Second, we keep the load unchanged for 10 minutes.įinally, we reduce the load gradually to 0. In the example below, we test a system for 12 minutes.įirst, we give 1 minute to grow the number of VUs from 0 to 10. It is not resource-intensive and doesn’t need much memory or advanced hardware. spacecraft-astronau2 20 April 2022 19:45 1 Hello I want to do stress test to my API, and as the title said i want to choose my tool to do it, and i would like to know the opinion of the postman community. When testing anything “User journey” related, web apps, websites, or API endpoints in a specific order, you should think in terms of Virtual Users.Ī Baseline test is the simplest one launched locally at the desktop to check the changes in a system’s behavior.They run concurrently and keep repeating the test until the test is over.An entity that executes a test and makes requests.For the stress test, you may have an x10 figure of VUs to check the capability of your app to serve them. They will be different for the regular hours and rush hours. It means we will need 27 VUs for the test.Īgain, the figures may change depending on the case. Let’s say that an app receives 10 000 users per hour, and an average session duration equals 10 seconds. To decide how many VUs you need in your situation, consider using the formula below: It will let you know whether your app can bear this or not. You may need to create VUs to check the load of the website and its performance in various circumstances, such as when you make changes to the website or when you get an unexpectedly huge volume of traffic. Going to a single website looks like just one request, but in reality, it is a long chain of requests to different components of the page. If we take a look at the simple test above, we can imagine that one VU goes to, downloads an HTML page, all sets, JavaScript, images, CSS, etc. Once the test is launched, VUs start making requests concurrently until the end of the testing procedure. It emulates the behavior of real users, which means when you launch your test, VUs will do everything as though they are the real visitors of your website. Virtual Users (VUs) is one of the key concepts here. In the end, you get the report to analyze and make decisions based on your satisfaction with them from both technical and business perspectives.Ī test can be as simple as this: // script.js You create users, parameters, and metrics and let your test go. Performance testing is thought of as a user behavior scenario. It looks much like a unit test but for performance measurement. It is remarkable for the easy-to-read output and stunningly-designed documentation. If you have basic experience with JavaScript, you can get the tool and implement it instantly. It has been created with a fierce commitment to contemporary DevOps ideas, and it supports HTTP requests. K6.io is a testing tool suitable for performance, load, and stress testing.
