Mule - JUnit Send requests - Best practice

Question

This is the mule flow that I use to the tests:

HTTP Listener > Logger (Message) > HTTP Request POST > Logger (Response)

In my mule project I have 5 classes. This is an example:

@XmlRootElement
public class Car {

    String name;
    String color;

    public Car() {
        super();
    }

    public Car(String name, String color) {
        super();
        this.name = name;
        this.color = color;
    }

    public String getName() {
        return name;
    }
    @XmlElement
    public void setName(String name) {
        this.name = name;
    }
[More Setters and Getters...]
}

I asign the element @XmlRootElement to class and @XmlElement to setters.

Then, I have a main class when I test the flow with Config Resources:

public class JUnitSend extends FunctionalTestCase {

    @Override
    protected String getConfigResources() {
        return "send-xml.xml";
    }      

    public String getName() {
        return "Mule Server Test";
    }

    public Car myCar()
    {       
        Car myCar = new Car();
        myCar.setName("Ferrari");
        myCar.setColor("Red");

        return myCar;
    }

    @Test
    public void sendXML() throws Exception {

        JAXBContext jaxbContext = JAXBContext.newInstance(Car.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        StringWriter sw = new StringWriter();

        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        jaxbMarshaller.marshal(myCar(), sw);
        String xmlString = sw.toString();

        MuleClient client = new MuleClient(muleContext);

        MuleMessage result = client.send("http://localhost:8090/", xmlString, null);

        assertEquals("Hello", result.getPayloadAsString());
    }
}

But I want to test it with the remaining 4 classes.

What is the best practises to test with the other classes?

Answer 1

How about something like this:

    public class JUnitSend extends FunctionalTestCase {

    @Override
    protected String getConfigResources() {
        return "send-xml.xml";
    }      

    public String getName() {
        return "Mule Server Test";
    }

    public Car myCar()
    {       
        Car myCar = new Car();
        myCar.setName("Ferrari");
        myCar.setColor("Red");

        return myCar;
    }

private String marshallObject(Object object)
{
   JAXBContext jaxbContext = JAXBContext.newInstance(Car.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        StringWriter sw = new StringWriter();

        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        jaxbMarshaller.marshal(object, sw);
        return sw.toString();
}

    @Test
    public void testSendXml_car() throws Exception {        

        MuleClient client = new MuleClient(muleContext);

        MuleMessage result = client.send("http://localhost:8090/", marshallObject(myCar(), null);

        assertEquals("Hello", result.getPayloadAsString());
    }

@Test
    public void testSendXml_otherObject() throws Exception {        

        MuleClient client = new MuleClient(muleContext);

        MuleMessage result = client.send("http://localhost:8090/", marshallObject(myOtherObject(), null);

        assertEquals("Hello", result.getPayloadAsString());
    }



}

And yes getting MuleClient from context is slightly more efficient:

MuleClient client = muleContext.getClient();
