Mobile app performance testing is carried out to assess the performance of applications under real-world conditions. The end goal is to predict the user’s experience after the public release of the application. For testers working with mobile app performance testing tools, performance assessment usually means running multiple parallel tests to measure the system’s response for critical user journeys across a wide range of devices, locations, and networks. Performance testing also assesses the app’s response during periods of high traffic load and ensures its stability.
As such, the following are some of the use cases of mobile app performance testing tools for a mobile app tester.
Online connectivity is often a must for most mobile applications. Thus, developers need to ensure that their app is functional under different bandwidth and latency conditions—or has a useful offline or flight mode. This ensures the app remains functional for the user across a variety of situations.
Testing on Real Devices
Unlike computers, mobile devices’ screen dimensions can vary considerably from five-inch smartphones to thirteen-inch tablets. Furthermore, there are multiple technical specifications to consider, such as GPS, camera, touchscreen capacity, supported gestures, and the like. This is why it is important to test on a wide variety of real devices. Mobile app performance testing tools can offer a variety of devices and characteristics to test on to help you measure and optimize diverse mobile performance.
Simulating the Location for GPS
This is especially important for GPS-enabled apps. Testers need to ensure that GPS-enabled features work as expected when users change their location. Running functional tests on real devices in real locations is one way of achieving this.
Fragmentation in Mobile App Testing
The fragmentation of devices, OSes, and platforms is a major challenge in the mobile app testing world—consider that there are over 24,000 different Android devices in circulation today! Mobile app performance testing tools need to provide an infrastructure for testing under actual real-world conditions across a diversity of real devices and OSes. This allows developers to ensure that the app can support all the OS versions and devices that it has been made for. The types of devices that the app will be used for are usually selected beforehand, and the tests are run accordingly.
Testing for User Experience
Key criteria for user experience testing include error messages, the app’s ambiance, the intuitiveness of the interface, and navigational clarity. The app store will only accept the app after it’s been UX tested.
Complete Integration Testing
The goal of integration testing is to make sure all the app modules work together. System integration test ensures that the hardware works with the software.
Security Tests for the Applications
Most mobile apps process data from devices and store it on secure servers. To ensure the user’s privacy if the device is lost or stolen, a reliable authentication and authorization system is crucial. The goal is to secure data privacy with a system that records all events within an app. Security testing ensures the system functions reliably and consistently as expected.
Performance Across All Devices
Performance quality might differ across low-end and high-end devices. It is important to ensure that the app’s performance is consistent even in devices with lower capacities. The developer ensures that the product can handle a wide range of server loads and network conditions while being resilient to latency and bandwidth constraints.
While it may be tempting to skip performance testing when the development team is under constraints, skipping performance tests is an absolute no-no because bugs and glitches can immensely affect user experience and encourage users to switch to other options.
