Load testing is important so that you know exactly how much can your device handle. You will need to conduct this test so that you know what you can do with your device. You need to know that your system not only performs under normal conditions but how much stress can it handle or at what point it might crash or break down so that you are prepared to rectify immediately when the need arises.
You need your device not only do the normal things on a daily basis but also be good enough to handle a little stress when you need to do something bigger than the normal. For instance, your system shouldn't stop working if you need it to perform a bigger task than it usually performs daily. (for example: testing an API).
You shouldn't have to worry that your computer is not good enough to perform certain tasks and to find out and release yourself from the uncertainty you to need to do load testing to determine the strength of your device.
Load testing will help you find out how your computer works itself under stressful conditions. If it can take on stress and keep running or cannot handle stress and it breaks down or crashes when you are doing the load tests on it. No matter what the result you will be glad to conduct the load test to find out how good or bad your device is.
It is important to conduct such load and stress test because you would know exactly how your device will perform under given circumstances and at any particular given time. Also, how much load can you subject your device to when the need arises so that it functions without crashing or breaking down.
So you can know device’s limitations and manage your dependability on your device accordingly. This kind of testing lets you know if you have a device you can depend upon or not.
