What are the best application performance testing services for mobile applications?

Some of the testing tools like Apache JMeter, Blaze meter, Android Profiler etc. can be used mobile application performance testing services.

WebLOAD is load testing tool, performance testing, stress test web applications. This web and mobile load testing and analysis tool is from RadView Software. Load testing tool WebLOAD combines performance, scalability, and integrity as a single process for the verification of web and mobile applications.

Non functional testing. Check with data and test high traffic volume during rush hours. Simulate thousands of customers one at a time, that helps to identify crash points, responsive time and stability.

field testing, field testing, field testing. look at what is used, what is not; what is not used as as superfluous (nobody uses), what is not used as probably not working properly (nobody uses on just one device) and wait for things that only break at 1000 users, 10,000, 100,000 and millions of users but worked perfectly before then…

One of my favorite examples of all time is the chaos monkey from Netflix. Chaos monkey basically randomly went around disabling production Netflix services to see if they could survive outages. Incredibly effective and also hilarious.

- Create stress test scenarios that push your app beyond its limits, such as rapidly increasing concurrent users or overwhelming server requests. - Analyze how your app behaves under stress to fortify it against crashes or performance degradation in high-pressure situations.

Continuous performance monitoring is essential for post-launch app health. It tracks performance over time, identifies trends, and detects issues before they impact users. With alerts for slowdowns or crashes, you can proactively address problems, ensuring a smooth app experience for all users.

When testing mobile apps, consider factors like network conditions, device variability, and user behavior. Utilize real-world scenarios, automate testing wherever possible, and prioritize performance metrics such as response time and resource usage. Continuous testing throughout the development cycle is key in identifying and addressing performance issues early.

- Employ user simulation tools like Gatling or Selenium to replicate diverse user behaviors and interactions with your app. - Fine-tune your app's performance based on insights gathered from user simulation tests, optimizing features for maximum usability and engagement.

Too late at this time, make sure there are documented unit tests, and all searching is done sensibly, and not looking through an unsorted list, which grown and grows. O (N) lookup, or O (Log N).

Throttle your internet and see how your app behaves. There are many users that have 2G or 3G connections and the app experience may be unusable under these conditions if your app uses a lot of network resources innefficently.

Network testing in mobile app development evaluates how an app behaves under different network conditions. It examines factors like latency, bandwidth, and reliability to ensure seamless performance across varying connectivity levels. By simulating scenarios such as slow or intermittent connections, network testing helps identify potential issues like slow loading times or data synchronization errors. It's crucial for delivering an app that performs consistently and reliably, regardless of network conditions, enhancing user experience and satisfaction.

Tools like Battery Historian (for Android) and Xcode Instruments (for iOS) provide insights into your app's battery usage and power consumption patterns. Battery usage testing helps identify power-hungry components and optimize energy efficiency for prolonged battery life.

- Employ battery profiling tools like Battery Historian (Android) or Instruments (iOS) to analyze your app's energy consumption and identify power-hungry components. - Optimize resource-intensive processes and minimize background activity to prolong device battery life and enhance user satisfaction.

The best application performance testing services for mobile applications include Firebase Test Lab and AWS Device Farm, offering comprehensive performance testing capabilities across various devices and network conditions, along with detailed analytics and reporting for optimizing app performance.

Additionally, consider factors such as ease of use, scalability, integration capabilities with your existing toolchain, support for automation and CI/CD workflows, and pricing model (e.g., pay-per-use, subscription). Choose performance testing services that align with your project requirements, budget, and long-term goals for app performance optimization.
