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

Learn REST and SOAP API Test Automation in Java

This lesson is a continuation of ***[Creating SOAP Client Project](https://www.educative.io/courses/learn-rest-soap-api-test-automation-java/creating-a-soap-client-project)*** lesson.

# Copying WSDL

For creating the web service client, we need the `WSDL` file that holds the information about the web service request-response formats and where the service is hosted.

A sample WDSL file is already given in ***[SOAP Messages and WSDL](https://www.educative.io/courses/learn-rest-soap-api-test-automation-java/soap-messages-and-wsdl#web-services-description-language-wsdl)*** lesson.

Download the `WSDL` XML document for the web service under test and place it under `src/main/resources`. For the demonstration, let's assume the name of the WSDL file is `students.wsdl`.

Please ensure the WSDL file name and the location is mentioned correctly in **build.gradle** in the case of `Gradle` or **pom.xml** in the case of `Maven`.


# Build the project

## `Gradle`

Please ensure the current folder structure looks like the following:

![](/api/collection/5455247108472832/6211777403551744/page/4873619021758464/image/5690008888410112)

After adding Gradle to classpath and creating `build.gradle` with the above content, run the following command to build the project. 

```
gradle clean build
```

After running the above command, all the request-response classes in accordance to the `src/main/resources/students.wsdl` will be generated under `build/generated-sources/jaxb`.

## `Maven`

Please ensure the current folder structure looks like the following:

![](/api/collection/5455247108472832/6211777403551744/page/4873619021758464/image/5001908688257024)

After adding Maven to classpath and creating `pom.xml` with the above content, run the following command to build the project. 

```
mvn clean compile
```

After running the above command, all the request-response classes in accordance to the `src/main/resources/students.wsdl` will be generated under `target/generated-sources/jaxb`.


# Creating SOAP client

Create a package `io.educative.soap` under `src/main/java`, create `WebServiceClient.java` under `io.educative.soap` and copy the following contents into it.

```java
package io.educative.soap;

import javax.annotation.PostConstruct;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.util.ClassUtils;
import org.springframework.ws.client.core.WebServiceTemplate;

import io.educative.soap_automation.GetStudentsRequest;

@Configuration
public class WebServiceClient {

	private Jaxb2Marshaller marshaller = new Jaxb2Marshaller();

	@PostConstruct
	public void init() throws Exception {
		marshaller.setPackagesToScan(ClassUtils.getPackageName(GetStudentsRequest.class));
		marshaller.afterPropertiesSet();
	}

	@Bean
	public WebServiceTemplate getWebServiceTemplate() {
		return new WebServiceTemplate(marshaller);
	}

}
```

The import statements and `GetStudentsRequest.class` might change depending upon the SOAP request class.

`Jaxb2Marshaller` instance is needed to convert the response XML to Java objects.

`WebServiceTemplate` is used to make web service calls, which we will learn in the next lesson.

---

In this lesson, we learned how to create a test project, get the WSDL file, build the project and create the web service client. In the next lesson, we will learn how to use this web service client to make web service calls over HTTP. 



In this lesson, we will see how to copy the WSDL document, build the project and create the SOAP client for making web service calls over HTTP.
