Parameters for Mobile App Performance Testing?

Mobile app performance testing is measured as per the below parameters:

1. Device Performance

  • The application’s startup time Prozac online pharmacy is tracked along with the battery life while using the application.
  • The amount of memory consumed
  • The variation of software and hardware
  • The usage with other applications
  • An application is running in the background to check the glitches and other discrepancies. 

2. Server/API Performance

  • Here, the data to and from the server is analyzed
  • It tests all the API calls

3. Network Performance

  • Network speed like latency is studied
  • Also checked if there was any packet loss

The procedure of Mobile Application Performance Testing:

I. Line-up test intent and business requirements: It’s crucial to determine the business objective before executing the performance testing of the application. When the objectives are clear, it becomes easy to land the application at its desired position. Later, the testers work on priority to assess the application’s functions.

II. Recognize test Key Performance Indicators: Setting a benchmark is the second crucial step that shows whether your testing was successful or a failure. For mobile application performance testing, 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 existing active users per device and operating system
  • Outlined scenarios: Mostly, the testers fail because they do not prioritize the test cases and do not pre-select the major areas to evaluate the application’s performance. To avoid, outline various packet scenarios that are essential for the application’s best and most reliable performance.

III. Imitate a live testing environment: To understand the application’s user experience, a live testing environment is necessary. Hence, system emulators are used, which emulate the operating system’s essential frameworks, giving a similar display and feel of the interface to the testers.

IV. Line up the testing viewpoint with the comprehensive development procedure: Testing needs to align with an organization’s overall development structure. Continuous integration functions are a must-have to monitor the regular bug reports and regression tests allowing efficient communication, fast decision making, and cooperation of all the parties involved.

V. Lags, latency, and bandwidth of the network to be tracked: Mobile devices are connected to the internet via third-party carriers; the latency and bandwidth of the network vary from time to time and device to device. Hence, considering the network variances on top is critical while optimizing the application’s performance and improving the flawless user experience.
