Don’t Miss This Cypress API Testing Guide

This is the first article for Cypress API Testing Guide in this article, we will understand what is an API and if there is an option to use Cypress for API tests.

What Is An API?

An API (Application Programming Interface) is a set of definitions and protocols for building and integrating application software. API stands for an application programming interface.

APIs let your product or service communicate with other products and services without having to know how they’re implemented.

Examples Of API Requests

GET – Used to request data from a server

POST – Used to send data to a server

PUTUsed to send data to a server, create/update a resource

DELETE – Used to delete data on a server

API Components

URL – Also known as endpoint (HTTPS link)

Headers – Usually it’s Content-Type or Authorization token (Authentication information)

Type – Get, Post, Put, Delete

Body – JSON object with the requested data (sometimes called “body” or “message”)

Cypress API Testing

Cypress Ui tests perform “test action” via the browser, demonstrating real user actions and in the process, multiple API calls could be sent back and forth between the client and server.

This framework provides the ability to extract data from the server.
This data could even pump into the cypress test automation framework, eliminating the need to depend on fixed data sets.

Also has the ability to act as a middleman to intercept API calls.
We can also provide mocked responses for specific API’s eliminating the need to rely on the backend server, in the process increasing the speed of tests.

Summary

API – Application Programming Interface (Black Box)

Types of requests – Get, Post, Put, Delete

A typical request has: URL, Headers, Request type, Body

Cypress has a built-in server that can intercept browser API requests and provide a mock response.

Cypress can make API requests and process responses.

In the next article, we will talk about JSON Objects and how to test them with Cypress.
