Keyboard actions (keyDown, keyUp) in Selenium Java - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

intermediate

What is the output of this Selenium Java code snippet?

Consider the following Selenium Java code that performs keyboard actions on a web element. What will be the final text input in the field after execution?

Selenium Java

WebElement input = driver.findElement(By.id("username"));
Actions actions = new Actions(driver);
actions.keyDown(Keys.SHIFT).sendKeys(input, "hello").keyUp(Keys.SHIFT).perform();

A "hello"

B "HELLO"

C "Hello"

D "hELLO"

💡 Hint

Remember what holding down the SHIFT key does to letters when typing.

Holding down the SHIFT key while sending keys converts letters to uppercase. Since keyDown(Keys.SHIFT) is active during sendKeys, all letters are uppercase.

❓ assertion

intermediate

Which assertion correctly verifies that SHIFT key was released after typing?

You want to assert that after performing keyDown(Keys.SHIFT) and sendKeys, the SHIFT key is no longer pressed. Which assertion is valid in Selenium Java?

Selenium Java

Actions actions = new Actions(driver);
actions.keyDown(Keys.SHIFT).sendKeys("test").keyUp(Keys.SHIFT).perform();

A assertFalse(actions.isShiftDown());

B assertTrue(actions.isShiftDown());

C assertEquals(false, actions.isShiftDown());

D assertNull(actions.getShiftState());

💡 Hint

Check if the SHIFT key is pressed or not after keyUp.

After keyUp(Keys.SHIFT), the SHIFT key should not be pressed, so isShiftDown() should return false.

🔧 Debug

Why does this Selenium Java code throw an exception?

Examine the code below. It throws an exception at runtime. What is the cause?

Selenium Java

WebElement input = driver.findElement(By.id("inputField"));
Actions actions = new Actions(driver);
actions.keyDown(Keys.CONTROL).sendKeys("a").perform();
actions.keyUp(Keys.CONTROL).perform();

A keyUp(Keys.CONTROL) must be called before perform()

B sendKeys("a") is invalid without keyUp

C keyDown and keyUp must be chained in the same Actions before perform()

D input element is not focused before sending keys

💡 Hint

Check how keyDown and keyUp are chained in Actions.

keyDown and keyUp should be chained in the same Actions sequence before calling perform(). Calling perform() after keyDown and then again after keyUp breaks the sequence and causes an exception.

🧠 Conceptual

advanced

What is the main difference between keyDown and sendKeys in Selenium Actions?

Choose the best explanation of how keyDown and sendKeys differ in Selenium Actions.

A keyDown presses and holds a key, sendKeys types characters or keys

B keyDown types characters, sendKeys presses and holds keys

C keyDown releases a key, sendKeys presses a key

D keyDown and sendKeys perform the same action

💡 Hint

Think about holding keys vs typing characters.

keyDown simulates pressing and holding a key (like SHIFT), while sendKeys sends characters or key presses to the element.

❓ framework

In a Selenium Java test framework, how to best implement a reusable method for typing uppercase text using keyboard actions?

You want a reusable method that types a given string in uppercase by holding SHIFT using Selenium Actions. Which method implementation is correct and efficient?

Selenium Java

public void typeUppercase(WebElement element, String text) {
    Actions actions = new Actions(driver);
    // fill in
}

A actions.keyDown(Keys.SHIFT).sendKeys(element, text.toUpperCase()).keyUp(Keys.SHIFT).perform();

B actions.keyDown(Keys.SHIFT).sendKeys(text).keyUp(Keys.SHIFT).perform();

C actions.sendKeys(element, text.toUpperCase()).perform();

D actions.keyDown(Keys.SHIFT).sendKeys(element, text).keyUp(Keys.SHIFT).perform();

💡 Hint

SHIFT key changes letter case during typing; no need to convert string manually.

Holding SHIFT while sending keys types uppercase letters automatically, so sending the original text with SHIFT held is best. Option D sends already uppercase text with SHIFT, resulting in wrong characters.
