Question

I need to detect when the url in the browser changes whether it was because of click on a link, a form post or I changed the url in code.

I need it because I’m creating an object to represent the page and I need to dispose recreate it when the url changes.

Here is what I have tried so far:

private string _pageUrl;
protected T _page = default(T);
protected T Page
{
    get
    {
        if (_page == null || UrlHasChanged())
        {
            _page = GetPage<T>();
            SetPageUrl();
        }
        return _page;
    }
}

private bool UrlHasChanged()
{
    var driver = Session.GetDriver();
    return driver.Url != _pageUrl;
}

public void SetPageUrl()
{
    _pageUrl = Session.GetDriver().Url;
}

This works in most cases but it fails when the test goes forward a page and then goes back to the initial page.

I need a way to detect when the url changes so I can reset the _page field.

I’m a Java developer, so, I search in the C# documentation what looked similar to the Java API. I think you should use the EventFiringWebDriver :

EventFiringWebDriver firingDriver = new EventFiringWebDriver(driver);
firingDriver.NavigatingBack += new EventHandler<WebDriverNavigationEventArgs>(...);
firingDriver.NavigatedBack += new EventHandler<WebDriverNavigationEventArgs>(...);
firingDriver.NavigatingForward += new EventHandler<WebDriverNavigationEventArgs>(...);
firingDriver.NavigatedForward += new EventHandler<WebDriverNavigationEventArgs>(...);

I looked at the unit tests and I found this one that may be useful for you :
