Writing API Tests with Karate

By: Benjamin Bischoff

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.

What this book covers

Chapter 1, Introducing Karate’s Core Concepts, introduces the Karate testing framework, which provides an overview of its strengths, key concepts, and special features.

Chapter 2, Setting Up Your Karate Project, provides a step-by-step guide for setting up a new Karate test project, including integrated development environment (IDE) preparation, dependency management with Maven, and basic configuration using the Karate configuration file.

Chapter 3, Writing Basic Karate Tests, introduces writing the first API tests using Karate, which examine return codes and responses while ensuring code efficiency through Karate and Gherkin mechanisms.

Chapter 4, Running Karate Tests, explores various methods for triggering and running Karate tests, including considerations for running tests in CI/CD pipelines, selecting test cases, and executing tests in parallel to optimize runtime.

Chapter 5, Reporting and Logging, gives an overview of Karate’s built-in reporting and logging capabilities for effective troubleshooting, plus a guide for integrating third-party reporting solutions.

Chapter 6, More Advanced Karate Features, explores concepts and techniques for creating more complex test cases, including setting and checking headers, cookies, and authentication tokens, testing GraphQL APIs, and switching between different test environments.

Chapter 7, Customizing and Optimizing Karate Tests, shows how to create custom functionality in Karate through JavaScript functions and Java interoperability, as well as how to write custom Karate hooks to react to Karate events.

Chapter 8, Karate in Docker and CI/CD Pipelines, integrates Karate tests into CI/CD pipelines to establish a fully automated test setup using the example of GitHub workflows.

Chapter 9, Karate UI for Browser Testing, introduces Karate UI, a special module for browser-based test automation, and explores how this alternative approach to user interface (UI) testing fits into the Karate ecosystem.

Chapter 10, Performance Testing with Karate Gatling, explores the integration between Karate and the popular Gatling framework for load and performance testing, which reuses existing Karate scenarios.
