Performance Testing: Performance Testing is a type of software testing that is carried out to determine system performance in terms of sensitivity, reactivity, and stability under a particular workload. 

Stress Testing: Stress testing is a type of software testing that verifies the stability and reliability of the system. This test particularly determines the system’s robustness and error handling under extremely heavy load conditions. 

Difference between Performance and Stress Testing:

S. No.Performance TestingStress Testing
1.Performance testing is carried out to check the system’s performance under varying loads.Stress testing is carried out to check the behavior of the system under the sudden increased load.
2.It contains load and stress testing as components.Stress testing is the subset of performance testing.
3.It aims to determine the behavior of an application under normal conditions.It aims to ensure that putting a high load on servers for an extended period does not make them crash.
4.It checks scalability, speed, reliability, etc. of the system or software application.It only checks the stability of the system or software application.
5.In performance testing, the limit of the load is both below and above the threshold of break.In stress testing, the limit of the load is above the threshold of break.
6.It ensures that the system or software application performs properly.It ensures the security of the system under failures.
7.Performance testing is performed by uniformly varying the load.Stress testing is performed by increasing the load suddenly.
8.Load varies from lowest to highest limit uniformly.The load is directly changed from the lowest to the highest(extreme) point.
9.Performance testing is preferable when there is a requirement of validating the application’s functionality, checking the adequacy of hardware for load handling, finding, analyzing, and fixing performance issues, and more.Stress testing is needed as it aids the testing unit by testing the system in failure situations, checks for data saving by the system before it crashed, to see if any unanticipated failures potentially harm the security of the system, and more.
