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.

Let’s create a new Karate project by following the steps from Chapter 2 in the Setting up a Karate project with the Maven archetype section.

Since we will write our tests ourselves and don’t need additional configurations for now, we can delete the complete examples folder as well as the karate-config.js file. So now, your project should look like this, ready to be filled by us:

In the next step, we will create our first test case.

Adding a new feature file

Let’s add a new scenarios folder under src/test/java that our feature files will be in:
