That’s where mobile performance testing makes a difference.
But before we dive into that, you should know what a mobile application is.
Mobile application software is designed to run on mobile devices like smartphones and tablets, providing users with similar services accessed on PCs. Today, technology is above everything, and mobile applications have surpassed even desktop applications in popularity.
Mobile application performance testing, however, differs from web application performance testing. It ensures your app meets high user standards by evaluating its stability, speed, and responsiveness across different devices and networks.
For example, when laptops and desktops access web applications, poor network quality, packet loss, or latency can cause minor disruptions.
In terms of mobile applications, every factor — from network quality and packet loss to device type, bandwidth, and latency — must be meticulously evaluated.
Below are different types of mobile applications:
- Browser-based applications
- Native applications
- Hybrid applications
What is Mobile App Performance Testing?
We live in the DevOps era, where rapid development and deployment are critical objectives for most organizations. Automation testing tools significantly accelerate deployment, and performance testing is essential to measure an app’s capabilities in varied environments.
Mobile app performance testing evaluates an app’s performance under different conditions, such as high traffic loads, to ensure a seamless user experience.
Why is Mobile App Performance Testing necessary?
1. User retention and satisfaction
Mobile users will likely abandon an app that crashes frequently or responds slowly. Performance testing ensures your app meets speed and stability standards, improving user satisfaction and retention.
2. Scalability and load handling
Load testing is crucial to checking the functioning of any application. The testers increase the number of virtual users for a certain period to determine the exact load threshold of the application. This process is also known as endurance/volume testing.
Load testing clarifies your system’s capacity by handling a certain number of users at a time. It also determines the application’s behavior during traffic from different geolocations. Load testing is essential to keeping your application on point and should be integrated continuously.
3. Device and network compatibility
Mobile apps run on various devices and connect via diverse network conditions. Performance testing checks the app’s responsiveness and stability across different devices, OS versions, and network speeds, ensuring consistency in user experience.
4. Resource optimization
Performance testing reveals how much battery, memory, and processing power the app consumes. This is crucial for optimizing app performance on mobile devices where resource constraints like battery life can impact the user experience.
Parameters for Mobile App Performance Testing
Mobile app performance testing is measured based on the following parameters:
1. Device performance
Tracks app startup time, battery usage, and memory consumption
Measures app performance on various software and hardware configurations
Checks the app’s interaction with background applications to identify potential glitches
2. Server/API performance
Evaluates data transfer speeds to and from the server
Analyzes API calls and their impact on app performance
3. Network performance
Studies latency, speed, and packet loss under varying network conditions
Checks packet loss to ensure data integrity
Procedure for Mobile Application Performance Testing
I. Line up test intent and business requirements
It’s crucial to determine the business objectives before executing performance testing of mobile applications. When the objectives are clear, it becomes easier to position the application as intended. Once defined, testers prioritize assessing the application’s functions.
II. Recognize Key Performance Indicators (KPIs)
Setting a benchmark is the second crucial step, indicating whether your testing was successful or not. For mobile performance testing tools, below are the KPIs that must be considered:
- Rate of error
- Highest response time
- Average response time
- Maximum number of requests
- The highest and average number of active users per device and operating system
Outlined scenarios:
Testers often fail because they do not prioritize test cases or pre-select critical areas to evaluate the application’s performance. To avoid this, outline various packet scenarios essential for achieving the best and most reliable performance.
III. Imitate a live testing environment
A live testing environment is necessary to understand the application’s user experience. System emulators simulate the operating system’s essential frameworks, providing testers with a similar display and feel of the interface.
IV. Align the testing perspective with the comprehensive development process
Testing needs to align with an organization’s overall development structure. Continuous integration functions are essential for monitoring regular bug reports and regression tests, allowing efficient communication, quick decision-making, and cooperation among all involved parties.
V. Track network lags, latency, and bandwidth
Mobile devices connect to the internet via third-party carriers, causing latency and bandwidth to fluctuate over time and across different devices. Therefore, considering network variances is critical when optimizing the application’s performance to deliver a flawless user experience.
