API load testing does not simulate real users interacting with elements of your webpage.However there are some limitations of API load testing: Load test will help to understand where and when your system breaks, fix the problems and avoid getting users unsatisfied and revenue loss.ĪPI load testing is one of the most important parts of testing and all teams should add to their testing Process. But, when number of users running the tests from worldwide above KPIs might not be same as earlier. Response time, error rate, memory leakage, and CPU might be top-level when you are running functional tests.
When testing your website, app or API endpoint under a load, you are actually simulating how it will perform when there is multiple users visit it, in real scenarios as your system can perform totally differently for one user compared to too many concurrent users due to the system’s resources.APIs allow you to send requests to your server while bypassing the UI layer. API load testing can be a great way to simulate users at a low cost.There are different ways that can be done load tests, but API load testing is one of the easiest methods at a low cost as it’s simple to script and there are many open-source tools for beginners which can be used very easily.ĪPI load testing has a lot of benefits when utilized in the proper context. API load testing is going through this process by simulating multiple users sending requests to the server at the same time. It’s a way to check whether the application can handle the load that is needed to handle with the potential customers. Load testing is simulating load that is expected to see in production to your application servers in order to determine how the application behaves before it goes live. So that will be useful to identify heavy load before they reach Production environments and make sure that the API is able to scale to multiple concurrent tests. So it is very important of simulating multiple users sending requests to the server at the same time in Development/QA environments. It is difficult to identify these heavy load because there is no such a production load in development environments. Load testing is a great way to help mitigating performance risks, because it ensures an API can handle an expected load. The importance of API Load Testing besides functional tests of the API?
