 public JPopupMenu createPopupMenu() 
{
        return MenuFactory.getDefaultAssertionMenu();
}

When a user right-clicks on the component in the test tree, or selects the edit menu when the component is selected, the component will be asked to return a JPopupMenu that provides all the options available to the user from this component.

This implementation returns menu items appropriate for most assertion components.

 protected JPanel createScopePanel() 
{
        assertionScopePanel = new AssertionScopePanel();
        return assertionScopePanel;
}

Create the scope settings panel.

 public Collection getMenuCategories() 
{
        return Arrays.asList(new String[] { MenuFactory.ASSERTIONS });
}

This is the list of menu categories this gui component will be available under. This implementation returns org.apache.jmeter.gui.util.MenuFactory#ASSERTIONS , which is appropriate for most assertion components.

 protected  void saveScopeSettings(AbstractScopedAssertion assertion) 
{
        if (assertionScopePanel.isScopeParent()){
            assertion.setScopeParent();
        } else

            assertion.setScopeChildren();
        } else {
            assertion.setScopeAll();
        }
}

Save the scope settings in the test element.

 protected  void showScopeSettings(AbstractScopedAssertion assertion) 
{
        String scope = assertion.fetchScope();
        if (assertion.isScopeParent(scope)) {
                assertionScopePanel.setScopeParent();                
        } else if (assertion.isScopeChildren(scope)){
            assertionScopePanel.setScopeChildren();
        } else {
            assertionScopePanel.setScopeAll();
        }
}

Show the scope settings from the test element.
