Writing API Tests with Karate

Introducing Karate’s Core Concepts

The software testing world is constantly changing. Technologies that were recently state of the art are replaced or turn out to be slow sellers. New frameworks are created all the time to try to solve common testing problems. There are a lot of people who have entrenched opinions about how tests should look, and sometimes this attitude can even block progress. Testing is often still divided into exploratory testing (also called manual testing, which I personally dislike) and code-heavy automation solutions (also known as test automation), which may require a software expert for development and maintenance but might not be feasible for more hands-on exploratory testing.

In between these extremes, there is plenty of room for innovation. There has been quite some progress here during the last few years, and these new technological solutions are in high demand.

The Karate framework is a rather new contender in the software testing field that has set out to solve many of the problems raised, especially the steep learning curve of other solutions.

We are going to cover the following topics:

  • What makes Karate stand out?
  • Behavior-driven development (BDD) versus Karate
  • Supported data types in Karate
  • The JavaScript engine
  • Java interoperability

Technical requirements

All code examples for this chapter can be found on GitHub at https://github.com/PacktPublishing/Writing-API-Tests-with-Karate.

Demo code

It is not necessary to set up the programming environment at this point. All code that is shown here is just to demonstrate Karate’s inner workings and core functionality. In the next chapter, we will deal with this thoroughly!

Description

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.

Who is this book for?

This book is for QA engineers and developers who are familiar with APIs and want to make them safer and more secure by applying automated tests with the help of a lightweight and modern framework - Karate.

I learned a lot about the Karate framework, a powerful tool for API testing automation, from reading this gem by Benjamin Bischoff. The book is a clear and practical guide that covers the basics and the advanced features of Karate, such as UI browser testing. It also focuses on the aspects of security and performance, which are important for developing robust, secure, and high-performing applications. The book has plenty of code snippets and examples that help me understand and apply Karate in various scenarios. It is an excellent resource that teaches me how to conduct comprehensive API testing using Karate. I recommend this book to anyone who works with or wants to learn more about API testing. It will help you write robust, secure, and high-performing API tests using Karate.One of the things that I like about the book is its structure. The flow of explanation is smooth and consistent, without breaking or jumping to another theme. The book is well-organized into chapters that cover different topics and aspects of Karate. Each chapter has a clear introduction, a summary, and a list of key points. The book also has a glossary, an index, and a list of references for further reading. The structure of the book makes it easy to follow and learn from, but also allows me to start reading from any chapter and easily understand it. The book is designed to suit different levels of readers, from beginners to experts.

When I read Peter Thomas' foreword in this book, I felt nostalgic. I started my journey with Karate back in 2017 and coached many peers in writing Karate tests. Karate is a minimalistic test automation framework often referred to as a Swiss knife due to its versatility and ease of learning. At that time, I wished we had a book like this to help onboard aspiring Karate learners. This much-awaited book is essential for anyone interested in learning about Karate. Don't be misled by the title, "Writing API Tests with Karate." The author, Benjamin Bischoff, is dedicated to providing comprehensive and descriptive test examples, including API and end-to-end UI testing in this book. Additionally, the book covers mock and performance testing with Karate. If you have an e-book copy, you can click on the hyperlinks and access the GitHub repository to embark on your Karate learning journey immediately.

I am an SDET who is currently using RESTAssured for API Testing. Whenever I create a framework and test using REST Assured, I have felt that there are few parts missing. I was looking for option to switch and then I found Karate framework. Karate is the only open-source tool to combine API test-automation, mocks, performance testing and even UI automation into a single, unified framework.This book on ‘writing API tests using karate framework’ serves its purpose. The simple language and clear explanation of the flow makes it very interesting. I am very much impressed by the author’s effort to make this framework very understandable and usable. I would recommend this book to anyone who is planning to learn API testing or to someone who is looking for better framework to test APIs.
