Mobile App Testing Services Before Android and iOS Launch

What Are Mobile App Testing Services?

Mobile app testing services involve evaluating an Android or iOS application to verify its functionality, usability, compatibility, performance and security before and after release.

Testing can be performed manually by quality assurance professionals, automatically through testing frameworks, or through a combination of both. The objective is to identify defects, confirm expected behaviour and check whether the application meets its agreed requirements.

Typical testing activities include:

• Checking registration, login and user account workflows.
• Testing navigation, forms, buttons and interactive elements.
• Validating APIs and backend communication.
• Checking compatibility across supported devices and OS versions.
• Testing application performance and network behaviour.
• Reviewing data protection and permission handling.
• Checking release builds before app-store submission.

Why Test a Mobile App Before Launch?

Finding problems before an app reaches users is generally easier and less disruptive than fixing them after release. A pre-launch testing process gives the development team an opportunity to correct defects while controlling the release schedule.

1. Reduce unexpected application crashes

Crashes may occur during login, navigation, file uploads, checkout or other important activities. Testing different user journeys helps identify conditions that cause the application to stop working.

2. Improve device compatibility

Android devices vary considerably in screen dimensions, hardware, manufacturer customisations and operating system versions. iOS devices also have different screen sizes and supported OS versions. Compatibility testing checks the app against the device range defined for the product.

3. Protect important business workflows

A business app may depend on customer registration, bookings, orders, payments, notifications or staff operations. Testing these workflows helps confirm that essential business activities function as intended.

4. Improve user experience

Usability testing can identify confusing navigation, unclear messages, difficult forms, layout problems and accessibility issues before users encounter them.

5. Identify performance issues

Testing can reveal slow screens, excessive resource usage, inefficient network requests and delays when loading large amounts of data.

6. Reduce release and maintenance risks

A documented testing process gives developers a clearer picture of application quality and helps prioritise fixes before publishing a new version.

Types of Mobile Application Testing

A complete mobile application testing plan should cover more than just opening the app and checking whether the screens load. Different testing methods examine different aspects of the product.

1. Functional Testing

Functional testing verifies whether each feature behaves according to its requirements. Testers follow expected user journeys and check the results.

Common examples include:

• User registration and login.
• Password reset and account verification.
• Profile updates and form submissions.
• Product browsing, search and filtering.
• Shopping cart and order placement.
• Appointment booking and cancellation.
• Payment confirmation and transaction history.
• Push notifications and in-app messages.

2. Android App Testing

Android testing checks how an application behaves across the supported Android versions, device manufacturers, screen resolutions and hardware configurations.

Important areas include:

• Installation, launch and application updates.
• Screen layout and responsive behaviour.
• Android permissions and notification handling.
• Back navigation and app lifecycle behaviour.
• Network switching and background operation.
• Compatibility with the declared Android version range.

3. iOS App Testing

iOS testing verifies the application’s behaviour on supported iPhone devices and iOS versions. It also checks platform-specific interactions and permission requirements.

Testing may include:

• Installation and first-time launch.
• Navigation and screen layout across supported iPhones.
• Camera, photo library and location permissions.
• Push notification behaviour.
• App backgrounding, resuming and interruption handling.
• Authentication and account management.
• Release-build behaviour on supported iOS versions.

4. Device and OS Compatibility Testing

Device compatibility testing checks whether the application works consistently across the devices and operating system versions selected for the target audience.

A testing matrix can include different screen sizes, OS versions, manufacturer interfaces, memory configurations and network conditions. The testing team should prioritise devices based on actual audience requirements rather than trying to test every device ever manufactured.

5. UI and Usability Testing

UI testing checks the visual presentation of the app, while usability testing examines how easily people can complete common tasks.

• Text alignment, spacing and visual consistency.
• Button sizes and touch interaction.
• Keyboard behaviour and form validation.
• Loading indicators and error messages.
• Dark mode or orientation behaviour, where supported.
• Accessibility labels and screen-reader support.

6. Performance Testing

Performance testing examines how the app responds under normal and demanding conditions. It can help identify slow operations, excessive resource consumption and unstable behaviour.

Typical areas include:

• Application startup time.
• Screen loading and navigation responsiveness.
• API response times.
• Memory and CPU usage.
• Battery and background resource usage.
• Behaviour during network interruptions.

7. API and Backend Testing

Most modern mobile applications communicate with backend servers through APIs. API testing verifies that requests, responses, authentication and data processing work correctly.

For example, when a customer places an order, the app should send the correct information to the backend, receive the expected response and display the correct order status.

8. Security and Privacy Testing

Security testing reviews how the app handles sensitive information, authentication, permissions and communication with backend services.

• Secure communication using appropriate HTTPS configurations.
• Authentication and session management checks.
• Appropriate storage of sensitive information.
• Permission requests and privacy-related behaviour.
• API access control and input validation.
• Review of exposed configuration and sensitive data.

Security testing should be planned according to the application’s architecture, data sensitivity and applicable requirements. A general functional test is not a substitute for a dedicated security assessment.

9. Regression Testing

Regression testing checks whether existing features continue to work after developers make changes or fix defects. This is particularly important when an application has several modules and frequent updates.

10. Installation and Update Testing

Testers should verify fresh installation, upgrades from supported previous versions, app permissions, stored data behaviour and recovery after interrupted updates where applicable.

Manual Testing vs Automated Mobile App Testing

Manual and automated testing serve different purposes. Many projects benefit from combining both approaches rather than choosing only one.

Popular Tools for Android and iOS App Testing

Testing tools depend on the application’s technology, testing objectives, development workflow and available devices. The following tools are commonly considered in mobile QA projects.

Tool availability, supported platforms, pricing and device coverage can change. The testing team should verify current product documentation before selecting a tool for a project.

Mobile App Testing Process Before Launch

A structured testing process makes it easier to identify defects, communicate findings and decide whether an application is ready for release.

Step 1: Understand the Application Requirements

Review the application purpose, user roles, features, supported devices, operating system requirements and important business workflows.

Step 2: Prepare the Test Plan

Define what needs to be tested, which devices and OS versions are in scope, how defects will be reported and what conditions must be met before release.

Step 3: Set Up the Testing Environment

Prepare suitable Android devices, iPhones, simulators or emulators, test accounts, backend environments and test data.

Step 4: Execute Functional Test Cases

Check essential features such as login, registration, navigation, payments, notifications, search, forms and data submission.

Step 5: Check Device Compatibility

Run the application on the selected device matrix and identify layout, hardware, OS and manufacturer-specific issues.

Step 6: Test APIs and Backend Workflows

Verify data exchange, authentication, API responses, error handling and server-side processing.

Step 7: Perform Performance and Security Checks

Examine loading behaviour, resource usage, network handling and relevant security and privacy controls.

Step 8: Report and Prioritise Defects

Record each issue with reproduction steps, expected behaviour, actual behaviour, device details, OS version and supporting evidence.

Step 9: Retest Fixes and Run Regression Tests

After developers resolve reported defects, verify the fixes and check related features for unexpected side effects.

Step 10: Prepare the Release Build

Verify the final release candidate, application configuration, version information, permissions, privacy disclosures and release documentation. App-store review and approval remain separate processes.

Mobile App Pre-Launch Testing Checklist

Before publishing an Android or iOS application, use a release checklist to review important workflows and technical requirements.

This checklist is a starting point, not a guarantee of app-store approval or complete security. Additional checks may be necessary depending on the app’s features, audience and industry.

Common Mobile App Issues Found Before Launch

Testing often reveals problems that are not obvious during development on a single device.

How Much Do Mobile App Testing Services Cost in India?

Mobile app testing costs depend on the number of features, Android and iOS coverage, device matrix, testing depth, automation requirements and project complexity.

The following figures are illustrative planning estimates only. They are not fixed Greap Technologies quotations or guaranteed market prices. Actual project pricing requires a review of the application and its testing requirements.

Costs may increase when testing requires more devices, extensive test automation, complex payment integrations, multiple user roles, large backend workloads or specialised security assessments. Third-party device-cloud services, paid tools, infrastructure, taxes and ongoing maintenance may be additional.

For an accurate estimate, provide the app’s feature list, technology stack, supported platforms, available builds and expected launch date.

When Should You Start Mobile App Testing?

Testing should begin during development rather than being postponed until the final day before launch.

• During development: Test individual features as they are completed.
• After module integration: Check communication between app modules and backend services.
• Before beta release: Test complete user journeys and device compatibility.
• Before public launch: Test the final release candidate and resolve critical defects.
• After launch: Monitor crashes, user feedback and production issues, then test updates before rollout.
