Validate Response Status

How To Validate Response Status Using REST Assured ?

REST APIs have Status which is consist of three parts represented as a string known as Status Line.In this string the first part represents HTTP protocol version,second one represents Status Code and the third one reperesents the string value of status code.

To fetch this status line Rest Assured provides an interface 'Response' that have many methods,of which we will use methods getStatusLine() and getStatusCode() for accessing its status :

io.restassured.response.Response response= httpRequest.get("/Books");

response.getStatusLine()

response.getStatusCode()

Furthermore,we will apply assertions on them to validate/verify the results :

import org.testng.Assert;

Assert.assertEquals(response.getStatusLine(), "HTTP/1.1 200 OK", "Incorrect Status Line Returned");

Assert.assertEquals(response.getStatusCode(), 200, "Incorrect Status Code Returned");

Let's take an example -

Validating Response Status Code and Status Line :

package apiTesting;

import org.testng.Assert;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import io.restassured.RestAssured;
import io.restassured.specification.RequestSpecification;

public class ValidateResponseStatus {
   RequestSpecification httpRequest;
   io.restassured.response.Response response;

    @Test
   public void validateResponseStatusCode() {

        // Validate Status Code
       Assert.assertEquals(response.getStatusCode(), 200, "Incorrect Status Code Returned");
   }

    @Test
   public void validateResponseStatusLine() {

        // Validate Status Line
       Assert.assertEquals(response.getStatusLine(), "HTTP/1.1 200 ", "Incorrect Status Line Returned");
   }

    @BeforeClass
   public void apiSetUP() {
       RestAssured.baseURI = "http://localhost:8080/msg/webapi";
       httpRequest = RestAssured.given();
       response = httpRequest.get("/userProfiles");
   }

}
 

Output :

[RemoteTestNG] detected TestNG version 6.14.3
[TestNGContentHandler] [WARN] It is strongly recommended to add "<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >" at the top of your file, otherwise TestNG may fail or not work as expected.

Change "HTTP/1.1 200 or "200" with some other values and try to run the test,you will see error messges as assertions would be getting failed.
