TestNG SOAP

In software development, microservices and APIs are used for writing business logic. API testing has become an important component in the testing cycle, as it can be used to test the functionality, integration flows, load and performance.

In this course, you will learn how to perform REST and SOAP API test automation. This course covers all the required details for you to start writing API and integration tests from scratch. It will also prepare you for test automation interviews.

As part of the course, you will be able to download a sample API automation framework. You can use this for writing automation tests of modules or applications, or just extend and customize it for your own use

# `HTTP DELETE` request automation

In this lesson, we will discuss deleting a record using the `DELETE` request method.

## **Example 1 – *DELETE request for a particular id***
 
* `HTTP` Method: *DELETE*
* Target URL: `http://ezifyautomationlabs.com:6565`
* Resource path: *`/educative-rest/students/{id}`*
* Take a look at the code below:

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;

import com.fasterxml.jackson.annotation.JsonProperty;

public class DELETERequestTest {

	private static Logger LOG = LoggerFactory.getLogger(DELETERequestTest.class);

	@Test
	public void testDelete() {

        String url = "http://ezifyautomationlabs.com:6565/educative-rest/students";

		LOG.info("Step - 1 : Create a new Student [POST]");
		Student body = new Student("NewUser1", "DeleteUser", "Female");
		Response response = RestAssured.given().header("accept", "application/json")
				.header("content-type", "application/json").body(body).post(url).andReturn();

		LOG.info("Created Student Record");
		response.getBody().prettyPrint();

		String id = response.getBody().jsonPath().getString("id");
		LOG.info("Get the created Student ID: " + id);

		LOG.info("Step - 2 : Delete the created record. [DELETE ]");
		String url1 = url + "/" + id;
		Response response1 = RestAssured.given().delete(url1).andReturn();

		LOG.info("Step - 3 : Print the response message and assert the status");
		LOG.info("Response Status Code: " + response1.getStatusCode());
		assertTrue(response1.getBody().prettyPrint().isEmpty());
		assertTrue(response1.getStatusCode()==204);
		LOG.info("Student with id: " +id+ " is deleted");
	}

}
	 // This POJO class will be used for serialization and deserialzation of the data
	class Student {

		public Student(String firstName, String lastName, String gender) {
			this.firstName = firstName;
			this.lastName = lastName;
			this.gender = gender;
		}

		@JsonProperty("id")
		Long id;

		@JsonProperty("first_name")
		String firstName;

		@JsonProperty("last_name")
		String lastName;

		@JsonProperty("gender")
		String gender;
	}



**Let's understand this example code.**

The code above uses the `TestNG` and `Rest Assured` libraries for automating the `HTTP` DELETE request and sends a Student `id` which has to be deleted.

* **Step 1** -- create a new Student using the `POST` request
    ```
    Student body = new Student("NewUser1", "DeleteUser", "Female");
	Response response = RestAssured.given()
						.header("accept", "application/json")
						.header("content-type", "application/json")
						.body(body)
						.post(url)
						.andReturn();

	LOG.info("Created Student Record");
	response.getBody().prettyPrint();
    ```

* **Step 2** -- gets the created Student `id` and `Delete` that Student's record using `delete(url1)` method and returns the `Response` object using `andReturn()` method
    ```
   String id = response.getBody().jsonPath().getString("id");
	LOG.info("Get the created Student ID: " + id);

	LOG.info("Step - 2 : Delete the created record. [DELETE ]");
	String url1 = url + "/" + id;
	Response response1 = RestAssured.given().delete(url1).andReturn();
    ```

* **Step 3** -- verifies that the Student's record is deleted and the `Response` body is empty. `response1.getBody().prettyPrint().isEmpty()` and the response status code is `204`

    ```
    LOG.info("Step - 3 : Print the response message and assert the status");
	LOG.info("Response Status Code: " + response.getStatusCode());
	assertTrue(response1.getBody().prettyPrint().isEmpty());
    assertTrue(response1.getStatusCode()==204);
	LOG.info("Student with id: " +id+ " is deleted");
    ```  

In this lesson, we will learn how to automate a DELETE request for an existing record.
