Load testing can be defined as the process of putting a demand (load) in your application to measure its response. This process helps you identify the maximum capacity of your application or infrastructure and it can highlight bottlenecks or problematic elements of your application or infrastructure. The normal way of doing load testing is first doing a test on "normal" conditions, that is, with a normal load in your application. Having measured the response of your system under normal conditions allows you to have a baseline that you will use to compare with in future testings.
Let’s see some of the most common tools you can use for your load testing. Some are simple and easy to use and others are more complex and powerful.
