Web and Mobile App Performance Testing

31 May 2022


Imagine you plan to binge-watch your favorite Netflix series over the weekend, you stock up some drinks, order pizzas and all set to indulge in some fun time, and the app crashes due to exceptionally high traffic. Terrific, isn’t it?

App crashes, slow responsiveness, or any other performance issues can be a fretting experience to the users. Performance failures are one of the major reasons for losing users and accounts to 71% uninstalls according to a report; hence, app performance should be tested well before the release. Poor performance has been a major bottleneck in the success of an app and affects the organization’s reputation adversely.

Poor app performance affects the app at various levels, predominantly having impact on finances, reputation, and user experience. With the growing dependency on the app, organizations cannot afford to compromise on the performance and lose any of its users. Hence, performance testing becomes one of the most significant testing parameters that cannot be neglected. Let us understand more on the importance of performance testing for apps.

Understanding more about app performance testing

Performance testing is a non-functional parameter that is critical to evaluate the app’s speed, responsiveness, stability, and scalability. Without good app performance, the users may experience poor usability and lose their loyalty towards the app, hence, putting brand credibility at stake.

In today’s fast-paced world, people have no tolerance for slow working apps, hence, organizations are investing continually to improve the app performance and offer a great user experience. Suppose an app is released in the market without testing its performance, it can affect the organization severely. It is a critical testing parameter that app testing companies are constantly testing and improving to offer a seamless user experience.

Performance testing for apps is done for both, mobile apps and web apps; there are a few difference in the performance parameters you consider for both. Here is a brief on performance testing for mobile and web apps.

Mobile app performance testing: The performance of mobile apps is majorly dependent on the network connectivity, whether it is being run on 2G, 3G, 4G, or Wi-Fi. Hence, app testing for performance has to be carried out on all these conditions. Further, the app’s performance also depends on the apps running in the background which may reduce its responsiveness. Performance for these factors should be tested across devices and operating systems to ensure its performance is top-notch.

Web app performance testing: Testing web app performance varies from that of mobile apps. Here, the web app is tested for its performance across different browsers and checked for its loading time, refresh rate, and responsiveness. It has to perform equally well on all the browsers in order to stand out in the market.

Key performance identifiers for testing apps

While testing a mobile or web app, one should consider the below mentioned performance identifiers and make sure they are performing as expected.

  • App loading time
  • Maximum response time
  • Blank screen that appears while using the app
  • Refresh rate
  • Error rate
  • Withstanding the peak traffic
  • Scaling in alignment with the increasing traffic
  • Reducing screen resolution with poor network connectivity
  • Video quality
  • Loading images during session
  • Loading animations during session
  • Loading video during session
  • Stability of the app after launch
  • Maximum load at which the app crashes

All these parameters are indicators for testing the app’s performance and determines how well the app performs. In addition to the above-mentioned factors, the app should also be tested for the maximum bandwidth it can handle, effect of loading time during high traffic, is the app scalable to handle this high load, is it stable under extreme traffic.

Challenges for conducting app performance testing

There are several challenges associated with testing performance of the app, some of the predominant ones are:

  • The diverse range of testing tools is a hurdle as it makes the selection of the right performance testing tool difficult. Most of these tools focus mainly on functional testing, leaving the performance testing parameter untouched.
  • App’s performance across devices with different network connectivity varies. For example, the app may perform well on Wi-Fi or 4G network, however, its performance may be slow on devices running on 2G connectivity.
  • Device fragmentation make the performance testing even more tedious. Some apps like GPS, camera, etc., cannot give accurate results when tested over simulators or emulators. Hence, making device fragmentation one of the major issues for conducting app performance testing.
  • When thorough performance testing is conduced to create highly responsive apps, this may increase the time-to-market. To address this issue, organizations should consider ways where the performance testing is conduced quickly and doesn’t increase time-to-market.
  • The app’s performance should be testing on various device like Android, iOS, Window, web, etc., this is one of the challenging aspects of conducting app performance testing.

Conclusion

Quick response time, low refresh rate, good performance at high traffic, low loading time, or no app crash, accounts to a great app performance, which instantly connects with the audience. Conversely, slow apps with constant crashes will never appeal a user. Hence, app performance testing should be considered as a serious business and performed with utmost attention to ensure there are no errors. Only an app with great performance is liked and used by the crowd.

The growing popularity of apps is making its performance testing critical and mandatory. No matter how much you invest in functionality and security testing, without a good performance, the app can never be a success.
