Stress Testing in Software Engineering

Stress Testing

  • 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 : 

  • LoadRunner
  • Jmeter
  • Neo load
  • Site Blaster
  • Database Benchmark
  • Tsung
  • Stress Tester
  • Locust

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.
