uispec4j testing application java

Question

i have a little application, Phonebook, and i want test it. i have some problem with uispec4j, i write this:

public class TestRubricaBlack extends UISpecTestCase{

@BeforeClass
public void setUp(){
    setAdapter(new MainClassAdapter(Rubrica.class, new String[0]));

}

public void testMamma(){

    Window window=getMainWindow();
    assertEquals(true,window.getButton("index").isVisible());
}
}

when i try to execute the test, i have this error, the problem is on function getMainWindow():

The stack trace tells me the button named "index" was not found. Not being psychic or having your code available, I have no idea why. Here are my best guesses:

You did not define a button named "index"
You misspelled the name
The button is defined on a panel and not directly on the main window

I am having trouble with the third item, which is how I came across your post. I may be wrong, but it seems that uispec4j does not automatically look in containers like panels and, in my case, JScrollPanes.

If I find I am wrong about this behavior, I will update my reply. If I come up with a solution, maybe a custom matcher, I will post it as well.

Good luck.

I am wrong! I had a type in the name of my component. uispec4j will search the component hierarchy and find the component in sub-panels. So check for item 1 or 2. — Steve Gelman, Oct 23 '12 at 15:36
