What Is Mobile App Testing?
It is a software testing procedure that is used to evaluate mobile apps for operation, accessibility, user experience, and reliability flaws. Mobile testing can be conducted manually or by using test automation solutions like Appium. Performance testing for mobile applications before releasing it ensures that it is bug-free and prevents problems from developing in the future. This post outlines the best app testing scenarios to help you uncover bugs, malfunctions, and mistakes in your app and get it ready for launch.
Why Do We Perform App Testing – Why Is Mobile App Testing Crucial?
- App crashes account for around 71% of app uninstallations.
- Approximately half, if not more, of downloaded apps, go unused.
- Furthermore, around 70% of users exit their app because it takes too long to load.
- Around 65 percent of people avoid utilizing brands that provide a terrible mobile experience.
- If an app fails to provide the intended value, around 29% of users quit it instantly.
The statistics mentioned above put forth a clear idea that why exactly it is vital to run an Android mobile app testing A well-tested software provides a positive user experience. So you must never miss it.
Users of mobile applications discard apps that malfunction, hang, load slowly, or provide a terrible user experience in seconds. It results in negative app store reviews. Moreover, after an app is installed on a user’s device, it takes a long time to rectify the faults, re-submit the software to the app store, and wait for app users to install it. Further, users avoid utilizing apps that contain useless data or just deplete the device’s power. Also, apps should respond to a variety of events, such as device on/off, entering airplane mode, WiFi on/off or linked to another, Bluetooth, or USB.
So, to reduce difficulties and improve the app’s quality, you must undertake an effective assessment. It will attract app users and generate favorable feedback and ratings. It is the prime reason behind evaluating apps to ensure their operation, usability, and efficiency.
Mobile App Testing for Different Types of Apps
The strategy for mobile app performance testing has a significant impact on the app you are testing. Regardless of the business for which the app was developed, mobile applications are generically classified into four categories:
- Native Mobile Apps: Native mobile applications are those that are designed specifically for iOS or Android. A native iOS app is an IPA executable file that can be evaluated manually on compatible iOS devices or through test automation via the Appium and/or XCUITest frameworks. Likewise, a native Android app is an APK bundle that can be examined locally on compatible Android devices or through test automation utilizing the Appium and/or Espresso tools.
- Hybrid Native Apps: A native application shell that is free of the mobile operating system — iOS or Android — is included in hybrid mobile apps. As a result, a hybrid mobile application can use all of the operating system’s functionalities. A hybrid application is available for download from the Apple App Store or Google Play. The Appium test framework can also be used to test hybrid apps.
- Mobile Web Apps: Mobile applications are accessible by mobile native browsers such as the Mobile Android Browser, Chrome, Safari, Firefox, or device-specific mobile browsers such as Samsung Browsers, among others. These are, in essence, responsive web apps. As a result, these can be tested with the Selenium assessment framework.
- Progressive Web App (PWA): A progressive web app is a web link that may be installed on iOS and Android devices. PWAs may be found in Instagram and Twitter apps, for example. PWAs allow you to build a shortcut to these applications and install them without having to visit either Apple App Store or Google Play.
Understanding Different Stages of Mobile App Testing
