Handling Alert popup:

*** FAQ : How can you handle alert  popup window ?

Handling alert popups in Selenium WebDriver involves several methods and considerations, especially when dealing with both regular and confirmation-type alerts. Here's a detailed approach to handling them:

Types of Alert Popups:

1.     Regular Alerts (Simple Alerts):

• These alerts display a message but do not require user input (e.g., informational messages).

2.     Confirmation Alerts (Prompt Alerts):

• These alerts require the user to take an action, such as confirming or cancelling an operation.

 

 

 After saving data in customer/ employee/  order page-  it displays some  alert popup window

saying "customer ='Ram' is created succefullly"

            Order No.123 created succefully

 

Note : 

-----

1. Alert popup window -- cannot be inspected

 We cannot inspect any element in alert window

 

2. Some alert popup window ele - we can inspect

Methods to Handle Alerts in Selenium WebDriver:

1. Switch to Alert:

• Use switchTo().alert() method to switch the driver's focus to the alert.

java

Alert alert = driver.switchTo().alert();

2. Get Text from Alert:

• Retrieve the text displayed in the alert using getText() method.

java

String alertText = alert.getText();

3. Accepting (Clicking OK) or Dismissing (Clicking Cancel) Alerts:

• Use accept() method to click on the 'OK' or 'Yes' button.
• Use dismiss() method to click on the 'Cancel' or 'No' button.

java

alert.accept(); // To accept the alert (click on 'OK' or 'Yes')

alert.dismiss(); // To dismiss the alert (click on 'Cancel' or 'No')

4. Send Data to Confirmation Alerts (Prompt Alerts):

• For confirmation alerts that expect user input, use sendKeys() method before accepting or dismissing.

java

alert.sendKeys("Text to send"); // Send text to prompt alert

Revision:

--------

  

   Alert al=  driver.switchto().alert();

   get popup msg --> 

   send data --> 

   accept() --> 

   dismiss()--> 

  no ele -->

  no alert -->  if we try switch to alert -->

Can we inspect alert popup window -->

                        // HW   Click 'Display Multiple alert msg' btn  to get alert popup window

 

                        System.out.println("Click 'Display Multiple alert msg'  to get alert popup window");

                        // HW get the msg from alert window

//o/p:Please enter Employee name

 

//HW click Ok button

 

//HW get popup msg  i.e Order No : 101 created successfully
