Stress Load Test

Load testing or a stress load test will test the demand a system or device has on it. It will then determine its response. A good example of a stress load test is in the construction industry. Cranes are required to carry and lift heavy loads above the ground. Large cranes for high rises can be dangerous if they cannot hold up to certain stressors. Therefore, in a stress load test of a crane the actual amount of a load the crane can lift without becoming dangerous needs to be obtained. This measurement can then tell the operator its limit.

Another way you can use a stress load test is with software. In this case it would be a software performance test, reliability test, or volume test on the software. It would test the limits of how much you can over load the software program before it will crash. We will look at both types of stress load test options.

First in mechanical load testing the system has to be verified according to certain regulations such as lifting operations or lifting equipment regulations as set up by the country. A country may have different regulations. In other words the UK may have slightly different regulations than the US. Load testing is done at the factory before a product is shipped. It will also have to be carried out again to recertify the equipment. As you are aware use can cause undue stress on a mechanical piece of equipment.

This is why the testing of mechanical equipment must occur more than once. As the equipment ages a new stress load test is required. It may even call for the equipment to be put aside for new.

A stress load test on software will examine the expected requirements of the program. Does the software load? If you have multiple users, will it crash? Many other questions should be asked. A good example of a stress load test for software is servers. A server has to be able to handle the visitors it receives and multiple web users hosting their websites on the same one. The load test will show if that is possible.
