A mobile phone is currently more than just a simple communication tool. It’s a gadget that can do almost everything. It can help you order food, shop online, look for simple directions, and more. You can complete all these tasks and many others using a smartphone with the help of mobile apps.

Mobile applications constitute the core of millions of businesses globally. Hence, it is important to ensure your application is of high quality. The digital landscape is speedily converting into a mobile-centric ecosystem. As a result, mobile applications need to provide unmatched performance and functionality, which puts Qalified testing into the spotlight.

Business owners and app developers need to put mobile application testing at the center of their strategy to maintain a much-needed competitive advantage. This is the only proven way through which they can cater to the current mobile-savvy audiences with all the confidence. This article explores the world of application testing. It comprehensively explains what it is and the types of tests performed. Read on to unearth more.

Application Testing Comprehensively Explained

Application testing encompasses various processes. The main one is mobile app validation. This process allows testing agencies or individuals to validate a mobile application for its usability and functionality before it’s launched in public.

The testing process helps designers and creators verify whether their application meets the expected business and technical requirements. So, what does successful mobile app testing involve? It involves testing applications across:

  • Different screen resolutions

  • Distinct networks bandwidths

  • Different operating system versions

This helps ensure that the application performs flawlessly across varying device configurations when it’s released in public. At an advanced level, testing mobile applications includes:

  • Testing application performance across distinct operating system versions

  • Validating the performance and compatibility of the application when operated on specific settings

  • Testing application appearance in both Landscape and Portrait mode

  • Testing the application’s GUI (navigation buttons, dropdown, menus, etc.) for functionality

  • Testing whether the application is compatible with mobile sensors such as GPS, Accelerometer, Gyroscope, etc.

Tests Performed

When testing mobile applications, testers must have a variety of testing techniques and skills to discover as many defects as possible in varying scenarios and environments. So, what are the most popular types of tests performed by testers? They include:

Input Test

Mobile app testers need to complete various input actions on the device when testing an application, including:

  • Multi-finger inputs: Tests all the finger gestures that the app supports.

  • Voice inputs: Helps test whether the application can correctly process inputs with external noise

  • Sensor inputs: It includes testing a variety of sensors like ambient light sensor, Gyroscope, proximity sensor, acceleration sensor, and more.

Interrupt Test

An interrupt test helps analyze the disturbances caused by different interruptions, including push notifications, which easily become overwhelming. This test helps find solutions to provide a seamless mobile experience.

Additional interruptions may include low/full battery, incoming SMS/call, alarm, etc. Testers must take into consideration app crashes, UI issues, and performance problems.

Compatibility Test

A compatibility test helps ensure the mobile application is working seamlessly on different:

  • Devices and operating systems

  • Network environments

  • Specific internal hardware specifications

Usability Test

A usability test checks an application’s user-friendliness in terms of intuitiveness and use. It helps testers to identify bugs to enhance customer experience.

Security Test

A security test prioritizes a user's personal data security. Also, it helps test application behavior under different device permission requests.

Performance Test

This type of test checks how a mobile application performs or behaves under different device permission requests.

Storage Test

A storage test checks how an application carries out its storage-related functionalities. At some point, the application needs to store, retrieve, or delete certain data on the hard disk. Also, it tests how the application behaves when there’s low or no storage in a device.

Installation Test

An installation test helps check whether an application is installing and uninstalling as expected. Also, it ensures that the application updates are working seamlessly.

Exploratory Test

An exploratory test explores different functionalities and usability of the mobile app to identify key problems. This ensures that the application works as intended.
