Marathon is a very nice tool to test swing applications. You can write test scripts using python, or you can have Marathon record your actions. The result of this is a python script which looks like this:

useFixture(default)
def test():

    window('My Application')
    click('JTree', '/Someone/Contact Data')
     select('sexComboBox', 'F')
    select('weightFormattedTextField', '90')
    assertText('statusLabel','')
    select('dateOfBirthFormattedTextField', '01.01.1900')
    close() 

You specify which components you’re using by refering to the component name, which you can set using setName() on every component. In jdeveloper you’d expect that if you specify name in the property sheet of a component that jdeveloper would generate a setName call in your code. This is not the case however. Instead it changes the instance name of the component, which isn’t bad either, but not very helpfull if you’re creating marathon scripts. You’re test scripts will be a lot less readable. In the example above, i didn’t manually call setName for the JTree component. If i’d had 3 JTree components they would have referred to as JTree, JTree1, JTree2.

I’ve created a small utility which will set the name of a component and it’s child components by taking the instance name and calling setName on the component. Might be usefull if you’re using Marathon.
