In this blog post, we will explore how to test JAX-WS (Java API for XML Web Services) applications using Arquillian, a testing framework for Java applications. Testing web services is crucial to ensure the reliability and integrity of your application’s functionality. Arquillian provides a seamless way to test JAX-WS endpoints by deploying them in a container and executing tests against the deployed application.

Prerequisites

Before we dive into testing JAX-WS with Arquillian, make sure you have the following prerequisites installed:

• JDK (Java Development Kit)
• Maven
• Arquillian
• JAX-WS

Setting up Arquillian for JAX-WS Testing

To get started, let’s first add the necessary dependencies to the pom.xml file of your project:

<dependency>
    <groupId>org.jboss.arquillian.container</groupId>
    <artifactId>arquillian-weld-ee-embedded-1.1</artifactId>
    <version>1.0.0.Alpha1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.jboss.arquillian.protocol</groupId>
    <artifactId>arquillian-protocol-servlet</artifactId>
    <version>1.1.14.Final</version>
    <scope>test</scope>
</dependency>

Next, we need to configure Arquillian to use an embedded container. Create a file named arquillian.xml under the src/test/resources directory and add the following content:

<arquillian xmlns="http://jboss.org/schema/arquillian"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://jboss.org/schema/arquillian
                               http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
    <container qualifier="weld-ee-embedded">
        <configuration>
            <property name="appPath">target/test.war</property>
        </configuration>
    </container>
</arquillian>

Writing the JAX-WS Test

Let’s assume we have a simple JAX-WS endpoint called UserService that exposes a method to retrieve user details. Here’s an example of the endpoint:

@WebService(name = "UserService")
public class UserService {

    @WebMethod
    public User getUser(String userId) {
        // Retrieve user details from the database
        User user = //...
        return user;
    }
}

To test this JAX-WS endpoint with Arquillian, create a new test class called UserServiceTest and add the following code:

@RunWith(Arquillian.class)
public class UserServiceTest {

    @Deployment
    public static WebArchive createDeployment() {
        return ShrinkWrap.create(WebArchive.class, "test.war")
                .addClass(UserService.class);
    }

    @WebServiceRef
    private UserService userService;

    @Before
    public void setup() {
        // Perform any necessary setup before each test
    }

    @Test
    public void testGetUser() {
        // Test the getUser() method
    }
}

In the above test class, we use the @RunWith annotation from Arquillian to run the test. The @Deployment method creates a deployment archive that includes the UserService class. The @WebServiceRef annotation injects an instance of the JAX-WS endpoint into the test class, allowing us to invoke its methods in our tests.

Running the JAX-WS Test

To run the JAX-WS test with Arquillian, execute the following Maven command:

mvn test

This will start the embedded container, deploy the JAX-WS endpoint, and execute the test methods in UserServiceTest. You will see the test results in your console, indicating whether the tests passed or failed.

Conclusion

In this blog post, we learned how to test JAX-WS endpoints using Arquillian. Arquillian provides a simple and efficient way to test JAX-WS applications by deploying them in an embedded container. By writing tests for your JAX-WS endpoints, you can ensure that your web services behave as expected and meet the requirements of your application.
