Serenity Unit tests fail when using @DefaultUrl("classpath:<static-site.html>")

[nbarrett]

If I wish to create some unit tests to TDD my page objects, and I use the following static website pattern:

@DefaultUrl("classpath:static-site/error-modal-on-search/my-application.html")
public class SearchResultsErrorModalPage extends PageObject {
}

and then reference this as follows:

    @Managed(driver = "htmlunit")
    WebDriver browser;
    Actor actor = new Actor("MDM");
    actor.can(BrowseTheWeb.with(browser));

    SearchResultsErrorModalPage searchResultsErrorModalPage;
    givenThat(actor).attemptsTo(Open.browserOn().the(searchResultsErrorModalPage));

I find that when I run @Test cases individually, they work fine but when I run the whole test class or run all tests in the suite some fail. The nature of failure is that the website I expect to be there is not being rendered properly. Is there a different way to scope/instantiate the page object correctly/reliably?

Could be an HtmlUnit bug, have you tried with other drivers?

hmm, no it actually fails on all browsers. Error is org.openqa.selenium.NoSuchElementException: Returned node was not a DOM element, Say 1 out of 4 tests fail - oddly enough it's the last one each time!

I see this sometimes when I run all tests in net.serenitybdd.screenplay.webtests directory in the serenity-screenplay-webdriver project which also use the static html site pattern.
