Test Framework Layers

• Driver Layer: Manages browser setup and teardown (utils/selenium_driver.py).
• Page Objects: Encapsulate radio button elements and interactions (pages/radio_buttons_page.py).
• Tests: Contains test cases that use page objects to verify radio button behavior (tests/test_radio_buttons.py).
• Utilities: Helper functions and driver management (utils/selenium_driver.py).
• Configuration: Stores environment settings like URLs and browser types (config/config.yaml).

Configuration Patterns

Use a YAML file (config/config.yaml) to store environment URLs, browser choice, and credentials.

Example config.yaml:

environment:
  url: "https://example.com/radio-buttons"
browser: "chrome"

Use conftest.py with pytest fixtures to read config and initialize the driver accordingly.

Test Reporting and CI/CD Integration

• Use pytest with pytest-html plugin to generate HTML reports in reports/.
• Integrate tests in CI pipelines (GitHub Actions, Jenkins) to run on every commit.
• Reports show pass/fail status of radio button interaction tests with screenshots on failure.

Best Practices

• Use Page Object Model: Encapsulate radio button locators and actions in page classes.
• Explicit Waits: Wait for radio buttons to be clickable before interacting.
• Clear Assertions: Assert radio button selection state after clicking.
• Reusable Fixtures: Use pytest fixtures for driver setup and teardown.
• Configurable Browsers: Allow browser choice via config for flexibility.

Self Check

Where in this folder structure would you add a new page object for a group of radio buttons on a different page?

Key Result

Use Page Object Model with explicit waits and pytest fixtures to organize radio button interaction tests in Selenium Python.

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
