How to handle Alert using selenium

Generally alert pop up are of three types:

1. Alert pop up with OK button

2. Alert pop up with OK and Cancel button

3. Alert pop up with OK , Cancel button and Text field to enter values.

To deal with alert pop up selenium comes with simple method Alert();

In the first case where we only have OK button below mentioned code snippet will be helpfull.

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

alert.accept();

Above code snippet will switch the control to alert and it will accept it.

In the second case where we have cancel button as well, code snippet will be:

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

alert.accept() — To accept the alert

alert.dismiss() — To dismiss the alert

In the last case where we are supposed to enter some value and click either OK or Cancel , code snippet will be:

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

alert.sendKeys(“value to enter”);

alert.accept(); or alert.dismiss();
