Why Software Performance Testing is Important and its Process

Performance testing is software product testing that focuses on determining how well a system operates under a specified load. That so, it's clear that performance testing isn't just about finding and fixing errors. Software performance testing determines how well a program performs by comparing it to a set of standards and benchmarks.

Why is software performance testing necessary?

The following are some of the reasons why software performance testing is essential:

➔      Experts estimate that the number of faults in mobile apps is substantially more significant than previously stated. Network difficulties plague mobile applications, mainly when the server is overburdened. It's considerably more challenging if the apps run on shaky mobile networks. In such a circumstance, some of the issues that apps confront are:

●       Downloading problems or images that are unclear.

●       Content feeds with substantial black holes.

●       Errors in booking or payment.

●       Timeouts happen a lot.

●       Stalling and Freezing

●       Uploads that failed

➔      Client dissatisfaction caused by a poor application experience results in revenue loss. According to a survey, over 47 percent of respondents would exit the program and transact on another platform if the image was unclear.

➔      The speed of the app varies depending on the locale. It's critical to update and test an app nation by country. Internal application performance testing at various speeds and across several networks should be carried out. The app reasonably performs well in industrialized countries such as the United States, the United Kingdom, Germany, and Japan. The same app is extremely slow in developing nations like China, India, Brazil, and Southeast Asia.

➔      Performance testing examines if a system achieves high speed, scalability, and stability under high demand. When there are only 1,000 concurrent users, a system may run normally, but when there are 10,000, it may act unpredictably.

Organizations should look for performance testing technologies that can help them automate their processes. In addition, there should be no modifications to the testing environments between tests.

Process of Software Performance Testing

The process can vary substantially because performance testing can be done using various criteria. A generic process, on the other hand, might look like this:

1. Identifying the testing environment is the first step, and this comprises the testing tools and the test and production environments.

2. The process of identifying and defining acceptable performance criteria. It's important to include performance goals and metric constraints.

3. The performance test is being planned. Construct test cases based on key performance indicators.

4. Creating a test design environment and configuring it. Set aside resources to prepare the test environment, and then get started on putting it in place.

5. The test is currently running, and it is also necessary to keep an eye on the test results.

6. Retesting and re-analyzing Examine the outcomes. Retest after any fine-tuning to evaluate if performance has improved or deteriorated.

Performance testing is continuously evolving in response to changes in modern software development, and it is becoming increasingly important in establishing software confidence. It enables testers and developers to address issues in real-time and improve the performance of an application.
