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:

1. Alerts: Simple notifications that require acknowledgment.

2. Confirmations: Alerts with options to confirm or cancel.

3. 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 🔄

1. Simple Alerts: Simple alerts require only acknowledgment. Use accept() to close them.

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

2. 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
   

3. 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! 🚀🚦
