Double click in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

What is a double click in Selenium WebDriver?

A double click is a user action where the mouse button is clicked twice quickly on an element. In Selenium WebDriver, it simulates this action to trigger events that require two clicks.

beginner

Which Selenium class is used to perform a double click?

The <strong>Actions</strong> class is used to perform complex user interactions like double click in Selenium WebDriver.

beginner

Write the Java code snippet to double click on a WebElement named element.

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

beginner

Why do we use perform() after doubleClick() in Selenium?

The perform() method executes the action built by the Actions class. Without it, the double click will not happen.

intermediate

What could happen if you try to double click on a non-interactive element?

The double click might have no effect or cause an error if the element does not support double click events or is not visible/clickable.

Which Selenium class do you use to perform a double click?

A WebElement

B Actions

C WebDriver

D JavascriptExecutor

The Actions class is designed for complex user interactions like double click.

What method must be called to execute a double click action in Selenium?

A run()

B execute()

C perform()

D start()

The perform() method triggers the built action sequence.

What happens if you forget to call perform() after doubleClick()?

A No action is performed

B Element is clicked once

C Test fails immediately

D Double click happens automatically

Without perform(), the action is not executed.

Which of these is a valid way to double click on an element named el?

A actions.doubleClick(el).perform();

B actions.doubleClick(el);

C actions.click(el).click(el).perform();

D actions.doubleClick().perform(el);

The correct syntax is doubleClick(element).perform().

If an element is not visible, what will happen when you try to double click it?

A Test passes without action

B Double click succeeds silently

C Element becomes visible automatically

D Selenium throws an exception

Selenium throws an exception if the element is not visible or clickable.

Explain how to perform a double click on a web element using Selenium WebDriver in Java.

Think about the sequence of method calls needed.

What are common issues you might face when using double click in Selenium and how to avoid them?

Consider element state and action execution.

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
