Mobile App Testing

Mobile testing, or mobile app testing services, are crucial for conducting business today. Mobile QA testing refers to validating a mobile app, either iOS or Android, for its functionality, usability, and consistency before it is released to the public. Mobile app manual testing and mobile app automation testing are two important methods used to ensure the quality and reliability of a mobile application by testing the app’s functionality manually and with the help of automated tools and scripts respectively.

The QA team must test the app across numerous screen resolutions, operating system versions, and network bandwidths.

The most common business goal for a successful mobile app is to increase its user base. Users are unlikely to continue using an app if it’s faulty or challenging to use. If mobile QA testing has not been performed on an app, its users have a higher chance of encountering critical bugs while using it.

Mobile app manual testing and mobile app automation testing are two important methods used to ensure the quality and reliability of a mobile application by testing the app’s functionality manually and with the help of automated tools and scripts, respectively.

It is strongly advised to conduct both mobile app manual testing and mobile app automation testing on a mobile app before its release. Mobile app manual testing allows a human tester to interact with the app and use it in a way that may not be anticipated by automated tests, which can reveal usability or design issues. On the other hand, mobile app automation testing allows for the efficient execution of many tests in a relatively short amount of time, which can help quickly identify and fix bugs. Together, manual and automated testing provides a comprehensive approach to testing that helps ensure the app’s reliability and user-friendliness.

Types of mobile app testing services

Installability testing requires focusing on three critical aspects of mobile app testing: installation, update, and de-installation of the app.

Stress testing focuses on the ability of a system or component to handle peak loads at or beyond the limits of its anticipated or specified workloads or with reduced availability of resources such as accessible computer capacity and available bandwidth.

The functional integrity of the system should be tested while the system is under stress to find possible faults in functional processing or data inconsistencies.

Security testing should be a priority for mobile app testing. It is one of the most critical aspects of software functionality and mobile app testing services. It spots and records a product’s vulnerabilities, flaws, and dangers to avoid intruder attacks.

Additionally, it prevents information leaks, financial loss, and repercussions on an organization’s reputation and employees. Security attacks can also affect average users as they may cause personal information leaks and financial loss, among other threats. 

Performance testing focuses on the ability of a component or system to respond to user or system inputs within a specified time and under specified conditions.

Performance measurements vary according to the objectives of the test. For individual software components, performance may be measured according to CPU cycles. In contrast, for client-based systems, performance may be measured according to the time taken to respond to a particular user request.

Mobile app automation testing can undergo performance testing with the help of emulators.

Usability Testing, also known as User Experience (UX) Testing, is a mobile QA testing method for measuring how easy and user-friendly a software application is.

A small set of target end-users use software applications to expose usability defects. Usability testing mainly focuses on the user’s ease of using the application, the flexibility of the application to handle controls, and the application’s ability to meet its objectives.

Many apps need to store data locally using various data storage mechanisms such as flat files or databases. This type of mobile app testing ensures that stored data values and information are valid.

Internationalization (I18N) /Globalization testing of the application includes testing an app for different locations, dates, numbers, and currency formats and replacing actual strings with pseudo-strings.

Localization (L10N) testing includes testing an app with localized strings, images, and workflows for a particular region. For example, Russian and German words could be much longer than those in other languages. Since mobile devices have different screen sizes and resolutions, limited screen sizes may lead to problems with translated strings. These issues should be checked as standard globalization/localization tests.

Accessibility testing is performed to determine the ease users with disabilities can use a component or system. For mobile apps, this can be done using device accessibility settings and testing the app for each setting.

Accessibility guidelines are available from platform vendors, and these should be used by any mobile app testers.
