If I undertand correctly, you're trying to test that your string message is
being set as the text of your TextMessage object.

You might want to change your test like this:

// Junit test
public void testJmsMessageCreation()
{
    SomeDataObject data = new SomeDataObject();
    data.fillWithSomeExtremelyImportantInformation();

    MockQueueSession mqs = new MockQueueSession();

    MockTextMessage mockMessage = new MockTextMessage();
    mockMessage.setExpectedText(putYourExpectedValueHere);
    mqs.setupTextMessage(mockMessage);

    TextMessage tm = createJmsMessage(data, mqs);

    // What to do here? getText() returns null :-(

    // Don't actually have to do anything here in this case,
    // although it's good practise to call verify on mockobjects that have
expectations, so:
    mockMessage.verify();
}

The nice thing is that the test assertion is inside the MockTextMessage
class and it will break immediatly if the value fed to setText() is not the
expected value. Keep in mind though that it's not always the case for other
test assertions so you should call verify() at the end of the test.

Hi Vincent and thanks for a quick response. (I didn't see your reply on the
message thread so I'm backfiring this to you :)

Here's a raw version of what I'm trying to do:

// Method under test
public javax.jms.Message createJmsMessage(SomeDataObject data,
javax.jms.QueueSession qs)
{
    String message = data.getDesiredMessage();
    javax.jms.TextMessage tm = qs.createTextMessage( message );
    return tm;
}

// Junit test
public void testJmsMessageCreation()
{
    SomeDataObject data = new SomeDataObject();
    data.fillWithSomeExtremelyImportantInformation();

    MockQueueSession mqs = new MockQueueSession();
    TextMessage tm = createJmsMessage(data, mqs);

    // What to do here? getText() returns null :-(
}

Am I missing something? The problem is probably that I don't have access to
the MockTextMessage before I call the domain code, and that's maybe not the
way MockObjects are used in general.  (I'm a newbie by the way, but used
JUnit for quite a while now and I like the MO idea a lot).

Kindest regards,
Hlodver

Hi Hlodver,

The idea when testing your code against MockTextMessage is that you want to
make sure that value fed to setText() by the code under test is the value
you expect to receive. On the other hand, the value returned by the
getText() method is used to test the behaviour of your code when it calls
getText(). Use that value to simulate different text values in your
TextMessage and see how the code under test reacts to these values. So it's
not a classic getter/setter pattern.

As for your problem, could you give more explanations on what you're trying
to test and maybe post some code snippets. We'll try to work it out then.

Hi,
Why doesn't JMS MockTextMessage.getText() return the value set in
MockTextMessage.setText()?

(I'm using a factory method which returns a new TextMessage using
QueueSession.createTextMessage(),
and I can't call setExpectedText before I call setText() on the message)

Regards,
Hlodver
