What is Performance Testing and Stress Testing?

Software Testing comprises of different testing practices such as unit testing, integration testing, UAT testing, accessibility testing, etc. Every testing practice is having its significant importance and role in the software development lifecycle (SDLC).

Among the different types of testing, there a few tests that help in improving the application performance such as performance testing and stress testing. Though the purpose of these tests is to enhance the system performance, each testing practice is having a different strategy. Hence, while testing for the application’s performance, it is very crucial to understand the difference between these testing practices and perform the right one.

Though these testing types have a common purpose to enhance the application’s behavior, each test is not practiced in every situation. These having several differences and the QA teams have to understand them so that the right testing type is practiced in the right scenario.

What Is Performance Testing and What Are Its Benefits?

Performance testing is the most important software testing type that helps to manage and determine the performance of applications under a workload. Performance testing doesn’t help in finding bugs, but it removes the performance bottlenecks and enhance the major application’s performance.

Benefits of Performance Testing

• Helps in measuring the software’s stability
• Helps the teams to be aware of how the app functions under a normal load


• Helps to validate the functional features of the application

What Is Stress Testing and What Are Its Benefits?

Stress Testing is one of the testing types under performance testing that helps in detecting the application’s breaking point and also identifies the maximum load the application can handle.

In other words, stress testing determines the application’s robustness and error handling capacity under heavy workloads. Stress testing is practiced by considering more data and many users to identify the system’s behavior under pressure.

Benefits of Stress Testing

• Helps to validate if data can be corrupted when the system is overstressed.
• Verifies the delivery and error messaging feature during failure
• Assures to deliver reliable software by overcoming the risks of software failures.

Conclusion: In the process SDLC, every testing exercise is essential, and specifically to growth customer’s satisfaction and deliver applications which can be confident with the responsiveness, scalability, reliability, speed, stability etc.
