Learn REST and SOAP API Test Automation in Java

GET Request

Explore how to automate REST API GET requests using Rest Assured in Java. Learn to fetch all records, retrieve specific records by path or query parameters, and verify responses using assertions and logging. This lesson builds foundational skills for REST API test automation.

We'll cover the following...

HTTP GET request automation

Rest Assured uses given/when/then syntax from behavior-driven development as it makes it easy to read and write tests.

Example 1 – Fetch all student records

  • HTTP Method: GET
  • Target URL: http://ezifyautomationlabs.com:6565/
  • Resource path: /educative-rest/students
  • Take a look at the code below:
Java
import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import static org.hamcrest.Matchers.equalTo;

import org.testng.annotations.Test;

import static org.testng.Assert.assertEquals;

import static org.testng.Assert.assertTrue;



import io.restassured.response.Response;

import io.restassured.RestAssured;



public class GETRequestTest {



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



	@Test

	public void testGetAllStudentRecords() {



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

		

		/**

		 * Example 1 - GET all the existing student's record

		 */

	     LOG.info("Step - 1 : Send GET Request");

		 Response response = RestAssured.given().get(url).andReturn();

		 

		 LOG.info("Step - 2 : Print the JSON response body");

		 response.getBody().prettyPrint();

		 

		 LOG.info("Step - 3 : Assert StatusCode = 200");

		 assertEquals(response.getStatusCode(), 200, "http status code");

		

		 LOG.info("Step - 4 : Verify that the response contains id = 101");

		 LOG.info("list of Student's Id " +response.getBody().jsonPath().getList("id"));

		 assertTrue(response.getBody().jsonPath().getList("id").contains(101));

	}	

}

For logging, we are creating an instance of the Logger interface for GETRequestTest class which internally uses logback for the concrete implementation. ...
