Java Swing GUI测试巨星JPanel夹具错误

Question

Trying to use FEST to test my GUI, but I'm having a problem trying to access components that are contained inside a custom JPanel (TopPanel extends JPanel). So the code below is failing when trying to reference the "topPane" which exists as a field inside the MainJFrame. What am I doing wrong here?

public class StableAppsUITest {

    private FrameFixture window;
    private JPanelFixture contentFixture;

    @Before
    public void setUp() {
        //Assumes the main class is named "Anagrams" and extends JFrame:
        window = new FrameFixture(new MainJFrame("Title"));
        window.show();
        contentFixture = window.panel("topPanel");

    }

    @Test
    public void shouldEnterAnagramAndReturnTrue() {

        // contentFixture.textBox("mUrlInputTextField").enterText("www.google.com");
    }

    @After
    public void tearDown() {
        window.cleanUp();
    }

}

And here's the stacktrace, in case it's hepful:

Answer 1

Looking at your stacktrace, there is a component of type myapp.ui.TopPanel , but the name is null (myapp.ui.TopPanel[name=null]).

window.panel("topPanel") will search for a JPanel with name "topPanel", so you need to set the name of your component using mTopPanel.setName("topPanel"); , or use a matcher instead.
