Basic Purposes of Load Testing

If the software is at the final stage of its life cycle and already has passed almost all the main stages of its verification, the time for load testing comes. Many have heard this term, but not everybody knows what it means.

So, the load testing is aimed at confirming that the system, being under continuous and steadily increasing stress, retains its performance. Such testing is carried out until the program reaches its threshold limit. Sometimes testers prefer to complement the load process with automation components, as it helps to simulate conglomerations of processes from a large number of simultaneous users. Often this technique is also called a subspecies of stress testing as a mutual goal of both these kinds is the endurance testing.

Most of those who belong to the software testing environment have quite a contradictory opinions regarding to the use of load testing. Let's start with the fact that this method Rich Mom Review does not apply to functional testing. In fact, it is an attempt to exactly reproduce the process of alleged disposal of a product by the majority of users who at one and the same time perform some processes causing the increase of a load on software.

Through such testing, testers may variate the types of loads on software - it is necessary for defining the full range of the program's endurance and for identification of the weakest points of a product, affecting its quality.

3 Types of Load Applied During the Load Testing Process:

1. Overload - the maximum possible load on the software, which is supposed considering the potential user audience.

2. Normal load - most optimal number of simultaneous processes and users, which, as the developers expect, will occur the most frequently and is considered as a normal condition for the system.

3. Zero-load - sometimes testers apply "empty" tests to check how the system will react to the complete lack of load.

Now let's look at the basic purposes of the load testing. This type of testing is often applied to the performance testing, volume testing and reliability testing, so, as well as for these three types of testing, for the load testing it is necessary to observe the behavior of the product, namely the non-functional properties, such as scalability, maintainability, extensibility and scalability.
