API Performance Testing using Postman Tool

EasyChair Preprint 12877, version 2

Abstract

Postman is an API platform for building, using and testing APIs. Postman aims to simplify each step of the API lifecycle and streamlines collaboration so you can create better APIs. This article provides an introduction to the different features of Postman as a test automation tool for software performance testing.

Postman is an API platform for building and testing Application Programming Interfaces [API]. Postman streamlines the stages in the API lifecycle and promotes collaboration to generate APIs, better and faster. Performance testing is a type of testing in which the speed, responsiveness, and stability of a software, product, or network is evaluated under peak workload. Performance testing checks and validates an application’s capacity and ensures that it works well within the acceptable Service Level Agreements.

The performance testing feature in Postman is designed to test the API endpoints under varying loads and to assess how well the APIs handle different loads. Accordingly, potential performance bottlenecks in API can be identified and performance-tuning recommendations can be provided by the performance team. It helps to optimize and enhance the overall API performance.

To sum up, the performance testing capability introduced in the Postman is a valuable feature that enhances the overall scalability feature of API. It provides option to reuse existing API collections for performance testing with minimal effort. From a testing tool standpoint, there is still scope for improvement in terms of features and capabilities.
