Handling Alerts & Popups in Selenium🚨

Alerts, also known as pop-ups or dialog boxes, are common elements encountered during web testing. Selenium WebDriver provides a robust set of commands to handle these alerts effectively. In this guide, we'll explore the ins and outs of handling Java Alerts using Selenium WebDriver.

Understanding Alerts 🤔

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

Types of Alerts:

1. Alerts: Simple notifications that require acknowledgement.

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

3. Prompts: Alerts that prompt the user to enter input.

Selenium Commands for Alerts using Java 🕹️

Alert Interface:

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

1. Switch to Alert:

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

2. Accept Alert (OK/Yes):

    alert.accept();
   

3. Dismiss Alert (Cancel/No):

    alert.dismiss();
   

4. Get Alert Text:

    String alertText = alert.getText();
   

5. Enter Text in Prompt:

    alert.sendKeys("YourInput");
   

Handling Different Alert Types 🔄

1. Simple Alerts:

Simple alerts require only acknowledgement. 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 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! 🚀🚦
