1 Understand the causes

Before you can test your app for crashes and freezes, it is important to understand what can cause them. Crashes are when your app unexpectedly stops working and exits, while freezes are when the app becomes unresponsive. Common causes of crashes and freezes include memory leaks, bad network conditions, unhandled exceptions, UI thread blocking, and compatibility issues. Memory leaks occur when your app allocates memory but does not release it properly, leading to memory exhaustion and system instability. Bad network conditions arise when your app relies on network connectivity but does not handle errors or interruptions gracefully. Unhandled exceptions happen when your app encounters an unexpected situation or error that is not caught or handled by your code. UI thread blocking occurs when long-running or intensive tasks are performed on the main thread responsible for updating the user interface. Finally, compatibility issues can arise when your app does not work well with different devices, operating systems, screen sizes, or orientations.

One thing I've found helpful in my experience testing mobile applications for crashes and freezes is implementing a robust combination of manual and automated testing. One time at work, we faced a challenging situation where our mobile app would frequently crash, causing frustration among users. To address this issue, we began by conducting thorough manual testing. Our team explored various user scenarios, trying to replicate the conditions under which crashes occurred. This involved using the app in different network environments, on various devices, and during different stages of operation. By systematically documenting our findings, we gained valuable insights into the patterns and triggers of the crashes.

2 Choose the right tools

Testing your app for crashes and freezes requires the use of the right tools that can simulate different scenarios, monitor your app's behavior, and collect data. Emulators and simulators are software programs that imitate the characteristics of real devices, allowing you to test your app on various platforms, versions, and configurations without having to own or access physical devices. Crash reporting tools capture and report the details of crashes that occur in your app, such as stack trace, device information, user actions, and logs. Debugging tools enable you to inspect and modify your app's code, state, and variables at runtime. Profiling tools measure and analyze your app's performance, resource usage, and behavior. All these tools can help you identify the frequency, severity, location of crashes, user impact and feedback, errors and bugs causing crashes and freezes in your app as well as bottlenecks and inefficiencies resulting in crashes and freezes.

3 Follow the best practices

To test your app for crashes and freezes effectively, it's important to follow some best practices that can help you prevent, detect, and resolve these issues. Test your app early and often throughout the development cycle to catch and fix problems before they become more complex. Additionally, use real devices when testing as they provide more accurate feedback on your app's performance and behavior. Furthermore, you should test your app on different conditions such as low memory, low battery, poor network, high load, orientation change, or app switching. Finally, test your app on different users that represent your target audience to receive valuable feedback on usability, functionality, and reliability. With the right tools and best practices in hand, you can test your app for crashes and freezes efficiently and improve its performance and reputation.

The most effective way to test mobile applications for crashes and freezes is through rigorous performance testing, including stress testing and edge-case scenarios. Utilize testing frameworks, simulate various device conditions, and monitor system resources to identify potential issues. Additionally, beta testing with real users can provide valuable insights into real-world usage scenarios. Also, I would recommend to use some sort of crash tracking tools like firebase crashlytics for more insights.
