Json schema validation using Rest assured. not able perform

Question

public class Response_SchemaValidation 
{
    public static void main(String [] args) throws FileNotFoundException
    {
        System.out.println("This is testing...");
        
        String str ="{\r\n" + 
                "    \"firstname\": \"Sally\",\r\n" + 
                "    \"lastname\": \"Brown\",\r\n" + 
                "    \"totalprice\": 111,\r\n" + 
                "    \"depositpaid\": true,\r\n" + 
                "    \"bookingdates\": {\r\n" + 
                "        \"checkin\": \"2013-02-23\",\r\n" + 
                "        \"checkout\": \"2014-10-23\"\r\n" + 
                "    },\r\n" + 
                "    \"additionalneeds\": \"Breakfast\"\r\n" + 
                "}";
        
        
        //InputStream insp = new FileInputStream("C:\\Users\\ANANDA K R\\eclipse-workspace\\API_Automation_petStore\\Schema_validation_jsonFiles\\Response_SchemaValidation.json");
        //File fl1= new File("C:\\Users\\ANANDA K R\\eclipse-workspace\\API_Automation_petStore\\Schema_validation_jsonFiles\\Response_SchemaValidation.json");
        RequestSpecification reqstBody = 
                RestAssured.given().body(str).header("Content-Type","application/json");
            Response resp = reqstBody.post("https://restful-booker.herokuapp.com/booking");
            //resp.js 
            
            System.out.println(resp.statusCode());
            String str2 = resp.getBody().asString();
            System.out.println("str2 ---"+str2);
            Assert.assertEquals(resp.getBody().asString(), matchesJsonSchemaInClasspath("Response_SchemaValidation.json"));
            
        
    }

}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: Schema to use cannot be null
    at io.restassured.module.jsv.JsonSchemaValidator.validateSchemaIsNotNull(JsonSchemaValidator.java:270)
    at io.restassured.module.jsv.JsonSchemaValidator.access$300(JsonSchemaValidator.java:75)

    at basic_SchemaValidation.Response_SchemaValidation.main(Response_SchemaValidation.java:173)

    @Test

    String payload = "{\n" +

                given().
                contentType(ContentType.JSON).

                body(JsonSchemaValidator.matchesJsonSchemaInClasspath("ResponseSchema.json"));
    }

ResponseSchema.json

{

  "properties": {
    "bookingid": {
      "type": "integer"

          "required": [

Keep the schema file in src/test/resources. Generate schema online based on your response using this website:https://www.liquid-technologies.com/online-json-to-schema-converter. After that store schema(ResponseSchema.json) in class path and add Json Schema Validator dependency as well. Link:https://mvnrepository.com/artifact/io.rest-assured/json-schema-validator.

Thank you. for the code,, It is in BDD format.. But am looking for normal selenium format.. In normal selenium format this body is not taking any paramters. for validating json.

cyrilgeorge153 Over a year ago

Rest assured has got no connection with Selenium. Rest assured is a Java DSL for API testing. Selenium is for automating browsers. You are mixing these two in wrong manner. The above answer is correct. Just update the api end point and pass the payload in body. This code will work.

I have updated the answer with correct payload and endpoint also checked from my side. It is working. I cannot help you more. This is the correct way of doing schema validation in rest assured.

Thank you, i too tried the same ,, it is working..
