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.

Writing Basic Karate Tests

Now that we have completed the system preparation and IDE setup in the last chapter, we can directly dive into the main topic: writing Karate API tests.

Apart from the basic Karate commands and structure, we will also take a closer look at how to make test scenarios easier to read and more straightforward. When you have dozens or hundreds of scenarios, it is especially beneficial to make them as readable and understandable as possible, so you don’t have to think too much about what a scenario does and how the data looks.

In this chapter, we will cover these main topics:

  • Exploring the API under test
  • Calling endpoints and setting parameters
  • Matching status codes and responses
  • Making requests with payloads
  • Using variables and data tables
