What is Stress Testing?

• It is a part of non-functional testing.

• It comes under performance testing.

• This testing verify the stability & reliability of the system.

• It is done to ensure that the system would not crash under heavy load condition.

• Basically, the use of stress testing is to determine the maximum load, at which the system breaks.

• This testing display the defect related message when the system feel stress or out of handle capacity.

• The recovery of the system is very critical after heavy stress.

• To verify that the system has saved the data before crashed.

• To verify the unpredicted bugs are not a reason of security issues.

• It help to verify internal progressions and controls.

• It help to find out the infringement(break) point and focus on the solution to avoid such conditions.

• It help to verify the compatibilty, performance, load etc. and prevent the system to crash.

• This testing helps to verify that the system behave as expected with both underload and beyond limit.

Tools for Stress Testing:

1. Load Runner

2. JMeter

3. WebLoad

Disadvantages of Stress Testing:

1. Stress testing can be time-consuming.

2. System can be slow if test the system stability for long time.
