Radio button interactions in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to select a radio button by its ID.

Selenium Python

driver.find_element(By.ID, [1]).click()

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

A"checkbox1"

B"radio1"

C"submit"

D"button1"

💡 Hint

Common Mistakes

Using the wrong ID that does not belong to a radio button.

Trying to select a checkbox or button instead of a radio button.

The radio button with ID "radio1" is selected by using find_element(By.ID, "radio1") and then clicking it.

Complete the code to check if a radio button is selected.

Selenium Python

is_selected = driver.find_element(By.NAME, [1]).is_selected()

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

A"option"

B"submit"

C"radio"

D"gender"

💡 Hint

Common Mistakes

Using an incorrect name attribute that does not match the radio buttons.

Confusing the name attribute with the ID.

The radio buttons often share the same name attribute like "gender". We check if the radio button with name "gender" is selected.

Fix the error in the code to select a radio button using XPath.

Selenium Python

driver.find_element(By.XPATH, [1]).click()

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

A"//input[@type='radio' and @value='male']"

B"//button[@type='radio' and @value='male']"

C"//input[@type='checkbox' and @value='male']"

D"//input[@type='radio' and @name='female']"

💡 Hint

Common Mistakes

Using 'button' instead of 'input' in XPath.

Selecting checkboxes instead of radio buttons.

Using wrong attribute values.

The correct XPath selects an input element with type='radio' and value='male'. Other options select wrong elements or attributes.

4fill in blank

hard

Fill both blanks to create a function that selects a radio button by its value attribute.

Selenium Python

def select_radio_by_value(driver, value):
    radio = driver.find_element(By.CSS_SELECTOR, "input[type='radio'][value='" + [1] + "']")
    if not radio.[2]():
        radio.click()

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

Bis_selected

Cis_enabled

Dclick

💡 Hint

Common Mistakes

Using the wrong attribute name in the CSS selector.

Checking if the radio button is enabled instead of selected.

The function finds the radio button with the given value and clicks it only if it is not already selected using is_selected().

5fill in blank

hard

Fill all three blanks to create a test that verifies the correct radio button is selected after clicking.

Selenium Python

def test_radio_selection(driver):
    driver.get("http://example.com/radio")
    radio_buttons = driver.find_elements(By.NAME, [1])
    radio_buttons[[2]].click()
    assert radio_buttons[[3]].is_selected(), "Radio button not selected as expected"

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

A"gender"

B1

D0

💡 Hint

Common Mistakes

Using the wrong name attribute.

Clicking and asserting different indexes.

Forgetting that indexes start at 0.

The test opens the page, finds radio buttons by name "gender", clicks the second radio button (index 1), and asserts it is selected.

Practice

1. What does the is_selected() method do when used on a radio button element in Selenium?

easy

A. Checks if the radio button is currently selected

B. Clicks the radio button to select it

C. Returns the text label of the radio button

D. Clears the selection of the radio button

Solution

1. Step 1: Understand the purpose of is_selected()

   This method checks the current state of a radio button or checkbox to see if it is selected or not.

2. Step 2: Compare with other actions

   Unlike click() which changes the state, is_selected() only returns a boolean indicating selection status.

3. Final Answer:

   Checks if the radio button is currently selected -> Option A

4. Quick Check:

   Check selection status = C [OK]

Hint: Remember: is_selected() checks state, click() changes it [OK]

Common Mistakes:

• Confusing is_selected() with click()
• Expecting is_selected() to select the button
• Using is_selected() to get button text

2. Which of the following is the correct way to select a radio button with Selenium in Python?

easy

A. driver.find_element(By.ID, 'option1').choose()

B. driver.find_element(By.ID, 'option1').select()

C. driver.find_element(By.ID, 'option1').check()

D. driver.find_element(By.ID, 'option1').click()

Solution

1. Step 1: Identify the correct method to select a radio button

   In Selenium, click() is used to select radio buttons or checkboxes.

2. Step 2: Verify method names

   Methods like select(), check(), or choose() do not exist in Selenium WebDriver API.

3. Final Answer:

   driver.find_element(By.ID, 'option1').click() -> Option D

4. Quick Check:

   Use click() to select radio buttons = A [OK]

Hint: Use click() to select radio buttons, no select() method [OK]

Common Mistakes:

• Using non-existent methods like select()
• Trying to assign value instead of clicking
• Confusing with form select elements

3. Consider this code snippet:

radio1 = driver.find_element(By.ID, 'r1')
radio2 = driver.find_element(By.ID, 'r2')
radio1.click()
print(radio1.is_selected())
print(radio2.is_selected())

What will be the output if these are radio buttons in the same group?

medium

A. True\nFalse

B. False\nTrue

C. True\nTrue

D. False\nFalse

Solution

1. Step 1: Understand radio button group behavior

   Clicking one radio button selects it and deselects others in the same group.

2. Step 2: Analyze the code output

   After clicking radio1, radio1.is_selected() returns True, and radio2.is_selected() returns False.

3. Final Answer:

   True False -> Option A

4. Quick Check:

   One selected, others deselected = B [OK]

Hint: Only one radio button in group is selected at a time [OK]

Common Mistakes:

• Assuming both radio buttons can be selected
• Confusing is_selected() output order
• Ignoring group behavior of radio buttons

4. You wrote this code to select a radio button:

radio = driver.find_element(By.NAME, 'gender')
radio.click()

But it always selects the first radio button in the group, not the intended one. What is the likely problem?

medium

A. The click() method is incorrect for radio buttons

B. Using By.NAME returns multiple elements; need to specify which one

C. Radio buttons cannot be selected by Selenium

D. The radio button is disabled and cannot be clicked

Solution

1. Step 1: Understand how find_element(By.NAME) works

   This method returns the first matching element with the given name attribute.

2. Step 2: Identify the issue with multiple radio buttons sharing the same name

   Radio buttons in a group share the same name, so you must select the correct one by index or another attribute.

3. Final Answer:

   Using By.NAME returns multiple elements; need to specify which one -> Option B

4. Quick Check:

   By.NAME returns first element only = A [OK]

Hint: Use find_elements and index to pick correct radio button [OK]

Common Mistakes:

• Assuming By.NAME returns all elements
• Using click() incorrectly
• Ignoring radio button group naming

5. You want to write a test to verify that selecting one radio button deselects the others in the same group. Which code snippet correctly performs this check?

hard

A. radio_buttons = driver.find_elements(By.ID, 'color')
radio_buttons[0].click()
assert radio_buttons[1].is_selected()

B. radio_buttons = driver.find_element(By.NAME, 'color')
radio_buttons.click()
assert radio_buttons.is_selected()

C. radio_buttons = driver.find_elements(By.NAME, 'color')
radio_buttons[1].click()
assert radio_buttons[1].is_selected() and not radio_buttons[0].is_selected()

D. radio_buttons = driver.find_elements(By.CLASS_NAME, 'color')
radio_buttons.click()
assert radio_buttons[0].is_selected()

Solution

1. Step 1: Select all radio buttons by group name

   Use find_elements(By.NAME, 'color') to get all radio buttons in the group.

2. Step 2: Click one button and assert selection states

   Click the second button, then assert it is selected and the first is not.

3. Final Answer:

   radio_buttons = driver.find_elements(By.NAME, 'color') radio_buttons[1].click() assert radio_buttons[1].is_selected() and not radio_buttons[0].is_selected() -> Option C

4. Quick Check:

   Click one, check selected and deselected = D [OK]

Hint: Use find_elements and assert one selected, others not [OK]

Common Mistakes:

• Using find_element instead of find_elements
• Not checking deselection of other buttons
• Wrong locator type for radio group
