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.

Summary

In this chapter, we explored an area of Karate that deviates from its core API testing functionality. Even though API calls are used in the background, browser tests feel very different in that they focus on the UI of a web application.

First, we saw what browser tests are used for, why they matter, and that there are a lot of competing tools in this area between which Karate stands out due to its API focus. Specifically, we looked at how to write basic tests in Chrome and why this should be the first browser to start with.

Following this, we learned how to find and interact with web elements and saw what possibilities there are to speed up test development using Karate’s debugging functions.

Finally, we combined Karate’s mocking abilities with API call interception to bring this topic full circle.

In Chapter 10, Performance Testing with Karate Gatling, we will look at the last specialty of Karate: running performance and load tests against APIs to...
