REST Assured Tutorial 12 – Let’s Write First DELETE Request in REST Assured

As a part of End to End REST Assured Tutorial , in this post We will write first DELETE request in REST assured.

I will strongly recommended you to learn basics of API testing from here.

To learn what is DELETE request and how can you hit a DELETE request in Postman tool, must refer this post.

We will delete a booking details using “DeleteBooking” API provided by Restful Booker. Once deleted, we will verify it using GetBooking API.

Refer Delete Booking API documentation to understand how authentication and body need to be provided to request.

Below points summarize the above documentation :-

1. We need to pass booking id which you want to delete in URI. E.g. https://restful-booker.herokuapp.com/booking/1 where “1” is booking id.
2. Authentication token need to pass as cookie. Cookie name is “token” and value is generated auth token. ‘Cookie: token=<generatedToken>’.
3. You don’t required to pass body to DELETE request.

Let’s see existing details of a Booking ID 1 using Postman:-

Let’s generate token which I have already covered in Previous post. Perform all above steps in Postman tool as of now. We will see in upcoming posts to chain different requests in REST Assured.

Generate Token:-

Let’s write DELETE request in REST Assured:-

Non-BDD Style:-

package RestfulBooker.deleteExamples;

import io.restassured.RestAssured;
import io.restassured.response.Response;
import io.restassured.response.ValidatableResponse;
import io.restassured.specification.RequestSpecification;

public class NonBDDDeleteRequest {

        public static void main(String[] args) {

                // Create a request specification
                RequestSpecification request = RestAssured.given();

                // Setting a cookie for authentication as per API documentation
                request.cookie("token", "f4e70e7b9bbcd05");
                // Adding URI
                request.baseUri("https://restful-booker.herokuapp.com/booking/1");
                

                // Calling PUT method on URI. After hitting we get Response
                Response response = request.delete();

                // Printing Response as string
                System.out.println(response.asString());

                // Get Validatable response to perform validation
                ValidatableResponse validatableResponse = response.then();

                // Validate status code as 201 as per API documentation
                validatableResponse.statusCode(201);

                // Validate if booking is actually deleted. 
                RequestSpecification getRequestSpec = RestAssured.given();
                
                // Adding URI
                getRequestSpec.baseUri("https://restful-booker.herokuapp.com/booking/1");
                
                // Calling GET request
                Response res = getRequestSpec.get();
                
                // Get Validatable response to perform validation
                ValidatableResponse valRes = res.then();
                
                // It will check if status code is 404 as booking id should not be found
                valRes.statusCode(404);
                

        }
}

BDD Style:-

package RestfulBooker.deleteExamples;

import io.restassured.RestAssured;

public class BDDStyleDeleteRequest {

        public static void main(String[] args) {
                

                // Delete Booking

                //GIVEN
                RestAssured
                        .given()
                                        .baseUri("https://restful-booker.herokuapp.com/booking/1")
                                        .cookie("token", "f7dddb1093eab19")
                        // WHEN
                        .when()
                                        .delete()
                        // THEN
                        .then()
                                        .assertThat()
                                        .statusCode(201);
                
                // Verifying booking is deleted
                // Given
                RestAssured
                    .given()
                                    .baseUri("https://restful-booker.herokuapp.com/booking/1")
                // When
                        .when()
                                        .get()
                // Then
                        .then()
                                        .statusCode(404);

        }
}

Note:- You need to generate access token every time you hit the request otherwise you will get error code as 403.
