Performance Testing Concept
In today's era of the Internet of Everything, the role of the network is very important. It connects everything, and almost any information can be obtained on the web. From large enterprises, schools, governments, and countries to small individuals and self-employed persons, they use the Internet to obtain various information all the time. Acquiring and interacting with web content is very convenient and fast, so the response speed of the network becomes very important.
Furthermore, most web applications have large user bases, and they are constantly improving in the hope of adding more users. These web applications can be accessed by a large number of users at the same time and perform different operations. In this case, the performance of the application needs to be measured to understand how the application performs under high concurrent load conditions.
Also, most e-commerce, online games, and social networking sites have more or less similar functions, but on the basis of different performance parameters, judgments can be made. Therefore, performance is a crucial aspect of an application, and it is foreseeable that how the application performs under a large number of concurrent loads is the responsibility of the performance test engineer.
What is performance testing?
Performance testing, as the name suggests, is to test the quality of software performance, it is a non-functional test.
Throughout the test, the performance of the application is evaluated under the expected or higher load. During performance testing, we evaluate different performance attributes of the system, such as response time (speed), reliability, resource usage, scalability, etc.
The main purpose of performance testing is to ensure that the software can run well under the expected load, and to eliminate the performance bottleneck of the application by discovering performance problems.
Why performance testing?
The importance and necessity of performance testing is obvious for at least a few reasons:
- Provides a measure of system speed
These tests help in benchmarking parameters like response time which measures the speed of the application, which we all know is critical to the success of the application.
- Helps to evaluate the scalability of the application
Performance testing helps to check whether the application has the ability to scale to a higher user volume.
- Helps to check the robustness of the application
With stress testing, we can check the robustness of the application when the workload is higher than expected or above the application threshold.
- Helps to check the reliability of the application
Different types of performance testing are done to check whether the application is reliable and provides correct and consistent output. Performance testing, such as load testing and endurance testing, helps to assess the correctness of the system under the expected workload.
