Everything You Need to Know About Mobile App Testing Techniques

The market for smartphone apps needs to be more saturated. More than 2 billion apps are available in the App Store, and in the fourth quarter of 2022, more than 3 billion apps were available in the Google Play Store. According to Statista, downloads will continue to grow and will surpass 350 billion worldwide by the year 2022. The bad news is that there is a lot of competition in the market for mobile apps. Most of these apps could be of better quality, and users usually stop using them as soon as they run into issues.

Consequences include uninstalls and low ratings in the app stores. A successful applicant must be of high quality, which can only be attained with ongoing, meticulous testing and successful mobile app testing techniques.

Mobile App Testing Techniques

In contrast to other types of testing, types of testing for mobile applications distinguish themselves not only by testing levels but also by specifics of the workings of the app. For mobile applications, testing comes in 14 different flavors. Although not every application testing approach does, the following are the most popular:

Usability Testing
An application’s usability is tested to ensure that it is simple to use. A positive user experience is essential to an app’s success. Making your UX as fantastic as it can be across all devices is crucial. Each interface detail’s size, location, and purpose must be created, taking into account the unique characteristics of each platform or device.

Compatibility
Comparable to usability testing, compatibility functional testing is mainly concerned with the proper operation of the app on various mobile devices with diverse screen sizes and OS versions. Confirming the software satisfies all client needs during compatibility testing is crucial.

Interface testing
The functionality of menu items, history, settings, navigation flow, and bookmarks is tested during interface mobile app testing techniques. Interface testing is a subset of software testing that examines the effectiveness of communication between two various software systems. The web server and application server interface, as well as the application server and database server interface, are the two main parts tested in this form of testing.

Performance testing
Performance testing puts the program through many scenarios that could affect its functionality, including those with a low battery, a weak network signal, no free memory, and others. To prevent accidents, it’s critical to determine if they do or do not. The server and the client are two possible sources of performance issues. Performance evaluation looks at both.

Testing for memory leaks
Testing for memory leaks is another method for evaluating an app’s performance. In this instance, the usage of memory and memory control are the main concerns. Poor and sluggish performance is the outcome of an app’s memory management issues. The program needs to be tested in accordance with the memory constraints that apply to all devices.

Installation testing
Installation testing ensures no user-experience issues and determines whether the software installs and uninstalls correctly. Installation testing, as defined by quality assurance specialists, is a method that confirms that end users can install all software components and that the installation process is flexible and consistent. Installation testing verifies that the software was successfully installed, removed, upgraded, or restored.

Security testing
To ensure that the app secures user data, security testing is performed. It examines the app’s hacker vulnerability and verifies security requirements for authentication, authorization, session management, and other areas. Software testing with a focus on security discovers risks, hazards, and vulnerabilities in software applications and guards against harmful intrusions from outsiders. The goal of security testing is to find any flaws or vulnerabilities in the software system that could result in the loss of data, money, or reputation in the hands of workers or other outsiders of the Organization.

Interrupt testing
When an app’s operation is hampered by incoming calls, notifications, the removal of the battery, or network issues, interruption testing is used. Additionally, it provides workable solutions to guarantee a smooth user experience throughout the course of the program lifecycle. The application should ideally enter a wait state during an interrupt and restart as soon as it is over.

Load Testing
To determine whether a solution can support multiple users concurrently, load testing is conducted. For multi-user systems, which are frequently developed utilizing a client/server approach, such as web servers, this testing is especially pertinent. However, stress testing is also an option for various kinds of software systems.

Certification testing
Testing for certification determines whether the app was created in accordance with standards. For an app to be published in the app stores, certification testing is required. There are numerous levels of software testing certificates available, including entry level for applicants, intermediate level for testers with some experience, master level for experts, and expert level for professionals with years of experience.
