Protractor Dismiss Alerts If Open

Question

I am running with protractor and cucumber. For a number of tests, the outcome is problematic, and will sometimes produce an alert box.

what I'd like to do is in my beginning method for each test, check to see if there is an alert box, and then close/dismiss it. Then continue. The problem I'm facing is, I can't guarantee that there will always be an alert box, and if there isn't one, I get a NoSuchAlertError: no alert open and the entire script stops.

Is there any way around this?

Current code:

try {
  browser.switchTo().alert().dismiss();
}catch(err){

}

Solution 1

driver.switchTo().alert().then(
    function (alert) { alert.dismiss(); },
    function (err) { }
);

This worked for me. It'll dismiss the alert if it is there, and do nothing if it isn't.

Change dismiss() for accept() if you want to accept the alert (OK) instead of dismissing (Cancel).

Solution 2

//dismiss "wrong credentials" alert
browser.driver.sleep(2000);

browser.switchTo().alert().accept().then(null, function(e) {
  if (e.code !== webdriver.ErrorCode.NO_SUCH_ALERT) {
  throw e;
  }
});

This worked for me in Protractor 2.0. I am sure there is a better solution that doesn't involve using sleep(). After a couple hours of frustration, though, I was just happy to see something that worked.

Solution 3

As in https://code.google.com/p/selenium/wiki/WebDriverJs, you could try/catch to handle the alert

try {
    driver.switchTo().alert().dismiss();
} catch (NoAlertPresentException ignored) {
}

Solution 4

try to override the javascript method to confirm a dialogue if exist

  window.confirm = function() { return true; }

this solution works for me with capybara and cucumber
