Performance testing is a non-functional testing technique performed to determine the system parameters in terms of responsiveness and stability under various workloads. It measures the quality attributes of the system, such as scalability, reliability, and resource usage. Effective methods such as drafting test cases, tracking and assessing study outcomes, and improving the code are required for this testing.
Mobile app users do not have time for stuck and slow apps that crash due to heavy workloads. An app should be tested for performance stability and frequency before it is launched on the market. This is called Performance Testing. Quality testing helps to determine whether the projects meet all of the performance and reliability criteria at the planned load.
TestDel’s testers have compiled a list of guidelines and practices that will help to improve the quality of both device and web performance testing. They are as follows:
1. Determine the Business needs.
Determine the business requirements for the performance of the application. Do not spend too much time on extreme tests for an application that is going to get relatively little traffic.
2. Mention the Key Performance Indicators (KPIs) that are Relevant.
Identify specific performance measures, such as average/peak response time and the maximum number of concurrent users. These statistics can also be combined. Try to change realistic standards based on real-world scenarios.
3. Choose the Proper Tool.
There are numerous performance testing tools available. Choose the best solution according to your company’s requirements. For example, if you prefer the one with lots of code, then Gatling seems to be a better choice than JMeter for you.
4. Incorporate Performance Testing into Unit Testing.
Most of the performance testing is done at the end of the SDLC. Changes are more complex and expensive to implement in this location. Plan ahead of time and incorporate performance tests into the unit testing process. This will assist you in quickly identifying and resolving performance issues.
5. Gradually Increase the Load
As long as your goal is not to break the system, and to identify its inefficiencies, gradually raise the frequency of users. This way, you will be able to locate the point at which the server is not going to handle the load properly. Recognize the threats, analyze the factors that may have an impact on the application’s performance before beginning the testing project. Determine the conditions under which the app is to be used.
6. Look at the App from the Perspective of the End-user.
Most of the time, the QA team is concerned with server responses. However, good server results do not always imply a good user experience for your app. Make sure that your tests cover the relationship between server testing results and user interface timings. By integrating the two viewpoints, you can solve UX issues before the app is released.
7. Triage Performance Issues.
Providing the results of performance tests is fine, but those results, especially when they demonstrate failure, are not enough. The next step should be to triage the code/application and system performance and involve all parties: developers, testers, and operations personnel involved. Application Monitoring Tools can provide clarity regarding the effectiveness of triage.
Additionally, remember to avoid throwing your software “over the wall” to a separate testing organization and ensure your QA platforms match production as closely as possible. As with any profession, your efforts are only as good as the tools you use. Be sure to include a mix of manual and automated testing across all systems.
These perspectives will lead the management in highlighting all potential issues that users may continue to face even before the application’s launch.
TestDel offers software testing and quality assurance services to objectively assess the system’s operation speed, scalability, and stability. We can assist you in determining whether your app can handle heavy load as developed, thereby offering the best user quality by utilizing modern practices and approaches.
