Stress Testing Meaning and How it is Performed

Stress testing in technology is the deliberate intense testing of a computer’s hardware or software performance to evaluate the impact of adverse and extreme or unfavorable conditions on its performance and determine the stability of the system under such abnormal operational capacities. Being that most systems are build with the assumption of normal operational conditions, stress testing is conducted thoroughly with an intensity that overrides normal operations which may lead a system to its breaking point just to observe the behavior of the system under such intense conditions. The objectives of stress testing include:

  • To ensure a system’s intended performances are met.
  • To determine stability of operations of a part or a system beyond
    normal operational standard usage
  • To determine the user limits of a system and obtain its breaking

How stress testing is performed

Stress testing is mostly performed by reliability engineers who conduct the tests under expected stress conditions as well as extreme stress conditions to prepare users on the operating life of a hardware or software and to record the causes of hardware or software failure for future reference. The process of stress testing can be performed as quantitative tests conducted in the lab like measurement of frequency of system crashes or frequency of errors during the testing process.

Stress testing in software is performed through breaking transactions of software by loading concurrent users beyond normal levels to determine the system’s weakest link even where the database does not have any load. This determines the ability of the software to handle errors that might occur under extremely heavy traffic loads to prevent it from crashing due to insufficient
resources. In CPU, stress testing is performed by establishing heavy system loads and testing for any hangs or crashes on theCPU to determine whether the CPU can withstand the heavy loads.

Hardware stress testing is performed by establishing abnormal environmental changes to ensure the stability of the hardware under adverse conditions. Website stress testing is performed through establishing abnormally heavy traffic or abnormal data to determine any limitations to any of the website functionalities.

What Is Load Testing?

Load testing is one of the critical processes as far as testing the quality of software or computer system; load testing is done to measure the speed of both to determine the behavior of the system under the normal, peak load conditions and the downtime. Load testing is essential since it helps to ascertain the capacity of an application, their weaknesses and determine the elements that cause them and ensuring that necessary improvements are made before launching the application. Stress testing involves testing the ability of a request to withstand loads that are higher than the usual. It would be important to note that the burden is usually so high that those errors are the expected results. Testing a software helps to determine its performance, reliability and the capacity; it is used to validate the suitability of the software for a given use.

What is software load testing?

Load testing varies with different software; this is because there are different uses of software. However, load testing is an important process in determining the ability of software to perform a given function especially if the system where the software would be put in use is multi-user and would be the server of many software. Other types of software such as the word are tested by forcing them to read large documents; it would be critical to know that when doing software testing, use the actual use rather than using theoretical or analytical models. In addition to software, servers can also be load tested. Whether you’re trying to find out what the fastest loading web hosting companies are, or you’re trying to run a website speed test, There are a variety of ways that you can test web servers.

What is load testing in websites?

When doing load testing for your site, it would be important to use the actual performance behavior. One of the conventional ways of doing load testing is recording the performance of the site when the customers visit; a script recorder is harnessed to register the communication and then record the interaction scripts that would be used to simulate the process. Once load testing is complete, a load generator would be used to replay the performance of the site when in use. The load generator could be modified to be used to test different parameters. It would also be important to check the hardware and software specifications of the system so as to determine the areas that need to be improved.
