SOAP WebService sample

This sample uses SOAP web services to add new todo entries on the todo app system under test. You can read more about the Citrus SOAP features in reference guide

Objectives

The todo-list sample application manages todo entries. The application provides a SOAP web service endpoint for adding new entries and listing all entries.

The sample tests show how to use this SOAP endpoint as a client. First we define the schema and a global namespace for the SOAP messages.

@Bean
public SimpleXsdSchema todoListSchema() {
    return new SimpleXsdSchema(new ClassPathResource("schema/TodoList.xsd"));
}

@Bean
public XsdSchemaRepository schemaRepository() {
    XsdSchemaRepository schemaRepository = new XsdSchemaRepository();
    schemaRepository.getSchemas().add(todoListSchema());
    return schemaRepository;
}

@Bean
public NamespaceContextBuilder namespaceContextBuilder() {
    NamespaceContextBuilder namespaceContextBuilder = new NamespaceContextBuilder();
    namespaceContextBuilder.setNamespaceMappings(Collections.singletonMap("todo", "http://citrusframework.org/samples/todolist"));
    return namespaceContextBuilder;
}

The schema repository holds all known schemas in this project. Citrus will automatically check the syntax rules for incoming messages then. Next we need a SOAP web service client component:

@Bean
public SoapMessageFactory messageFactory() {
    return new SaajSoapMessageFactory();
}

@Bean
public WebServiceClient todoClient() {
    return CitrusEndpoints
        .soap()
            .client()
            .defaultUri("http://localhost:8080/services/ws/todolist")
        .build();
}

The client connects to the web service endpoint on the system under test. In addition to that we define a SOAP message factory that is responsible for creating the SOAP envelope.

Now we can use the web service client in the Citrus test with SOAP request and attachment.

$(soap()
    .client(todoClient)
    .send()
    .soapAction("addTodoEntry")
    .body(new ClassPathResource("templates/addTodoEntryRequest.xml")));

$(soap()
    .client(todoClient)
    .receive()
    .body(new ClassPathResource("templates/addTodoEntryResponse.xml")));

The Citrus test sends a request with attachment data. The attachment is transmitted as text data via Http to the server. The todo-list WebService endpoint will recognize the attamchent data and add it to the todo entry. So we can expect the attachment data to be returned in the list of todo entries.

$(soap()
    .client(todoClient)
    .receive()
    .body(new ClassPathResource("templates/addTodoEntryResponse.xml")));

$(soap()
    .client(todoClient)
    .send()
    .soapAction("getTodoList")
    .body(new ClassPathResource("templates/getTodoListRequest.xml")));

And in the expected message payload we validate the attachment data returned by the server.

<todo:getTodoListResponse xmlns:todo="http://citrusframework.org/samples/todolist">
  <todo:list>
    <todo:todoEntry>
      <todo:id>@ignore@</todo:id>
      <todo:title>${todoName}</todo:title>
      <todo:description>${todoDescription}</todo:description>
      <todo:attachment>
        <todo:cid>myAttachment</todo:cid>
        <todo:contentType>text/plain</todo:contentType>
        <todo:data>citrus:encodeBase64('This is my attachment')</todo:data>
      </todo:attachment>
    </todo:todoEntry>
  </todo:list>
</todo:getTodoListResponse>

Run

NOTE: This test depends on the todo-app WAR which must have been installed into your local maven repository using mvn clean install beforehand.

The sample application uses Maven as build tool. So you can compile, package and test the sample with Maven.

 mvn clean verify -Dsystem.under.test.mode=embedded

This executes the complete Maven build lifecycle. The embedded option automatically starts a Jetty web container before the integration test phase. The todo-list system under test is automatically deployed in this phase. After that the Citrus test cases are able to interact with the todo-list application in the integration test phase.

During the build you will see Citrus performing some integration tests. After the tests are finished the embedded Jetty web container and the todo-list application are automatically stopped.

System under test

The sample uses a small todo list application as system under test. The application is a web application that you can deploy on any web container. You can find the todo-list sources here. Up to now we have started an embedded Jetty web container with automatic deployments during the Maven build lifecycle. This approach is fantastic when running automated tests in a continuous build.

Unfortunately the Jetty server and the sample application automatically get stopped when the Maven build is finished. There may be times we want to test against a standalone todo-list application.

You can start the sample todo list application in Jetty with this command.

 mvn jetty:run

This starts the Jetty web container and automatically deploys the todo list app. Point your browser to

http://localhost:8080/todolist/

You will see the web UI of the todo list and add some new todo entries.

Now we are ready to execute some Citrus tests in a separate JVM.

Citrus test

Once the sample application is deployed and running you can execute the Citrus test cases. Open a separate command line terminal and navigate to the sample folder.

Execute all Citrus tests by calling

 mvn verify

You can also pick a single test by calling

 mvn verify -Dit.test=<testname>

You should see Citrus performing several tests with lots of debugging output in both terminals (sample application server and Citrus test client). And of course green tests at the very end of the build.

Of course you can also start the Citrus tests from your favorite IDE. Just start the Citrus test using the TestNG IDE integration in IntelliJ, Eclipse or Netbeans.
