Double click in Selenium Java - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

intermediate

What is the result of this Selenium double click code?

Given the following Selenium Java code snippet, what will be the output after executing the double click action on the button?

Selenium Java

WebElement button = driver.findElement(By.id("btnDoubleClick"));
Actions actions = new Actions(driver);
actions.doubleClick(button).perform();
String message = driver.findElement(By.id("message")).getText();
System.out.println(message);

A Throws ElementNotInteractableException when performing double click

B The message element text remains empty

C Throws NoSuchElementException for the button element

D The message element text changes to "Double click successful!"

💡 Hint

Consider what happens when doubleClick() is performed on a visible, enabled button.

The doubleClick() action triggers the button's double click event, which updates the message text to "Double click successful!". If the button is present and interactable, no exceptions occur.

❓ locator

intermediate

Which locator is best for double clicking a button with text 'Submit'?

You want to double click a button that displays the text 'Submit'. Which locator is the most reliable and efficient for this purpose?

A By.xpath("//button[text()='Submit']")

B By.cssSelector("button:contains('Submit')")

C By.id("submitBtn")

D By.className("btn-submit")

💡 Hint

Consider which locator directly matches the button text exactly.

Option A uses XPath to find a button element with exact text 'Submit', which is precise. Option A is invalid because CSS does not support :contains. Options C and D depend on attributes that may not exist or be unique.

❓ assertion

advanced

Which assertion correctly verifies double click effect?

After performing a double click on an element, you want to assert that a confirmation message is displayed with text 'Action completed'. Which assertion is correct in Java with TestNG?

Selenium Java

String actualMessage = driver.findElement(By.id("confirmMsg")).getText();

A Assert.assertNotNull(actualMessage);

B Assert.assertTrue(actualMessage.contains("Action completed"));

C Assert.assertEquals(actualMessage, "Action completed");

D Assert.assertFalse(actualMessage.isEmpty());

💡 Hint

Which assertion exactly matches the expected message text?

Option C checks exact equality, ensuring the message is exactly 'Action completed'. Other options are less strict or only check presence, not exact match.

🔧 Debug

Why does this double click code throw ElementNotInteractableException?

Review the code below and select the reason why ElementNotInteractableException is thrown when performing double click.

Selenium Java

WebElement hiddenButton = driver.findElement(By.id("hiddenBtn"));
Actions actions = new Actions(driver);
actions.doubleClick(hiddenButton).perform();

A The button is hidden or not visible on the page

B The driver instance is null

C The Actions class is not properly imported

D The locator used is incorrect and finds no element

💡 Hint

ElementNotInteractableException occurs when element is present but cannot be interacted with.

If the element is hidden or not visible, Selenium cannot interact with it, causing ElementNotInteractableException. Incorrect locator would cause NoSuchElementException instead.

How to implement a reusable double click method in Selenium Java framework?

You want to create a reusable method in your Selenium Java framework to perform double click on any WebElement. Which method implementation is correct and follows best practices?

Selenium Java

public void doubleClickElement(WebDriver driver, WebElement element) {
    // method body
}

A

element.click();
element.click();

B

Actions actions = new Actions(driver);
actions.doubleClick(element).perform();

C

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].dblclick();", element);

D

driver.findElement(By.id(element.getAttribute("id"))).click();
driver.findElement(By.id(element.getAttribute("id"))).click();

💡 Hint

Consider the standard Selenium way to perform double click using Actions class.

Option B uses Actions class doubleClick method which is the recommended way. Option B simulates double click by two clicks but may not trigger double click event. Option B uses JavaScript but dblclick() is not a standard JS method. Option B repeats clicks by locating element again, inefficient and unreliable.

Practice

1. What is the purpose of the doubleClick() method in Selenium WebDriver's Actions class?

easy

A. To perform a double-click action on a web element

B. To click and hold a web element

C. To right-click on a web element

D. To drag and drop a web element

Solution

1. Step 1: Understand the Actions class role

   The Actions class in Selenium is used to build complex user interactions like mouse and keyboard events.

2. Step 2: Identify the doubleClick() method function

   The doubleClick() method specifically performs a double-click on the targeted web element.

3. Final Answer:

   To perform a double-click action on a web element -> Option A

4. Quick Check:

   doubleClick() = double-click action [OK]

Hint: Double click means two quick clicks on the same element [OK]

Common Mistakes:

• Confusing doubleClick() with clickAndHold()
• Thinking doubleClick() performs right-click
• Assuming doubleClick() drags elements

2. Which of the following is the correct syntax to perform a double click on a web element using Selenium WebDriver in Java?

easy

A. new Actions(driver).doubleClick(element).perform();

B. driver.doubleClick(element);

C. Actions.doubleClick(element).perform();

D. driver.actions().doubleClick(element).execute();

Solution

1. Step 1: Recall the correct way to use Actions class

   In Selenium Java, you create an Actions object with the driver, then chain the doubleClick() method with the target element, and call perform() to execute.

2. Step 2: Check each option's syntax

   new Actions(driver).doubleClick(element).perform(); matches the correct syntax: new Actions(driver).doubleClick(element).perform();. Others are invalid or incorrect method calls.

3. Final Answer:

   new Actions(driver).doubleClick(element).perform(); -> Option A

4. Quick Check:

   Actions object + doubleClick + perform() = correct syntax [OK]

Hint: Always end Actions chain with perform() to execute [OK]

Common Mistakes:

• Calling doubleClick directly on driver
• Missing perform() at the end
• Using incorrect method names or chaining

3. What will be the output of the following Selenium Java code snippet if the element is present and clickable?

WebElement element = driver.findElement(By.id("btn"));
new Actions(driver).doubleClick(element).perform();
System.out.println("Double click performed");

medium

A. Syntax error, code will not compile

B. No output, code throws NoSuchElementException

C. No output, code throws ElementNotInteractableException

D. Double click performed

Solution

1. Step 1: Analyze element presence and action

   The element is found by ID and assumed present and clickable, so doubleClick() will execute without exceptions.

2. Step 2: Check the print statement execution

   After performing the double click, the print statement will execute and output the string.

3. Final Answer:

   Double click performed -> Option D

4. Quick Check:

   Element found + doubleClick success = print output [OK]

Hint: If element exists and is clickable, actions run and print executes [OK]

Common Mistakes:

• Assuming exceptions without element issues
• Thinking doubleClick blocks further code
• Confusing compile errors with runtime behavior

4. Identify the error in the following Selenium Java code snippet that tries to double click an element:

Actions action = new Actions(driver);
action.doubleClick();
action.perform();

medium

A. perform() should be called before doubleClick()

B. Actions object should be static

C. Missing target element in doubleClick() method

D. doubleClick() method does not exist in Actions class

Solution

1. Step 1: Check doubleClick() method usage

   The doubleClick() method requires a target WebElement to act on. Calling it without an element is incorrect.

2. Step 2: Validate method call order and existence

   Calling perform() after building the action is correct. The method exists and Actions object need not be static.

3. Final Answer:

   Missing target element in doubleClick() method -> Option C

4. Quick Check:

   doubleClick() needs element argument [OK]

Hint: Always pass the element to doubleClick() [OK]

Common Mistakes:

• Calling doubleClick() without element
• Wrong order of perform() call
• Thinking Actions must be static

5. You want to double click on a button with id submitBtn and then verify if a confirmation message with id confirmMsg appears. Which of the following code snippets correctly performs this and asserts the message is displayed?

hard

A. WebElement btn = driver.findElement(By.id("submitBtn"));
new Actions(driver).click(btn).click(btn).perform();
assertTrue(driver.findElement(By.id("confirmMsg")).isDisplayed());

B. WebElement btn = driver.findElement(By.id("submitBtn"));
new Actions(driver).doubleClick(btn).perform();
WebElement msg = driver.findElement(By.id("confirmMsg"));
assertTrue(msg.isDisplayed());

C. Actions action = new Actions(driver);
action.doubleClick();
action.perform();
assertTrue(driver.findElement(By.id("confirmMsg")).isDisplayed());

D. driver.findElement(By.id("submitBtn")).doubleClick();
assertTrue(driver.findElement(By.id("confirmMsg")).isDisplayed());

Solution

1. Step 1: Perform double click on the button element

   WebElement btn = driver.findElement(By.id("submitBtn")); new Actions(driver).doubleClick(btn).perform(); WebElement msg = driver.findElement(By.id("confirmMsg")); assertTrue(msg.isDisplayed()); correctly finds the button element and uses new Actions(driver).doubleClick(btn).perform(); to double click it.

2. Step 2: Verify confirmation message is displayed

   WebElement btn = driver.findElement(By.id("submitBtn")); new Actions(driver).doubleClick(btn).perform(); WebElement msg = driver.findElement(By.id("confirmMsg")); assertTrue(msg.isDisplayed()); then finds the confirmation message element and asserts it is displayed using assertTrue(msg.isDisplayed());.

3. Final Answer:

   Correct double click and assertion sequence -> Option B

4. Quick Check:

   Find element + doubleClick + assert displayed = correct [OK]

Hint: Use Actions with element, then assert message visibility [OK]

Common Mistakes:

• Using click twice instead of doubleClick()
• Calling doubleClick() without element
• Trying to doubleClick() directly on driver
