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.

Using data tables

Data tables are a way to define data for steps in a tabular way, which makes it clearer when dealing with complex JSON arrays.

Here is a basic example:

* table numbersAndWords
   | number | word   |
   | 5      | 'five' |
   | 10     | 'ten'  |
* print numbersAndWords

This prints out the following structure:

13:31:39.879 [com.intuit.karate.cli.Main.main()] INFO  com.intuit.karate - [print] [
  {
    "number": 5,
    "word": "five"
  },
  {
    "number": 10,
    "word": "ten"
  }
]

This is how the data table is turned into JSON:

  • The * table numbersAndWords line signals to Karate that a data table is expected that...
