#LOAD TESTING WITH POSTMAN SERIAL#
Each virtual user executes the selected sequence of requests in the collection in serial order as represented on the Collection Runner. Virtual users are the parallel users that will hit your APIs at the same time. How virtual users help you simulate load on your API workflows Once reached, this number of virtual users will be maintained for the remaining duration: “Ramp up” load profile: This will slowly increase the number of virtual users during the “ramp up duration” to reach the specified load. “Fixed” load profile: This will apply a fixed number of virtual users throughout the test duration: Load profile: The intensity of the load during the test’s duration. Test duration: The amount of time (in minutes) for which you want to run the test. Virtual users (VUs): The maximum number of parallel users you want to simulate. You will be able to specify the following inputs to simulate the load condition: You can now use the Collection Runner to simulate real-world traffic.

Step 4: Once the run is completed, observe and identify bottlenecks in response times and requests per second: How to configure the load to simulate real-world traffic You can toggle on the legend to view requests per second as well. Step 3: Observe the response times and error rate in real time: Step 2: Select the Performance tab under Runner, specify the load settings, and click Run: Please note that Postman will also execute all of your pre-request and test scripts along with the requests. If you do not have a collection, read more about how you can quickly create one in Postman. Step 1: Select a collection, select an environment (optional), and click Run: You can use Postman’s Collection Runner to set up a performance test in Postman by following these steps: How to use Postman for API performance testing We will show you how to observe response times, throughput (requests hit per second), and error rates so you can keep tabs on your API performance metrics. Visualizing the performance of your APIs under the simulated load in real time. Using Postman to simulate load by having multiple parallel virtual users hit your endpoints. There are two core functionalities we will discuss in this post: Postman now has built-in capabilities for testing your API’s performance with your existing Postman Collections and requests. Introducing API performance testing in Postman from your machine Identify any bottlenecks, latency, and failures and determine the scalability of the system. Optimize and improve the API’s performance to ensure a better user experience. It is conducted to evaluate how well an API meets performance expectations for response time, throughput, and availability under the simulated load.Įnsure your API can handle the expected load and check how the API responds to changes in load (load is the number of parallel users hitting your APIs at the same time). To ensure user success, you need to know that your APIs meet the expected functionality (through functional testing) and also that they can handle the expected traffic volume (through performance testing).ĪPI performance testing involves simulating real-world traffic and observing your API’s resulting behavior. APIs have increasingly become the backbone of such modern businesses, and the quality and reliability of these APIs impact how customers experience a product. In today’s fast-paced digital world, providing a great user experience is essential to building a sustainable business and staying ahead of competitors.
#LOAD TESTING WITH POSTMAN UPDATE#
Today, we are excited to announce the general availability of this game-changing update to the Postman API Platform. To address the above concerns, we recently launched early access to Postman’s exciting new API performance testing feature. If so, you’ve likely realized that as you scale, your API’s performance impacts the success of your products and business. How can I identify performance bottlenecks that may become major production issues? Will my users see acceptable response times when my system is under load, or will they see errors? How will the response times change when multiple users are sending requests at the same time? How will my APIs perform in real-world situations?
When it comes to API testing, you may have wondered some or all of these questions:
