Practice - 5 Tasks

1fill in blank

easy

Complete the code to get the value of the "href" attribute from the link element.

Selenium Java

String link = driver.findElement(By.id("homeLink")).[1]("href");

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

AgetAttribute

BgetText

CgetCssValue

DgetTagName

💡 Hint

Common Mistakes

Using getText() instead of getAttribute() to get attribute values.

Using getCssValue() which is for CSS properties, not attributes.

The getAttribute method retrieves the value of the specified attribute from the web element.

Complete the code to set the "value" attribute of an input element using JavaScript executor.

Selenium Java

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].[1] = 'test';", element);

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

AsetValue

BsetAttribute

Cvalue

💡 Hint

Common Mistakes

Trying to call setAttribute as a property.

Using innerText which changes visible text, not input value.

To set the value attribute via JavaScript, assign directly to the value property of the element.

3fill in blank

hard

Fix the error in the code to correctly get the "class" attribute of a web element.

Selenium Java

String className = element.[1]("class");

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

AgetAttribute

BgetText

CgetClass

DgetCssValue

Attempts:

💡 Hint

Common Mistakes

Using getClass() which is a Java method, not Selenium WebElement method.

Passing "className" instead of "class" to getAttribute.

The correct method to get the "class" attribute is getAttribute("class"). The option "className" is not an attribute name here.

4fill in blank

hard

Fill both blanks to set the "placeholder" attribute of an input element using JavaScript executor.

Selenium Java

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].[1]('[2]', 'Enter name');", element);

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

AsetAttribute

BgetAttribute

Cplaceholder

Dvalue

💡 Hint

Common Mistakes

Using getAttribute instead of setAttribute to set values.

Passing wrong attribute names like "value" instead of "placeholder".

Use setAttribute method to set the attribute, and specify the attribute name "placeholder".

5fill in blank

hard

Fill all three blanks to create a map of element IDs to their "title" attribute values for elements in the list.

Selenium Java

Map<String, String> titles = elements.stream()
  .collect(Collectors.toMap(e -> e.[1]("id"), e -> e.[2]("[3]")));

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

AgetId

BgetAttribute

Ctitle

DgetText

Attempts:

3 left

💡 Hint

Common Mistakes

Using getText() instead of getAttribute("title") for attribute values.

Using wrong method names like getId() which is not standard in Selenium.

Use getAttribute("id") to get element IDs, getAttribute("title") to get the title attribute.

Practice

1. What is the primary method to get an attribute value of a web element in Selenium Java?

easy

A. Using driver.getAttribute("attributeName")

B. Using element.setAttribute("attributeName")

C. Using element.getText()

D. Using element.getAttribute("attributeName")

Solution

1. Step 1: Understand the method to retrieve attribute

   In Selenium Java, getAttribute is used on a WebElement to fetch the value of an attribute.

2. Step 2: Identify correct usage

   The syntax is element.getAttribute("attributeName"), which returns the attribute's value as a string.

3. Final Answer:

   Using element.getAttribute("attributeName") -> Option D

4. Quick Check:

   Get attribute = element.getAttribute("attributeName") [OK]

Hint: Remember: getAttribute reads, setAttribute does not exist directly [OK]

Common Mistakes:

• Confusing getAttribute with setAttribute
• Trying to use driver.getAttribute instead of element.getAttribute
• Using getText() to get attribute values

2. Which of the following is the correct way to set an attribute value of a web element in Selenium Java?

easy

A. Using JavaScriptExecutor to run arguments[0].setAttribute('value', 'newValue')

B. element.setAttribute("value", "newValue")

C. element.getAttribute("value") = "newValue"

D. element.setValue("newValue")

Solution

1. Step 1: Understand Selenium's limitation on setting attributes

   Selenium WebElement does not have a direct setAttribute method.

2. Step 2: Use JavaScriptExecutor to set attribute

   We use JavaScriptExecutor to run JavaScript code that sets the attribute, e.g., arguments[0].setAttribute('value', 'newValue').

3. Final Answer:

   Using JavaScriptExecutor to run arguments[0].setAttribute('value', 'newValue') -> Option A

4. Quick Check:

   Set attribute = JavaScriptExecutor + setAttribute() [OK]

Hint: Set attributes via JavaScriptExecutor, not WebElement methods [OK]

Common Mistakes:

• Trying to call setAttribute directly on WebElement
• Assigning value to getAttribute() result
• Using non-existent setValue() method

3. Consider the following Selenium Java code snippet:

WebElement input = driver.findElement(By.id("username"));
String value = input.getAttribute("value");
System.out.println(value);

If the input field has value="testUser", what will be printed?

medium

A. testUser

B. null

C. value

D. username

Solution

1. Step 1: Identify the attribute being fetched

   The code calls getAttribute("value") on the input element, which returns the current value attribute.

2. Step 2: Match attribute value with output

   The input field has value="testUser", so value variable will be "testUser" and printed.

3. Final Answer:

   testUser -> Option A

4. Quick Check:

   getAttribute("value") = "testUser" [OK]

Hint: getAttribute returns actual attribute value, not element text [OK]

Common Mistakes:

• Confusing getAttribute("value") with getText()
• Expecting attribute name instead of value
• Assuming null if attribute exists

4. You want to set the attribute placeholder of an input element to "Enter name" using Selenium Java. Which code snippet fixes the error below?

// Current code
WebElement input = driver.findElement(By.id("name"));
input.setAttribute("placeholder", "Enter name"); // Error: cannot find symbol

medium

A. Use input.sendKeys("Enter name")

B. Replace with input.getAttribute("placeholder") = "Enter name";

C. Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('placeholder', 'Enter name')", input);

D. Use input.setValue("Enter name")

Solution

1. Step 1: Identify why error occurs

   WebElement does not have a setAttribute method, so calling it causes a compile error.

2. Step 2: Use JavaScriptExecutor to set attribute

   JavaScriptExecutor can run JavaScript to set attributes on elements, e.g., arguments[0].setAttribute('placeholder', 'Enter name').

3. Final Answer:

   Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('placeholder', 'Enter name')", input); -> Option C

4. Quick Check:

   Set attribute via JSExecutor = Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('placeholder', 'Enter name')", input); [OK]

Hint: Set attributes only via JavaScriptExecutor, not WebElement methods [OK]

Common Mistakes:

• Trying to assign value to getAttribute()
• Using non-existent setValue() method
• Using sendKeys() which inputs text, not sets attribute

5. You want to verify if a checkbox is checked by reading its checked attribute using Selenium Java. Which approach correctly checks this and sets it checked if not already?

WebElement checkbox = driver.findElement(By.id("agree"));
String checked = checkbox.getAttribute("checked");
if (checked == null) {
    // Set checked attribute here
}

hard

A. Use checkbox.setAttribute("checked", "true")

B. Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('checked', 'true')", checkbox);

C. Use checkbox.click() to check the box

D. Use checkbox.getAttribute("checked") = "true"

Solution

1. Step 1: Check if checkbox is checked by reading 'checked' attribute

   If getAttribute("checked") returns null, checkbox is not checked.

2. Step 2: Set 'checked' attribute using JavaScriptExecutor

   Since WebElement has no setAttribute, use JavaScriptExecutor to set checked attribute to "true".

3. Final Answer:

   Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('checked', 'true')", checkbox); -> Option B

4. Quick Check:

   Set attribute via JSExecutor = Use JavaScriptExecutor: js.executeScript("arguments[0].setAttribute('checked', 'true')", checkbox); [OK]

Hint: Check attribute with getAttribute; set with JSExecutor [OK]

Common Mistakes:

• Trying to call setAttribute directly on WebElement
• Using assignment on getAttribute() result
• Using click() which toggles but does not set attribute directly
