I might do
class PageA extends Page {
public PageA() {
add(new Link("toBPage") {
@Override
public void onLinkClicked() {
goToPageB();
}
);
}
protected goToPageB() {
...
and overriding goToPageB() in the test.
This technique has even a fancy name in the excellent
_Working Effectively with Legacy Code_ by Michael Feathers,
so maybe it's a kludge to use it in non-legacy code. But
it's simple and it works.
