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.

❓ framework

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.
