GET, POST, PUT, PATCH, DELETE Requests - Rest Assured Examples

Post Views: 936

In this tutorial, you will learn how to send HTTP Requests using Rest Assured API Testing Library. We are going to cover all the Request types in this Rest Assured Examples article – GET, POST, PUT, PATCH and DELETE.

Rest Assured Examples - GET, POST, PUT, PATCH and DELETE...!!! Share on X

Rest Assured Library Dependency Configuration:

Add the below-mentioned dependency to your maven project’s pom.xml.

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>3.3.0</version>
    <scope>test</scope>
</dependency>

<groupId>io.rest-assured</groupId>

<artifactId>rest-assured</artifactId>

</dependency>

Note: you can choose the ‘version’ of your choice.

Now, we are all set to get into the REST-assured HTTP API Requests.

In the examples below, we will test the ‘reqres.in – Sample Rest API’ which is available here. This page contains Fake Online REST API for the testing purpose which we are going to use for various CRUD operations.

In this Article, we are going to cover:

GET REQUEST

The HTTP GET request is used to request a resource from the server. In the example below, we are going to use get() method of Rest Assured Java Library.

/**

import static org.testng.Assert.assertEquals;
import static org.testng.Assert.assertTrue;
import org.testng.annotations.Test;
import io.restassured.RestAssured;
import io.restassured.response.Response;
public class RestAssured_GET_Example {
	@Test
	public void getExample() {
		RestAssured.baseURI = "https://reqres.in/api";
		Response response = null;
		try {
			response = RestAssured.given()
					              .when()
					              .get("/users/2");
		} catch (Exception e) {
			e.printStackTrace();
		}
		System.out.println("Response :" + response.asString());
		assertEquals(200, response.getStatusCode());
		assertEquals("janet.weaver@reqres.in",response.jsonPath().getString("data.email"));
		assertTrue(response.jsonPath().getString("data.first_name").contains("Janet"));
	}
}

GET REQUEST WITH QUERY PARAMETERS

Query Parameter is used to filter or sort the resources. In the example below, we are going to use queryParam() with the get() call.

POST REQUEST

The HTTP POST request is used to send data to a server to create the resource. In the example below, we are going to use post() method of Rest Assured Java Library and sending the data while making the call.
