Simple radio button unit test using gwtmockito/mockito?

[Jonathan Cook]

I wanted to write a simple unit test avoiding GWTTeseCase for an extension of a radio button.

This is the class:

public class DeselectableRadioButton extends RadioButton {

    private Boolean backingValue;

    private final class RadioButtonClickHandler implements ClickHandler {

        public RadioButtonClickHandler(Boolean value) {
            backingValue = value;
        }

        @Override
        public void onClick(ClickEvent event) {
            RadioButton button = (RadioButton) event.getSource();
            if (!backingValue) {
                button.setValue(true);
                backingValue = true;
            } else {
                button.setValue(false);
                backingValue = false;
            }
        }
    }

    /**
     * Constructor creates radio button with name and value
     *
     * @param name The name to be assigned to the radio button
     * @param value The default value to be given to the radio button
     */
    public DeselectableRadioButton(String name, Boolean value) {
        super(name);
        this.setValue(value);
        setupHandlers(value);
    }

    private void setupHandlers(Boolean value) {
        addClickHandler(new RadioButtonClickHandler(value));
    }

}

I was looking at some examples with GWTMockito such as: https://gist.github.com/nbuesing/7090529

But it doesn't seem possible with the current implementation of the widget I have?

Thanks for any help
