Testing web services with Arquillian and SOAPUI

23 Sep 2023

In this blog post, we will explore how to test web services using Arquillian and SOAPUI. Web services play a crucial role in modern software development, and testing their functionality and reliability is essential to ensure a seamless user experience.

What is Arquillian?

Arquillian is a highly flexible and extensible testing platform for Java applications. It enables developers to easily write integration tests that can be executed in a real container environment, ensuring realistic testing scenarios. Arquillian provides a unified API for testing different components of an application, including web services.

Why SOAPUI?

SOAPUI is a widely-used testing tool for SOAP and REST web services. It allows developers to create, manage, and execute test cases for web services, making it an excellent choice for testing the functionality and performance of web services.

Setting Up the Environment

Before we can start testing web services, we need to set up the necessary environment. Here is a step-by-step guide:

First, you need to have Java Development Kit (JDK) installed on your machine. You can download the latest JDK from the official Oracle website and follow the installation instructions for your operating system.
Next, ensure that you have a build tool like Maven or Gradle installed. We will be using Maven for this example. You can download Maven from its official website and install it following the instructions provided.
Create a new Maven project for your web service tests. Open your terminal or command prompt and navigate to the desired directory. Run the following command to create a new Maven project:
```
mvn archetype:generate -DgroupId=com.example -DartifactId=webservice-tests -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
```
This will create a new Maven project in a directory named webservice-tests.

Open the pom.xml file in the root directory of your project and add the necessary dependencies for Arquillian and SOAPUI. Here is an example configuration:

<dependencies>
    <!-- Arquillian dependencies -->
    <dependency>
        <groupId>org.jboss.arquillian</groupId>
        <artifactId>arquillian-bom</artifactId>
        <version>1.5.0.Final</version>
        <scope>import</scope>
        <type>pom</type>
    </dependency>
    <dependency>
        <groupId>org.jboss.shrinkwrap.resolver</groupId>
        <artifactId>shrinkwrap-resolver-bom</artifactId>
        <version>3.0.0</version>
        <scope>import</scope>
        <type>pom</type>
    </dependency>
   
    <!-- SOAPUI dependencies -->
    <dependency>
        <groupId>com.smartbear.soapui</groupId>
        <artifactId>soapui</artifactId>
        <version>5.6.0</version>
        <scope>test</scope>
    </dependency>
</dependencies>

Run the following command to resolve the dependencies and download them into your project:
```
mvn dependency:resolve
```
Your environment setup is now complete, and you can start writing web service tests using Arquillian and SOAPUI.

Writing Web Service Tests

To write web service tests using Arquillian and SOAPUI, you need to create a test class with proper annotations.

@RunWith(Arquillian.class)
public class WebServiceTests {

    @Deployment(testable = false)
    public static Archive<?> createDeployment() {
        return ShrinkWrap.create(WebArchive.class, "webservice-tests.war")
                .addClasses(YourWebService.class) // Replace with your actual web service class
                .addAsWebInfResource(new ByteArrayAsset("<beans/>".getBytes()), "beans.xml");
    }

    @Test
    @RunAsClient
    public void testWebService() throws Exception {
        WsdlProject project = new WsdlProject();
        WsdlInterface[] interfaces = WsdlImporter.importWsdl(project, "http://your-webservice-url?wsdl");
        WsdlInterface wsdl = interfaces[0]; // Replace with your actual WSDL file
        
        // Perform SOAPUI test operations here
        // Example:
        WsdlOperation operation = wsdl.getOperationByName("someOperation");
        WsdlRequest request = operation.addNewRequest("testRequest");
        request.setRequestContent("some request content");
        WsdlSubmit<?> submit = requestsubmit();
        WsdlSubmitResponse response = submit.getResponse();
        
        // Assert the response using JUnit assertions
        // Example:
        assertEquals("Expected response", response.getResponseContent());
    }
}

Let’s break down the important parts of the code:

@RunWith(Arquillian.class): This annotation tells JUnit to use Arquillian to run the tests.
@Deployment(testable = false): This method creates the deployment archive that will be deployed to the container. Replace YourWebService with the class of your actual web service implementation.
@Test: This annotation marks the method as a test case.
@RunAsClient: This annotation instructs Arquillian to run the test as a client test.
The testWebService() method contains the actual test logic using SOAPUI. Replace the URL, WSDL file, operation name, request content, and expected response with your actual values.

Running the Tests

To run the web service tests, execute the following command in the root directory of your Maven project:

mvn test

Maven will compile and execute the test cases using JUnit and Arquillian. The test results will be displayed in the console output.

Conclusion

Testing web services is critical for delivering reliable and high-quality software solutions. Arquillian and SOAPUI provide a powerful combination for testing web services in a real container environment. By following the steps outlined in this blog post, you can easily set up your testing environment and start writing comprehensive web service tests.
