What is Schema?

Before we get into the topic "how to validate schema in rest assured", we need to go to some concepts. A schema is a database that contains structured information. It's used to describe your site's database structure in simple plain text, and it's often confused with Views or Controller actions because they are both important parts of any app. However, schema is relevant only if you want to define rules for your system's behavior; for example, if you have an endpoint where users can post content on your site (like [this](https://api.example.com/users), then this endpoint should return an array of objects representing all user data stored in the database (as opposed to just returning all posts stored under /users).

Schema defines the resources those files are associated with, so they can be located easily. A schema is a database that contains structured information, maps, and other static files. It also provides a way to describe your site's database structure in simple plain text. Schema is often confused with Views or Controller actions. Schema is relevant only if you want to define rules for your system's behavior.

JSON Schema

It is a syntax for describing the structure of JSON data. It's used to validate data in the browser, as well as other places such as server-side applications and mobile apps. JSON Schema is an open standard, released under the Creative Commons Attribution 3 license. This means that anyone can use it, modify it or even fork it if they have reason to do so (for example: if you want something more robust than what we offer).

What is Rest Assured?

It is an open-source Java-based library used by a team of designers to simulate and test the behavior of real-world XML and JSON-based web services. The APIs we test are in the cloud, not on a dedicated server. We use a combination of open-source and commercial tools to run these tests against large numbers of instances simultaneously, giving our clients confidence that they're making decisions based on reliable data. 

The REST Assured API allows you to create and manage your tests, as well as view the results of those tests in the IDE you already use. You can see the results of your test run right in your favorite IDE! Simply click "Test Run" and it will display all of its output while running on your machine or device (if applicable). Unlike traditional methods where you need to manually log into a server or wait until it finishes loading before seeing any results at all—you'll get instant feedback from any web application using this service. We also recommend using the different S-grade testing services provided by WeTest which include Remote Testing, Compatibility testing, Automated Testing, performance testing, and Security testing. These testing services feature multidimensional metrics and real-time analysis for extreme insights.

How to Validate Schema in Rest Assured?

One can easily validate JSON schema within the Rest Assured which makes sure that the response from this suite is according to the pre-built set of rules in a format according to the JSON body. To do this, one had to add the JSON Schema Validator dependency parameter in the project file being processed. To start the process, first, send a GET request via Postman on an endpoint and then check its response.

Developers usually provide a scheme of JSON response however it can also be generated from online resources like liquid technologies. (Search liquid technologies online JSON to schema converter). Launch the application and you will get a sample in which a JSON body can be added which needs to validate. When done, click the "Generate Schema" option. When generated, create a new JSON file and add the generated content in the file within the project and check the output.
