Handling Java Alerts using Selenium Webdriver

Understanding Java Alerts 🤔

Java Alerts are used to convey important information, warnings, or prompt user interaction. They can appear as simple informational messages, confirmations, or input prompts.

Types of Java Alerts:

Alerts: Simple notifications that require acknowledgment.
Confirmations: Alerts with options to confirm or cancel.
Prompts: Alerts that prompt the user to enter input.

Selenium Commands for Java Alerts 🕹

Alert Interface:

Selenium provides the Alert interface to interact with Java Alerts. Here are some essential methods:

Switch to Alert:

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

Accept Alert (OK/Yes):
```
  alert.accept();
```
Dismiss Alert (Cancel/No):
```
  alert.dismiss();
```
Get Alert Text:
```
  String alertText = alert.getText();
```
Enter Text in Prompt:
```
  alert.sendKeys("YourInput");
```

Handling Different Alert Types 🔄

Simple Alerts: Simple alerts require only acknowledgment. Use accept() to close them.
```
 Alert simpleAlert = driver.switchTo().alert();
 simpleAlert.accept();
```

Confirm Alerts: Confirm alerts have options to confirm or cancel. Use accept() for confirmation and dismiss() for cancellation.

 Alert confirmAlert = driver.switchTo().alert();
 confirmAlert.accept(); // Confirm
 // OR
 confirmAlert.dismiss(); // Cancel

Prompt Alerts: Prompt alerts prompt the user to enter input. Use sendKeys() to enter text and accept() to confirm.

 Alert promptAlert = driver.switchTo().alert();
 promptAlert.sendKeys("YourInput");
 promptAlert.accept();

Example: Handling a Login Alert 🌐

Consider a scenario where a website prompts an alert upon incorrect login credentials. You can handle it like this:

// Locate login elements and trigger login attempt
driver.findElement(By.id("username")).sendKeys("yourUsername");
driver.findElement(By.id("password")).sendKeys("wrongPassword");
driver.findElement(By.id("loginBtn")).click();

// Handle alert
Alert loginAlert = driver.switchTo().alert();
String alertText = loginAlert.getText();
System.out.println("Alert Text: " + alertText);
loginAlert.accept();

Conclusion 🎓

Mastering Java Alerts is essential for robust Selenium test automation. With the Alert interface, you can seamlessly handle alerts of different types, ensuring your automated tests handle pop-ups gracefully. Happy testing! 🚀🚦
