JSON validation using REST assured

Question

i'm trying to validate Json Objects. I use https://code.google.com/p/rest-assured/wiki/Downloads?tm=2,

import static com.jayway.restassured.module.jsv.JsonSchemaValidator.matchesJsonSchemaInClasspath;
import static org.hamcrest.MatcherAssert.assertThat;

import org.junit.Test;

public class testClass {


    @Test public void
    validates_schema_in_classpath() {
        // Given
        String JsonString = "{\"isSuccess\":false}";// Greeting response

        // Then
        assertThat(JsonString, matchesJsonSchemaInClasspath("greeter-schema.json"));
    }
}

greeter-schema.json:http://cs606926.vk.me/v606926718/15603/0Kauo1bTDi8.jpg

I have OK result everytime even if JsonString is not equal this "{\"isSuccess\":false}".

For example I get OK result when JsonString="{\"isSuccess\":false},{\"isFalse\":true}", or "{\"isSuccess\":false},testetstets"

word of advice: paste the schema as code in the question instead of linking to external resource — soulcheck
I have no reputation to do this - schema contains a lot of urls — user3510509

Schema validation using RestAssured only asserts that the value is there. To assert against a certain value, you have to denote exactly what name (isSuccess in this case) you are looking for to get the value. Then validate against this derived value:

assertThat().body("isSuccess", equalTo(false));

This functionality is actually what RestAssured was built to do, and there is plenty of info on it here: https://github.com/jayway/rest-assured/wiki/Usage#json-using-jsonpath
