💡 Hint

Common Mistakes

Forgetting parentheses after alert()

Using switchTo.alert without parentheses

In Selenium Java, to switch to an alert, you use driver.switchTo().alert() with parentheses to get the Alert object.

2fill in blank

Complete the code to accept the alert.

Selenium Java

alert.[1]();

Drag options to blanks, or click blank then click option'

Caccept

💡 Hint

Common Mistakes

Using dismiss() instead of accept() to accept the alert

Trying to use close() which is not valid for alerts

To accept an alert in Selenium Java, you call the accept() method on the Alert object.

3fill in blank

hard

Fix the error in the code to dismiss the alert.

Selenium Java

alert.[1]();

Drag options to blanks, or click blank then click option'

Adismiss

Bdismiss()

Caccept

Dclose

💡 Hint

Common Mistakes

Including parentheses inside the blank token

Using accept() instead of dismiss() to cancel the alert

The dismiss() method is called without parentheses in the code, but in Java it must be called with parentheses. The correct code is alert.dismiss(); so the blank must be 'dismiss'.

4fill in blank

hard

Fill both blanks to get alert text and accept it.

Selenium Java

String text = alert.[1]();
alert.[2]();

Drag options to blanks, or click blank then click option'

AgetText

Baccept

Cdismiss

DsendKeys

💡 Hint

Common Mistakes

Using dismiss() instead of accept() to accept the alert

Forgetting to call getText() as a method

To get the alert text, use getText(). To accept the alert, use accept(). Both are methods called with parentheses.

5fill in blank

hard

Fill all three blanks to send text to prompt alert, get text, and accept it.

Selenium Java

alert.[1]("Hello");
String msg = alert.[2]();
alert.[3]();

Drag options to blanks, or click blank then click option'

AsendKeys

BgetText

Caccept

Ddismiss

💡 Hint

Common Mistakes

Using dismiss() instead of accept() to confirm the alert

Forgetting parentheses on method calls

To send text to a prompt alert, use sendKeys("text"). To get the alert text, use getText(). To accept the alert, use accept(). All are methods called with parentheses.

Practice

1. What does the accept() method do when called on a JavaScript alert in Selenium?

easy

A. Clicks the OK button on the alert

B. Clicks the Cancel button on the alert

C. Closes the browser window

D. Throws an exception without interacting

Solution

1. Step 1: Understand alert interaction methods

   The accept() method is used to click the OK button on an alert popup.

2. Step 2: Differentiate from dismiss()

   The dismiss() method clicks Cancel, so accept() must click OK.

3. Final Answer:

   Clicks the OK button on the alert -> Option A

4. Quick Check:

   accept() = OK click [OK]

Hint: accept() clicks OK, dismiss() clicks Cancel [OK]

Common Mistakes:

• Confusing accept() with dismiss()
• Thinking accept() closes the browser
• Assuming accept() throws an exception

2. Which of the following is the correct syntax to switch to an alert and dismiss it in Selenium Java?

easy

A. driver.switchTo().alert().dismiss();

B. driver.switchTo().alert().cancel();

C. driver.switchTo().alert().close();

D. driver.switchTo().alert().accept();

Solution

1. Step 1: Identify the method to dismiss alert

   The method to click Cancel on an alert is dismiss().

2. Step 2: Confirm correct syntax for switching and dismissing

   The correct chain is driver.switchTo().alert().dismiss(); to dismiss the alert.

3. Final Answer:

   driver.switchTo().alert().dismiss(); -> Option A

4. Quick Check:

   dismiss() = Cancel click [OK]

Hint: Use dismiss() to cancel alerts, accept() to confirm [OK]

Common Mistakes:

• Using accept() instead of dismiss() to cancel
• Using non-existent methods like close() or cancel()
• Missing switchTo().alert() before calling dismiss()

3. Given the following code snippet, what will be printed if the alert is accepted?

driver.switchTo().alert().accept();
System.out.println("Alert handled successfully");

medium

A. UnhandledAlertException

B. Alert handled successfully

C. No output

D. Alert not found error

Solution

1. Step 1: Understand alert acceptance effect

   Calling accept() closes the alert, allowing the next line to execute.

2. Step 2: Check output after alert handling

   Since alert is accepted, System.out.println runs and prints the message.

3. Final Answer:

   Alert handled successfully -> Option B

4. Quick Check:

   accept() closes alert, next line prints [OK]

Hint: accept() lets code continue, so print runs [OK]

Common Mistakes:

• Expecting exception after accept()
• Thinking alert blocks print statement
• Confusing accept() with dismiss() effect

4. Identify the error in this Selenium Java code snippet that tries to dismiss an alert:

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

medium

A. alert.dismiss() should be alert.cancel()

B. Calling accept() before dismiss() causes an exception

C. Missing driver.switchTo() before alert()

D. Cannot call dismiss() after accept() on the same alert instance

Solution

1. Step 1: Understand alert lifecycle after accept()

   Once accept() is called, the alert is closed and no longer available.

2. Step 2: Calling dismiss() after accept() is invalid

   Trying to dismiss the same alert after accepting it causes an error because alert is gone.

3. Final Answer:

   Cannot call dismiss() after accept() on the same alert instance -> Option D

4. Quick Check:

   accept() closes alert, no dismiss() after [OK]

Hint: Alert closes after accept(), can't dismiss same alert [OK]

Common Mistakes:

• Calling dismiss() after accept() on same alert
• Assuming alert stays open after accept()
• Using non-existent cancel() method

5. You want to write a Selenium Java test that clicks Cancel on a confirmation alert only if the alert text contains the word "Delete". Which code snippet correctly implements this?

hard

A. Alert alert = driver.switchTo().alert();
if (alert.getText() == "Delete") {
alert.accept();
} else {
alert.dismiss();
}

B. Alert alert = driver.switchTo().alert();
alert.dismiss();
if (alert.getText().contains("Delete")) {
alert.accept();
}

C. Alert alert = driver.switchTo().alert();
if (alert.getText().contains("Delete")) {
alert.dismiss();
} else {
alert.accept();
}

D. Alert alert = driver.switchTo().alert();
alert.accept();
alert.dismiss();

Solution

1. Step 1: Check alert text for "Delete" substring

   Use alert.getText().contains("Delete") to detect if alert text includes "Delete".

2. Step 2: Dismiss alert if condition true, else accept

   If text contains "Delete", call dismiss() to click Cancel; otherwise, call accept().

3. Final Answer:

   Alert alert = driver.switchTo().alert(); if (alert.getText().contains("Delete")) { alert.dismiss(); } else { alert.accept(); } -> Option C

4. Quick Check:

   Use contains() and dismiss() for conditional cancel [OK]

Hint: Use getText().contains() before dismiss() or accept() [OK]

Common Mistakes:

• Using == instead of contains() for string check
• Calling dismiss() before checking alert text
• Calling accept() and dismiss() both without condition
