Performance testing is a major part of the software testing process as it confirms that an application meets the expectations concerning performance. It can augment an application by eliminating performance issues and ensure that the application is working efficiently and as per user requirements. It is extremely important for businesses to hire performance testing services for mobile applications before releasing them into the market. Since mobile users have a high rate of switching from one application to another, (if it is not performing up to their expectations) it is important for testing applications concerning performance in all possible ways. Although mobile app users are never truly satisfied with an app's performance, still testers put efforts to ensure high-quality software product releases.
Given so much importance to mobile app performance testing in meeting user expectations, some of the key elements of app testing are as follows:
Why Performance Testing is an Important Testing Technique?
One of the major reasons why mobile app testing companies opt for performance testing is to ensure that an application consistently provides its basic functions. Additionally, testers can also validate that the app loads and works quickly as per user expectations. With a holistic approach to performance testing, testers carry out the following procedures to make the best of their testing efforts:
• Check the RAM required for the app
• Verification of app speed and response-time in different circumstances
• The highest number of simultaneous app users
• Ensure app does not crash
• Test app to its limits
• Ensure affecting the performance of app – while using data and Wi-Fi connectivity
• Monitor the issues in mobile APIs
The Ultimate Mobile App Performance Testing Strategies
Testing experts measure an app’s device performance, API and network performance. All these aspects of application performance are thoroughly tested to leave no room for errors. Testers divide an app into these three categories and ensure that testing strategies are devised accordingly. Quality Assurance managers assign tasks to development teams concerning the requirements of the testing project.
1. Device Performance
Testers evaluate the start-up time app takes, battery and memory consumption of the device while using the app, and it's smooth working on different mobile devices. It also includes factors like functioning with other apps and the running of this app in the background.
2. API Performance
Testers determine the response time of an app when it is connected with the server via API. It is important to check how the app handles the data sent by services and how many API calls are generated and how does app responds when the server is down.
3. Network Performance
To evaluate network performance of an app, testing experts measure how the app works on different networks and its properties like network spend, jitters and packet loss.
Performance testing is a testing type that testers prefer carrying out during the early stages of software development. There are different tools and techniques for mobile app performance testing that help testers in carrying out testing with their best efforts.
