2. Performance Testing

Performance testing assesses how an application functions under different settings and ensures that the application doesn’t glitch under non-optimal circumstances. Your mobile application users have high expectations for how the application ought to respond to every movement they perform inside the application. From application sending off to execution and leaving the app open in the background while transitioning between applications, the expected turnaround time of each event is critical. If the application doesn’t respond to these triggers for a few seconds, your app users might become frustrated and may eliminate the application.

You should conduct automated mobile app testing to recognize limitations in your applications.


  • Ensures that the application effectively executes installation and sign-in time, battery use, and memory utilization.
  • Deferrals, errors, and breaks in getting data or introducing network-actuated highlights are undeniably assessed.
  • Recognizes the underlying drivers of information transfer issues from the back finish to the front end.
  • Optimizes the built-in backup and recovery features, which can save or recuperate your user data in case of information loss.

3. Localization Testing

This method is very beneficial among the various techniques of app testing. This type of mobile app testing is intended to evaluate features that are reliant on an app’s geographic area and are compatible with their language and cultural preferences. Most apps contain localized features for user convenience and adhere to local legal and regulatory standards because they aim to attract a worldwide user base. These characteristics range from supporting many languages to allowing commerce in local currencies.


  • It permits mobile development teams to reach a more extensive audience while delivering high-quality products to the market.
  • It benefits your project teams over competitors that don’t use localization capabilities to improve usability.
  • It can guarantee that the portable application’s date, time, and other local settings are suitable.
  • It supports adopting mobile applications in specific nations, allowing firms to be seen as brands worldwide.

4. Compatibility Testing

Compatibility testing is a kind of mobile application testing that focuses on the application’s non-functional features, such as measuring the compatibility of mobile apps with specified software, network, and hardware requirements. It ensures that your application runs smoothly across several operating systems, browsers, and models. The testing team would check the application’s interoperability with various operating systems such as Android, iOS, and Windows.


  • It helps developers address challenges connected with mobile application compatibility between platforms and deliver non-native mobile applications.
  • Developers can detect Errors in mobile applications before they reach users.
  • It allows us to assess mobile applications’ usability, scalability, and stability to maximize user happiness.

5. Installation Testing

Installation testing is analyzing the flawless installation and removal of a mobile app. This testing confirms that your program is adequately downloaded from the App Store or Google Play. The user’s first experience with the finished product is during the installation of the mobile app, and any problem during this step can dissuade the user from accessing the app.

The primary aim of installation testing should be an error-free and seamless installation of your mobile app. It is critical to include installation testing as part of the mobile app testing process before each version release to avoid such failures.


  • Allows easy toggling between several apps while the mobile app is being installed.
  • Perform all of these tasks after installing the software and evaluate whether the installation causes breakdowns, hanging problems, or glitches to the user.
  • It determines whether the installation procedure of a specific mobile app adheres to the client and industry practices.
  • If the installation succeeds well, there is a high possibility that the remaining half of the activities will run smoothly.

6. Security Testing

App users are increasingly concerned about data security risks. Most netizens are worried about their digital privacy and the confidentiality of their personal information. Mobile app test automation is essential to ensure an app is successful.

Almost every app requires some personal information; tests must be performed to reinforce them to ensure data privacy. Indeed, 81% of users said they would delete an app and switch providers due to security concerns, implying that customers want to ensure that their data or sensitive information would not be compromised.


  • It provides the safety and security of the mobile application for its end users and identifies flaws before they become security problems.
  • It assists enterprises in preventing data loss, thwarting data theft efforts, and securing data.
  • It aids in the detection of fatal defects in mobile application layout during development and the discovery of core security threats.

7. Interruption Testing

Every app must coexist with other device features when used by actual people. Every software must be optimized to handle these device operations while running. Interruption testing assures that an app manages interruptions without failing or anomaly and analyzes how an app behaves when it encounters an unforeseen stoppage.

Interruptions like receiving messages and calls should not have a detrimental influence on the performance or functionality of the mobile app, and it should be optimized to deal with device functions.


  • This testing ensures that, whether it’s a mobile alert, app upgrade notification, or low battery warning, the app will resume regular operation when you do the action.
  • Mobile app test automation enables those warnings and notifications, such as SMS received or clock alarms can appear in the header without affecting the app.
  • When a higher-priority activity starts while the app runs in the background, it is tested to check if things return to normal after the interruption.

8. Automated Testing

Automated testing is a testing approach in which testers use scripts to automate the testing process of mobile apps, allowing teams to test quicker and more effectively. This testing can encompass the process of establishing, maintaining, and building successful testing scripts, as well as integrating or aligning current business procedures. Automated testing is critical to creating high-quality software.


  • Automated testing enables technology teams to use testing tools better while reducing the likelihood of human mistakes in testing processes.
  • It helps teams modify the testing technique, making it simpler and more efficient, and enables automated testing to detect more errors.
  • UI testing automation is cost-effective and can save significant time and effort in the long run.

9. Memory Leak Testing

A memory leak occurs when an app cannot respond to the memory it has obtained for the momentary operation, causing the app’s allocated memory to deplete and the app to cease functioning. Each application ought to be assessed for this issue since memory leaks are brought on by coding botches and can lead an application to be ended, assuming it is frequently utilized or launched. Testers can assess application execution on devices with differing memory limits and change the program to work appropriately in every setup.


  • Memory spill testing reveals weaknesses rapidly and protects information.
  • Code issues cause memory spills. Consequently, this testing keeps up with applications mistake-free.
  • This testing permits specialists to assess application execution on telephones with different memory limits and change the application to work effectively in every arrangement.

10. Usability Testing

Usability testing, also known as user experience or exploratory testing, is a critical UI testing automation that determines how user-friendly and intuitive the app is. This testing lacks a rigid methodology. Therefore QA testers frequently utilize their knowledge of user requirements to determine whether the application is up to par. As a result, assessing the application’s user-friendliness, responsiveness, and overall layout and design is critical.


  • The likelihood of product failure is lowered since design specialists may focus on the critical needs from the end customer’s viewpoint.
