7 karate framework json array validation

karate is a powerful open-source framework for api testing that allows you to write tests in a readable and expressive format. one of the key features of karate is its ability to validate json responses easily, including array validations. in this tutorial, i'll provide you with an overview of how to validate json arrays in karate along with code examples.

getting started with karate

basic structure of a karate test

a typical karate test file has a `.feature` extension and follows the gherkin syntax. below is a basic structure:

json array validation

now, let’s focus on validating json arrays. assuming you have a json response like this:

step 1: validate array size

to validate the size of the json array, you can use the `size` method:

step 2: validate array contents

you can validate the contents of the json array, including specific fields. to check that the first user has the expected properties, you can use:

step 3: validate all elements in array

you can use the `contains` keyword to validate that the array contains specific values or objects. for instance, to check that the array contains a user with a specific name:

step 4: validate array using custom logic

you can also validate the array with more complex logic, such as ensuring that all users are above a certain age. here's an example using a loop:

running the test

to run your karate tests, you can use maven with the following command:

conclusion

in this tutorial, we covered how to validate json arrays using the karate framework. we explored validating the size of an array, checking specific values, ensuring certain elements exist, and applying custom logic for validation. karate's expressive syntax makes it straightforward to perform these validations, allowing you to ...
