A crucial component of the mobile app testing process is performance testing. You will be able to monitor and anticipate performance changes for peaks in connection quality (3G, 4G, 5G, LTE), the changing location of a user, higher traffic loads, and other circumstances. When it comes to mobile apps, you should test the product across a variety of platforms to determine whether the change in screen size has an impact on performance. A mobile application is a category of software that is, by definition, created to run on a mobile device, such as a tablet or a smartphone. They may be independent or web-based. Due to their one-screen limitations, minimal software capacity, and poor comprehension, mobile apps rarely support multitasking. While transferring a PC app into a mobile-based project can be an option, developers typically create mobile software from scratch to fully utilize device-specific functionality.
What is Mobile Application Testing?Mobile app testing is done to evaluate how well the application performs in one or more simulated environments to forecast what users will experience after the product is made available to the general public. Performance evaluation for testers typically entails running concurrent tests of the system response on a variety of devices, monitoring the app’s performance during periods of high traffic loads, and making sure the app is stable during periods of unstable internet connectivity and supports device-specific transactions. The following phases make up the mobile app testing process as a whole: 1. Testing for connectivity – Since the majority of mobile apps need internet access, a developer must make sure the tool works even if there isn’t any. This entails creating scenarios for users who are offline or in flight mode, testing connections with varying bandwidth, and so forth. 2. Recognizing features unique to devices – In contrast to PCs, mobile devices’ screens can range in size from 5-inch smartphones to 13-inch tablets. Other technical specifications to consider are the camera, GPS, touchscreen functionality, and the variety of supported gestures, among others. A tester should have a deeper awareness of these traits as well as how they affect the app-using experience. 3. Location stimulation – This step is essential for apps that rely on GPS. A tester must make sure that when a user changes locations, the performance of the product does not significantly change. Location simulators can be used to accomplish this. 4. UX Testing – The ability to navigate, an intuitive user interface, the appearance and feel of the app layout, error messages, and their management are essential elements of the user experience. To ensure that the software is accepted by the app store, UX testing is necessary. 5. End-to-end integration testing – System integration testing is designed to verify that the solution performs as expected in comparison to the key components of Mobile Device Management (MDM, for short) systems. 6. Security Testing – Most mobile applications process user data and store it on servers. To guarantee that a user’s privacy is not compromised if a phone is lost or stolen, testers must set up a secure authorization system, design a system for keeping track of all the activities that take place within the app, and maintain data confidentiality.
Performance indicators for testing mobile applicationsThe tester must establish benchmarks, also known as key performance indicators, to evaluate an application’s performance during the testing process (KPIs). While many different factors are taken into account while testing mobile applications, in general, the performance of the application is gauged using the primary metrics listed below: Latency/Response Time – Latency, often known as reaction time, is the amount of time between when a user submits a request and when the application responds. The response time is the amount of time it takes from when a user first verifies their payment to when their request is submitted, and processed, and a complete confirmation is given to their device, for instance, if they are making an in-app purchase and completing it. Above a certain number of concurrent users, response time increases; depending on how severe this is, you may or may not want to address this problem. Due to the unpleasant user experience caused by a slow response time, which causes customers to switch to competitors, response time is one of the most important metrics to test. Ensure that your app responds in no more than two to three seconds. Load Speed – The client user interface’s initialization and loading times, measured in seconds, are known as load speed and should be monitored under the situations listed below:
- Expected Usage – Performance testing must replicate the real-time circumstances that the application is subjected to. The application’s load speed should be checked as a starting point at the predicted number of users or requests.
- Max number of concurrent users – The maximum number of concurrent users or requests that can be made at once and the resulting load speed of the program. Keep in mind that concurrent users aren’t all accessing the same data; instead, they’re each using a different part of the application.
- Critical conditions – The load speed must also be monitored when the application is anticipated to receive a peak number of simultaneous requests. Similar to stress testing an application where its boundaries are reached, testing for critical situations involves pushing the application to its breaking point.
