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.

Making your tests more concise

There are certain principles in software development, such as don’t repeat yourself (DRY) and keep it simple, stupid (KISS), that lead to better and more maintainable code. If your code adheres to the DRY principle, it means that there is not a lot of duplicated code, whereas KISS means that your code should be easy to follow and understand. Both principles can be tackled in Karate, making your tests more fun to work with in the process.

Reducing code by calling other feature files

Background scenarios solve code duplication inside a single feature file, as we saw before. However, it can be beneficial to define common functionality for multiple feature files in a central place.

Also, it is possible to split feature files into smaller reusable parts so that we don’t have very large scenarios that are hard to read and understand. In this section, we will cover both cases.

We will start with a feature file called sayhello.feature...
