selenium 2.4.0, how to check for presence of an alert

Question

Before using selenium 2.4.0 I had the following code working:

alert = page.driver.browser.switch_to.alert
if alert.text
  ....
end

Selenium 2.4.0 contains the change "* Raise in switch_to.alert when no alert is present.", so I get a No alert is present (Selenium::WebDriver::Error::NoAlertOpenError) exception.

How can I check for the presence of an alert with selenium-web-driver 2.4.0?

Answer 1

I implemented a method to handle this in Ruby that I think is pretty clean:

def alert_present?
  begin
    session.driver.browser.switch_to.alert
    puts "Alert present! Switched to alert."
    true
  rescue
    puts "No alert present."
    return false
  end
end

Answer 2

Here is one option:

driver.switch_to.alert.accept rescue Selenium::WebDriver::Error::NoAlertOpenError

This will click OK on the alert if one is present, else it will fail gracefully (silently).
