Overview of this book

Software in recent years is moving away from centralized systems and monoliths to smaller, scalable components that communicate with each other through APIs. Testing these communication interfaces is becoming increasingly important to ensure the security, performance, and extensibility of the software. A powerful tool to achieve safe and robust applications is Karate, an easy-to-use, and powerful software testing framework. In this book, you’ll work with different modules of karate to get tailored solutions for modern test challenges. You’ll be exploring interface testing, UI testing as well as performance testing. By the end of this book, you’ll be able to use the Karate framework in your software development lifecycle to make your APIs and applications robust and trustworthy.

Working with headers and cookies

Headers and cookies are often used in web and API development to improve the user experience and functionality. Headers are pieces of information that are sent between the client and the server when a web page is requested. They can be used to specify the type of content that is being sent, the location of the content, and other details that can help the server process the request and send an appropriate response. Cookies, on the other hand, are small pieces of data that are stored on the client’s computer and can be used to remember information about the user and their preferences. This information can be used by the website to provide a more personalized experience for the user, such as remembering their login details or preferences for the site. In this section, we will work with both.

The code examples for this section can be found in the project repository under https://github.com/PacktPublishing/Writing-API-Tests-with-Karate/tree/main...
