A poorly performing app can lead to disgruntled users, negative reviews, and, ultimately, lost revenue. To ensure your mobile app stands out and keeps users engaged, you need to make performance testing a priority. This blog will walk you through ten best practices for mobile app performance testing, helping you to optimize your app’s performance and deliver an exceptional experience to your users. We’ll cover everything from using real devices and testing early to automating your tests and carrying out network and location testing. So, let’s get started and take a look at the best ways to test your mobile app’s performance!

Focus on Real Devices

In the modern mobile app testing landscape, nothing quite matches the real deal. Emulators and simulators can set up a controlled testing environment, but they often fall short in mirroring the unpredictable nature of real-world use. With actual devices, you're better equipped to understand how users will engage with your app across different scenarios.

Moreover, testing on real devices gives you the chance to see how your app performs on different networks, which can vary greatly depending on the user's location and service provider. By testing on real devices connected to various networks, you can optimize your app's performance, making sure it runs smoothly even in areas with poor connectivity.

Early and Frequent Testing

Starting with testing before writing code may seem a bit out of order, but it's a great way to catch potential issues and challenges early. This way, developers can make informed decisions during the design and implementation phases, which can save a lot of time and effort down the line. It's also important to test continuously when adding new features to make sure they work as expected and don't have any unintended side effects.

Testing before, during, and after refactoring is often overlooked but has a vital role to play in maintaining the app's stability and performance. Refactoring involves modifying the code to improve its structure and maintainability, which can inadvertently introduce errors. Testing before refactoring establishes a baseline of the app's behavior, allowing developers to identify and fix any issues introduced during the refactoring process.

Before you launch a new version of your app, it’s important to test it to make sure it works as expected and doesn’t negatively impact the user experience. This means testing on a variety of devices, platforms, and network conditions to identify potential issues and ensure a smooth rollout.

Automate Your Tests

The most important benefit of test automation is the ability to execute tests consistently and repeatedly. Manual testing is important, but it can be time-consuming and error-prone. Automation eliminates these challenges, allowing for frequent testing without sacrificing accuracy. This iterative testing approach allows you to quickly detect and fix performance issues, ensuring a smooth user experience throughout the app's lifecycle.

Automation allows for testing across a wide array of devices and configurations. With the countless mobile devices on the market, manually testing on each one is a daunting and impractical endeavor. Automation, on the other hand, allows for efficient testing on multiple devices at once, covering more scenarios and identifying device-specific performance problems. This comprehensive approach ensures that your app will perform well on a variety of devices, reaching more users and keeping them satisfied.

Network and Location Testing

To run these tests effectively, it's important to use real devices or emulators that can accurately replicate real-world network conditions. This means you can test your app's performance over Wi-Fi, 3G, 4G, and even simulate network loss or intermittent connections. By testing in diverse network conditions, you can identify potential performance issues, optimize your app's network usage, and ensure a seamless user experience even in challenging network environments.

Don't forget about location testing, either. For apps that tap into location-based services, this is a must. By testing your app in various locales with different signal strengths, you can ensure it's pinpointing the user's location accurately and delivering the right services. This is particularly key for apps that handle navigation, local search, or location-based recommendations.

Conclusion

By monitoring and checking key performance indicators (KPIs), you can spot opportunities for growth and tackle any hiccups in performance before they become a headache for your users. Some of the key KPIs to keep an eye on include app load time, response time, and memory usage. By paying close attention to these numbers, you can gather valuable insights into your app's performance and pinpoint any bottlenecks or inefficiencies. Regular tests can nip potential issues in the bud, ensuring your users get a seamless experience.
