Make IAlert as Observer

Question

I\'m using last selenium some websites have randomly popup messages that stops the normally test process

What i\'m thinking is that i need to do IAlert as Observer patte

Answer 1

Since popup would matter when you are trying to do something else, I will suggest the following approach: EventFiringWebDriver allows you to define custom code that will run right before or after a particular event. See an example here.

Unfortunately I didn't write anything on .Net for a long time, so my C# skills are rusty. So roughly it would look like this:

IWebDriver driver = new FirefoxDriver();
EventFiringWebDriver eventDriver = new EventFiringWebDriver(driver);
// add all relevant events, for example before clicking on something:
eventDriver.ElementClicking = new EventHandler(checkPopup);
driver = eventDriver; // only need EventFiringWebDriver

And then

static void checkPopup(object sender, OpenQA.Selenium.Support.Events. WebElementEventArgs e) {
     EventFiringWebDriver driver = (sender as OpenQA.Selenium.Support.Events.EventFiringWebDriver);
     try {
         Alert alert = driver.SwitchTo().Alert();
         alert.accept();
     }
     catch (NoAlertPresentException ex) { 
         // nothing to do - just continue
     }
}

So now, every time script is about to click something, it would first check for popup and accept it if needed.
