Stress testing is a simulation technique used in multiple industries to determine their reactions to different unexpected situations. In software testing, you can benefit from stress testing by showing how the application behaves under extreme load conditions.
Shortly, stress testing is used to find the limit, at which the system or software or hardware breaks, by testing with overwhelming data or resources.
Stress tests are usually cloud simulation models that test hypothetical scenarios, also highly customised stress testing methodology is also often utilised.
Use stress tests to test the stability & reliability of your system and infrastructure. These tests determines the robustness and error handling under extremely heavy load conditions.
Main goal of stress testing
To reveal application bugs that can appear only under high load conditions. These issues can include race condition issues, memory leaks, and others.
Stress testing allows you to simulate and identify the application’s weak points. For stress testing to be successful, the application should display appropriate error message while it is under extreme conditions.
Example of stress tests
You can have a web server, that can be stress tested using various scripts, scripts, requests, bots, and various denial of service tools in order to have a better understanding of the performance of a web site during peak loads.It monitors system resources such as CPU, memory, I/O etc., and checks the ability of the application to recover back to normal when the workload is reduced.
