Request URL – The URL is the link that the API communicates with.

Many testers use Postman for its quick workflow that allows the set-up of all the headers and cookies that the API expects, while checking for the response.
#LOAD TESTING WITH POSTMAN HOW TO#
WebUI Testing – Validates GUI items in the context of end-to-end integration.īelow, we see how to perform API testing using Postman.Runtime Error Testing – Looks for errors detected during the execution of the system.Security Testing – Tests what kind of authentication is required to access the API.Load Testing or Performance Testing – Tests the performance of the system under high load.
#LOAD TESTING WITH POSTMAN CODE#
Unit Testing – Tests the functionality of an individual part of the system whether the code is doing the right thing.Functional testing – Tests the functionality in the system whether the code is doing the right thing.The following are different types of API testing: Hence, in most modern systems, we need independent API testing to validate our interconnected applications to determine if they meet expectations for functionality, accuracy, performance, reliability and security. The app actually calls the Google Maps or Esri API and waits for a response to provide the information. For instance, when you book a ride with Uber or Lyft, the app itself doesn’t know how to calculate the route to the destination. The critical link is the waiter who delivers your food to the table, playing the role of the API in interacting with the system. An analogy is a waiter who interfaces with a restaurant’s kitchen, which is the system that prepares your order. An Application Programming Interface (API) is a construct in which one can send a request and tells a system what you want to do (usually after appropriate permissions are checked), the system returns a response back to you. It allows users and testers of APIs to send HTTP requests and read their responses. Postman is one of the popular applications in the market used to create, test and document APIs. Postman, which started as a chrome browser plugin, is now a complete GUI-based application and is used by more than 100,000 companies worldwide.
