Function for alert_is_present() and switch_to_alert()

Question

I have code (python / selenium):

    # Alert start
    WebDriverWait(self.driver, 5).until(EC.alert_is_present())
    self.driver.switch_to_alert().dismiss()
    # Alert end

The first row wait for alert in the browser and second row press "Cancel" button to dismiss this window. It works fine. I decided to create 2 functions.

    def alertIsPresent(self, timeout=10):
        WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

    def alertDismiss(self):
        alert = self.driver.switch_to_alert()
        alert.dismiss()

And I call this functions:

    PageObject.alertIsPresent()
    PageObject.alertDismiss()

The last ")" is underlined because "parameter self unfilled"... I'm newest in python, can you give me suggestion?

pageObjectClass:

class PageObject:

def __init__(self, driver, xpathLocator):
    self.driver = driver
    self.locator = xpathLocator
    self.wait = WebDriverWait(self.driver, 100)

def waitElementToBePresent(self, timeout=10):
    WebDriverWait(self.driver, timeout).until(
        EC.visibility_of_element_located((By.XPATH, self.locator)))

def elementIsPresent(self):
    return EC.visibility_of_element_located((By.XPATH, self.locator))

def alertIsPresent(self, timeout=10):
    WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

def alertDismiss(self):
    alert = self.driver.switch_to_alert()
    alert.dismiss()

Can you try creating object in your other class like `pageObject = PageObject()` and then `pageObject.alertDismiss()` — Helping Hands, Feb 05 '20 at 13:04
If I add this object in my first class, I have some caution: `Parameter 'driver' unfilled Parameter 'xpathLocator' unfilled` But I do not use it. — Igor-Potapov, Feb 05 '20 at 13:13

No need to use two functions, EC.alert_is_present() will return the alert

def alertIsPresent(self, timeout=10):
    return WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

You also need to call it from class instance, not type

PageObject(driver).alertIsPresent().dismiss()

You havn't mentioned the version information of the Selenium's python client.

However, as per the the current implementation and documentation:

switch_to

SwitchTo: an object containing all options to switch focus into

Usage: driver.switch_to.alert

So, effectively, you need to replace the line:

alert = self.driver.switch_to_alert()

With:

alert = self.driver.switch_to.alert

hm... If I remove "self" I received message: `Unresolved reference 'self' ` – Igor-Potapov Feb 05 '20 at 13:53
@Igor-Potapov No confusion about `self`, I missed the `driver`, corrected it. let me know the status – undetected Selenium Feb 05 '20 at 13:54
