How to Handle Alerts & Select with Selenium in Python

While Testing web application, We generally encounter Alert box, Select drop downs. Let’s see How we can handle them with selenium web driver in python.

Generally, JavaScript popups are generated by the web application and hence they can be easily controlled by the browser.

Case1: Handling the Alert/Pops:

Create a Selenium Project and in the test Method write the below code to handle the Alert box/Pop. Just get the element using the
”find element by xpath method” and use

alertObj = driver.switch_to.alert
alertObj.accept()
# To dismiss
alertObj.dismiss()

Case2: Handling the (Select)DropDown:

Create a Selenium Project and in the test Method write the below code to handle the select dropdown. Just get the element using the
”find element by xpath or id method” and use

def test_waitForCheckOutPhotosButton(self):
dropDownId= "wsite-com-product-option-Quantity"
dropDownElement = WebDriverWait(driver, 10).
until(lambda driver : driver.find_element_by_id(dropDownId))
Select(dropDownElement).select_by_value("2")''

Case3: Handling the Window Frame:

Lets assume that, When you click on button1(id=’button1’) on the main window a new window pop opens and you have switch to that window and click the button(id=’window1_button2’) on it.

def test_waitForCheckOutPhotosButton(self):
button1 = WebDriverWait(driver,10)
.until(lambda driver: driver.find_element_by_id("button1"))

#Getting the Main Window Handle
mainHanlde = driver.window_handles

button1.click()

#Getting all windows Main and Window 1 handle in All Handle
allHandle = driver.window_handles

for c in allHandle:
if c !=mainHanlde[0]:
driver.switch_to_window(c)
break

button2= button1 = WebDriverWait(driver,10)
.until(lambda driver: driver.find_element_by_id("window1_button2"))
