I have a simple rest-assured test that is verifying this json comes be with the correct data for a call. I am using rest-assured 1.8 and did swap the groovy jars for the groovy-all jar due to a known issue with 2 different versions of ASM.

My json the comes back looks like this:

{"account":"12345"}

My code looks like this:

package com.blah.tests;

import org.junit.Test;
import static com.jayway.restassured.RestAssured.given;
import static org.hamcrest.Matchers.equalTo;

public class AccountsTest {

public AccountsTest() {
}


@Test
public void getLocationAccount() {

            given().
                param("thingAccountIsfor","ABCD").
            expect().
                statusCode(200).
                body("account",equalTo("10")).
            when().
                get("http://machine:2343/rest/accounts/getaccount");

    }

}

When I run this matching the value i expect for the account it works fine. When I put in a value that does not match I get a stack trace:

log4j:WARN No appenders could be found for logger (org.apache.http.impl.conn.SingleClientConnManager).
log4j:WARN Please initialize the log4j system properly.

java.lang.AssertionError: 1 expectation failed.
JSON path account doesn't match.
Expected: 10
  Actual: 12345

Process finished with exit code 255

I am running this inside Intellij. I did try to move the groovy jars, back in, move the conflicting version of the ASM off of my class path and re-run it. I got the same result so I don't beleive this has to do with using the groovy-all jar instead of the groovy jars that ship with rest-assured 1.8.

Does rest-assured throw an exception every time it has a test fail or is something wrong here?

Yes, it will fail by throwing AssertionException. You have two ways to avoid this:

  1. Catch the exception with AssertionError.

  2. Remove expect().statusCode().body() part and assign response to Response object and continue with desired tests by parsing it using JsonPath object as below.

    Response res = given().
    param("thingAccountIsfor","ABCD").       
    when().
    get("http://machine:2343/rest/accounts/getaccount");
JsonPath jp = new JsonPath(res.asString());
String account = jp.get("account").toString();
