Stress Testing in Software Engineering
- Stress testing is also known as “Endurance Testing”.
- Stress testing is a type of performance testing that evaluates the system’s reliability and stability.
- It checks that how the system works under the load conditions ( normal and at peak point). This testing ensure that system would not crash under critical situations.
- The main aim of the stress testing is to find the limit at which the system or software or hardware breaks.
- This testing tests on the normal operating point and also at the high load point and tests how the system behave at those heavy points.
- Software testers performed this testing to ensure that system’s performance/ behavior and working under load and stress conditions.
- It determines the breaking point of the system, that is just before its system’s crash.
- For example, Notepad is under stress and gives ‘Not Responded’ error message if 5GB data is copied from the website and pasted in notepad.
Need of Stress Testing :
- To evaluate the system behavior under abnormal or heavy conditions.
- Showing appropriate error message when the system or application is under stress.
- To analyze the behavior of the system after failure.
- To recover the system after failure.
- System failure could result in enormous revenue loss under various abnormal conditions.
- To verify if unexpected failures do not cause security issues.
- To ensure that data is saved before the system’s crash.
Stress Testing Tools :
- Neo load
- Site Blaster
- Database Benchmark
- Stress Tester
Advantages of Stress Testing :
- It helps to find the deadlocks in the software system.
- This testing ensure the system’s performance under load and stress conditions.
- To find application bugs that surface under abnormal conditions.
- This testing make sure that security vulnerabilities are not disclosed by load and stressful conditions.
- Software crash-proof software system are made by using this testing.
- This testing can provide the data that is hard to find anywhere.
Disadvantages of Stress Testing :
- This testing can not all possible scenario of testing.
- It only measures the overall response of the system to various stress scenarios rather than measuring and monitoring it.
- It contains limited scope and sensitivity.
- Stress testing can be time-consuming.
