As a developer, you understand the importance of conducting various types of performance tests to ensure that each feature or code added to the system does not negatively affect or break the system and that it functions effectively. However, the question that lingers in the minds of most developers is the type of load tests they should perform and the most suitable test for their situation or organization. You can read more on capacity, stress and load testing in this article.
Performance testing entails general tests that aim at checking on the performance and behavior of the system. It looks at the scalability, reliability, responsiveness, speed, and stability of the software and infrastructure in the business. Different types of performance tests provide IT experts with various data. Before starting a performance test in any organization, it is necessary first to define the system objectives so that you can tell if the system behaves as required or not depending on the needs of your customers. After carrying out a performance test on your system, you can then look at various KPIs including hits per speed, response time, number of virtual users, bytes per second, and errors per second as well as how they relate with each other. After the reports, you can then identify bugs, bottlenecks, and errors and come up with the appropriate solution. You can use performance testing when you want to analyze the performance of your site as well as app performance.
Load testing analyzes the functionality of systems under a massive number of synchronized virtual users. Also, the users should be performing transactions over a given duration of time, which also means that the systems deal with massive volumes of loads. A business can choose from an array of load testing tools available in the market today such as open-source tools, depending on its needs. Load testing is used when a business wants to determine the number of users that its system can handle. The test allows you to define various user scenarios that will enable you to focus on multiple system parts such as the web load testing or checkout site page on your site. Additionally, the test allows you to check on the behavior of load such as how it builds and sustains itself in the system. In fact, every business should carry out load testing often to make sure that the systems are on point all the time.
Stress testing checks your system’s upper limits by testing it under extreme loads. The testing analyzes the behavior of systems under extreme loads and how it manages to get back to normal usage. Stress testing also tests security issues, memory leaks, data corruption, and slowness. App and website stress tests are vital before significant events such as selling tickets for a famous concert or before elections. However, it is recommendable to carry out stress tests often to ensure that your system can endure all types of capabilities. It ensures that you prepare for unexpected traffic spikes so that you have enough time to fix bottlenecks.
These types of performance tests make sure that the organization knows about system problems so that it can plan. Also, companies should have experts to carry out the tests once in a while. Additionally, choose the right tool for your business.
