Load Testing and What It Is

Load Testing is measuring the response of a computer or software to determine how the system will act under normal and anticipated peak load conditions. This test identifies the maximum capacity it can operate normally under, as well as any elements that causes slow, bottlenecking loading. Load testing helps servers form mechanisms in case of overloading of visitors and how any crashes can be saved in the event of a software’s malfunction under higher than normal conditions. There are various forms of load testing that covers all corner of the system being checked.

Load testing is simulation. It plays out what to expect before being released publically and to fix any glitches. What the maximum load is will never be identified until some test is done to see where the “stress level” is for that software. An extreme form of load testing is stress testing, which measures the system’s handling at peak mode, as well as going over its limits. Load testing identifies anything that may go bad when multiple users suddenly get on the system with a sudden surge of traffic. These things can be overlooked, even when code is checked repeatedly.

Load testing, however, can’t be performed until the project is close to completion, when user usage and performance can be accurately replicated. This is because a nearly finished system can work with thousands of users at once, making it more realistic. However, testing can be done even with no users because they are not the only reason for any overload. Sometimes, overload comes from having large files, heavy calculations, or low network connection.

The major purpose of load testing is to mitigate risk; risk to your software’s functionality, risk to the sanity of users and how they handle a page’s issues, and risk to the company. There is a psychological angle to load testing as it also tests a user’s actions, as well as the owner’s actions when there is a problem with the system. This is a human stress test on the computer stress test. What companies will learn is that they must focus on only the most important factors that lead to successful accessibility for customers and make sure that is problem-free.

A load test enables you to measure response times, throughput rates, and resource-utilization levels, and to identify your application’s breaking point, assuming that the breaking point occurs below the peak load condition.” – From Microsoft’s Performance Testing Guidance for Web Applications

There are multiple tools that can be used in load testing, such as Apache jMeter, WebLOAD, and Load Impact. These among a dozen other testing tools make it easy to create a demo of input/output of a website and their performance with them. They are affordable and sometimes free to download, based on the system it is meant to work with. This is all out there for people to test their websites and make sure nothing goes wrong when visitors arrive on the site. It is all for a successful business utilizing the power of the Internet and global connections.
