Difference between Stress Testing and Volume Testing

Stress Testing: Stress testing is a type of software testing that is performed to test the stability and reliability of the system under extremely heavy conditions. It also tests the robustness of the system. Volume Testing: Volume Testing is a type of software testing that is performed to test the performance or behavior of the system or application under the huge amount of data. Volume testing is also called flood testing and it is a type of performance testing. Difference between Stress Testing and Volume Testing:

Stress Testing	Volume Testing
Stress testing is software testing to check the stability and reliability of the system under heavy load.	Volume testing is software testing to check the system’s performance under huge data volume.
Stress testing checks the robustness of the system.	Volume testing checks the response time of the system.
During stress testing, load is increased continuously up to extreme point.	During volume testing, data volume in database is increased.
Stress testing focuses on the software’s stability.	Volume testing focuses on the database.
Stress testing checks security issues.	Volume testing checks data loss issues.
Stress testing makes a system capable of working in both normal and abnormal conditions.	Volume testing makes a system capable of real world usage.
Stress testing doesn’t focus on the maintenance of the system.	Volume testing reduces the maintenance cost.
