POST Request

In this lesson, we will learn how to automate a POST request for different use cases.

We'll cover the following...

In this lesson, we will discuss two variations of the POST Request:

  1. POST with string body
  2. POST request using POJO (Plain Old Java Object) class

HTTP POST request automation

In this lesson, we will discuss two variations of POST Request.

Example 1 – POST with a string body

  • HTTP Method: POST
  • Target URL: http://ezifyautomationlabs.com:6565
  • Resource path: /educative-rest/students
  • Message body: As a String Object
  • Take a look at the code below:
Java


import static org.testng.Assert.assertTrue;



import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.testng.annotations.Test;



import io.restassured.RestAssured;

import io.restassured.response.Response;





public class POSTRequestTest {



	private static Logger LOG = LoggerFactory.getLogger(POSTRequestTest.class);

		

	@Test

	public void testPOSTStringBody() {

      

        String url = "http://ezifyautomationlabs.com:6565/educative-rest/students";



        LOG.info("Step - 1 : Target resource ( server ) : " + url);

        

        String body = "{\"first_name\": \"Jack\", \"last_name\": \"Preacher\", \"gender\": \"Male\" }";

        LOG.info("Step - 2 : Message body: " + body);

        

        LOG.info("Step - 3 : Send a POST Request");

        Response response = RestAssured.given()

                .header("accept", "application/json")

                .header("content-type", "application/json")

                .body(body)

                .post(url)

                .andReturn();

        

        LOG.info("Step - 4 : Print the response message and assert the status response code is 201 - Created");

        response.getBody().prettyPrint();	

		assertTrue(response.getStatusCode() == 201);

	        

	}

}

Let’s understand the example code above.

The code above uses the TestNG and Rest Assured libraries for automating the HTTP POST request and sends a string message for creating a new resource.
