The popularity of mobile applications is steadily growing, and the world is swiftly moving in that direction. In addition, mobile application users have increased by 58 per cent in recent years. According to the study, about 4.6 billion individuals use mobile applications around the world.

It shows that the number of users is growing by the day. As a result, business owners are favouring the concept of mobile app development.

We’re talking about the mobile app testing checklist that needs to be completed before the launch. Furthermore, innovative and engaging mobile applications propel organizations to new heights, while customers reject apps that do not meet their expectations. In addition, in today’s competitive market, you must be astute enough to maximize your client’s reach. As a result of our experience in the sector, we’ve discovered that the majority of applications are rejected due to bugs, so let’s take a brief look at the checklist that must be kept in mind while testing. Even if the quality assurance team only has a limited amount of time to test, the checklist will be useful.

We’ll go over a step-by-step mobile app testing checklist in this article.

1. Checklist for Mobile Application Testing

Step 1: Test for cross-platform compatibility in your app.

Your Android application might work fine on Oreo (Android 10) but not on Marshmallow (Android 6.0). This is where cross-platform testing becomes useful.

You should test your app on every potential configuration of operating systems, screen sizes, and dimensions that your app’s users may utilize. This guarantees that the app behaves consistently across all platforms.

Step 2: Test your app in all conceivable configurations and parameters.

Many functions, both in-app and on the mobile device, interact with a mobile app. All of the various options and configurations should be compatible with the app. Screen resolution, orientation, multiple operating system versions, camera, motion sensor, and so on are examples of these.

Step 3: Your test cases should be tailored to the type of app you are testing.

There are three types of mobile apps: native, web, and hybrid.

• Web applications Testing

Web apps should be tested for UI to guarantee that all app components are interconnected for different screens and resolutions. They should be optimised for mobile browsing and server-driven. Since mobile apps have limited storage space and power source, perform memory and battery usage tests. Avoid using JavaScript excessively as this may drain the battery of your mobile device.

• Native and Hybrid Applications Testing

Native and hybrid apps have identical functionality and thus testing approaches, despite being powered by distinct technology. Run functional tests to verify essential aspects like screen orientation, gestures, compatibility, connectivity, performance, and disruptions like calls and push notifications.

Step 4: Thoroughly test your app’s user interface.

Front-end testing validates the features available on an app’s UI – testers examine the GUI’s functionality. This includes testing the end-menus, user’s dropdowns, navigation buttons and gestures, forms, and other features.

Front-end testing ensures that the app under test works properly on various browsers and devices. For comprehensive front-end testing, run unit, regression, performance, integration, and acceptance tests on the app.

Step 5: Check your app for back-end/database functionality.

Back-end or database testing is concerned with the mobile app’s server-side. The majority of mobile apps today are API-driven. The data is loaded into the UI via REST APIs. Monitor the app’s requests and responses with a proxy. Conduct SQL, performance, and security testing to avoid deadlocks, data leakage, and other issues.

Step 6: Run all positive and negative test cases related to storage/memory usage in your app.

Mobile users expect to be able to access all of their essential apps while on the go. However, the devices do not have enough storage to accommodate the installation of high-resolution apps.

With each new release, keep an eye on the app size. You should not be in a position where the end user is unable to download the app due to its size.

Step 7: Test your app on all networks that users may use.

Run the app under various network conditions to assess its performance in terms of signal strength and data transition. Consider these factors when testing network performance:

• Jitters

This occurs when data collecting is delayed. Because data is transmitted in packets, packets may disperse as they travel from the transmitter to the receiver. As a result, the data becomes scrambled, which is referred to as jitters. In such circumstances, the app should prompt the user to resend the data or wait for a response from the system.

• Data Loss 

Ensure that the app resends the data request or notifies the end-user in the event of a total packet loss. Instead of keeping the user waiting, the app should encourage them to try again.

• Network Type and Speed

Network speeds fluctuate from time to time; this should, This does not degrade the user experience. Test the app on various networks and speeds to see how it performs. Check how the app reacts when it switches from mobile data to Wi-Fi and back.

Step 8: User journeys should be tested on your mobile app.

An excellent mobile app workflow is one that requires no description and can be grasped right away. The user flow may alter depending on how the app reacts to various devices and operating systems.

For example, an user can log in to an app using a fingerprint, face identification, or username and password. Test all available features in order to provide users with the greatest possible digital experience.

Step 9: Ascertain that your application is both safe and secure for users.

Mobile app security can appear scary due to the various operating system components. You can, however, secure your mobile app by following these simple steps.

1. Protect the database and source code.
2. Validate the data entered.
3. Test for Penetration
4. Encryption should be used
5.  Avoid Injection on the Client Side
6. Use HTTPS.
7.  Safeguard Data Stored on Local Devices
8. Automating Mobile Apps

2. Types of Mobile App Testing

• Usability Testing: Ensures that the software is simple to use and that the user experience is what you want.
• Compatibility Testing: Ensures that the app works properly on a variety of devices, browsers, screen sizes, and operating systems.
• Interface Testing: Menu options, navigation, gestures, transitions, buttons, history, and settings were all put to the test.
• Services Testing: The app’s online and offline modes are being tested.
• Resource Testing: Validating issues with the local database.
• Performance Testing: Switching from mobile data to WIFI, data sharing, battery usage, and so forth are all good ways to test the app’s performance.
• Operational Testing: Backups are being tested in case data is lost during app upgrades.
• Installation Testing: Verifying the app’s installation and removal.
• Security Testing: The mobile app’s data protection functionality is being tested.

3. Advantages of Mobile App Testing Checklist

• Ensures that the application runs smoothly.
• A High-quality product for the users.
• Increased users’ participation.
• Increased both sales and revenue. 
• Enhances the reputation of the organisation.

4. Conclusion

These checklists were built in order to develop a bug-free and productive application. A minor error can often be transformed into a major blunder. As a result, the quality assurance team must continually be proactive and double-check the application against the checklist. As a result, these checklists improve a mobile application’s performance.

Moreover, testing is an integral component of the development process, and failing to do so will lead to the application’s demise. As a result, quality should always take precedence, which can only be achieved through sound testing. We’ll continue to introduce new and fascinating concepts to the process. We consistently place a premium on raising product visibility in terms of quality and dependability. Contact TestDel for more information.
