C # Webdriver - Assert page name fails before page load

Question

This problem started when I switched from testing on the www website to my version of localhost. While working in VS 2012, I will start debugging so that localhost is active, disconnect the process so that I can test it, and then run any test that I like. For a very simple example:

[Test] public void CanGoToHomePage() { Pages.HomePage.Goto(); Assert.IsTrue(Pages.HomePage.IsAt()); } 

And the functions that it refers to here:

  public class HomePage { const string Url = "http://localhost:3738"; const string HomepageTitle = "FunnelFire - Home Page"; public void Goto() { Browser.Goto(Url); } public bool IsAt() { return Browser.Title == HomepageTitle; } } 

And the real selenium code is here:

  public static class Browser { static IWebDriver webDriver = new FirefoxDriver(); public static void Goto(string url) { webDriver.Manage().Window.Maximize(); webDriver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10)); webDriver.Url = url; } } 

Now the problem. The 10 second implicit wait that I added in the browser successfully waits no more than 10 seconds after the page loads to find out if it can find any information I want to find, this is not a problem.

As I said, after I switched to testing on the local host, suddenly I had a strange problem when the page starts loading (i.e. the screen is still completely white, nothing is finished), or even sometimes the next page is just barely finished and all of a sudden the test will simply go up and fail, indicating an IsAt confirmation returning false, even if the page that it loaded was correct. I could run this test right away again and it would pass without problems. Run it a third time, and it may accidentally fail again. I'm honestly not sure what causes the problem and any help would be appreciated!

Implicit expectations only work for finding items. To expect the page title to be a specific value, you will want to use an explicit wait. You can write your own version of this template, but in .NET bindings, the WebDriver.Support.dll assembly has a WebDriverWait class to help with this. Its use will look something like this:

 // WARNING! Untested code written from memory below. It has not // been tested or even compiled in an IDE, so may be syntactically // incorrect. The concept, however, should still be valid. public void WaitForTitle(IWebDriver driver, string title, TimeSpan timeout) { WebDriverWait wait = new WebDriverWait(driver, timeout); wait.Until((d) => { return d.Title == title; }); } 

You can even change your IsAt method to use this template by catching a WebDriverTimeoutException and returning false if the wait function is disabled.
