Load testing is an important way of ensuring the performance and reliability of web applications under various levels of stress. Postman, a popular API testing tool, offers capabilities for conducting basic load testing to simulate multiple users accessing an API concurrently. In this article, we'll explore how to perform basic load testing with Postman to assess the performance of your APIs.

What is Load Testing?

Postman load testing is a method of testing the performance and scalability of an API (Application Programming Interface). Load testing involves simulating multiple users or clients accessing the API simultaneously to see how it performs under different levels of load.
