for details.
