Junit test case for the below method

Question

I am still new to JUnit testing. I am writing junit tests for this method:

public void LoadApplet(JPanel panel) {
    AppletClass applet = new AppletClass();

    applet.init();
    panel.add(applet,BorderLayout.CENTER);
    applet.start();
}

Answer 1

I wrote the unit test this way and it worked:

public void TestLoadApplet() {
  AppletClass instance = new AppletClass();

  JPanel panel = new JPanel(); // Creating a empty panel
  instance.LoadApplet(panel);
  assertEquals("java.awt.BorderLayout", panel.getLayout().getClass().getName());
  assertEquals("Applets.AppletClassName", panel.getComponent().getClass().getName());
  }
