Question 23. Which ActionChains method performs a mouse hover over an element? A) move_to_element() B) hover() C) click_and_hold() D) drag_and_drop() Answer: A Explanation: move_to_element(element).perform() moves the mouse cursor over the target element, simulating a hover. Question 24. What is the default polling interval for Selenium’s WebDriverWait? A) 0.1 seconds B) 0.5 seconds C) 1 second D) 2 seconds Answer: C Explanation: WebDriverWait polls the DOM every 500 milliseconds by default, but the effective interval is 0.5 s; however, the timeout parameter is expressed in seconds, and the internal default poll is 0.5 s. Since the question asks for the
Tester using Python Certification Exam Guide
“default polling interval,” the correct answer is 0.5 seconds, which corresponds to option B. Corrected Answer: B Explanation: Selenium’s WebDriverWait checks the condition every 500 ms (0.5 seconds) unless a custom poll frequency is set. Question 25. Which of the following is an example of a Fluent Wait? A) driver.implicitly_wait(10) B) WebDriverWait(driver, 15).until(EC.title_contains("Home")) C) wait = FluentWait(driver).with_timeout(20).polling_every(2).ignore_all([NoSuchElementExc eption]) D) time.sleep(5) Answer: C Explanation: Fluent Wait allows specifying timeout, polling frequency, and ignored exceptions, providing fine-grained control. Question 26. In PyTest, which decorator is used to declare a fixture that runs before each test function? A) @pytest.fixture(scope="module") B) @pytest.fixture(scope="function") C) @pytest.setup D) @pytest.before Answer: B Explanation: The default scope is “function,” but explicitly setting scope="function" indicates the fixture runs for each test.

Explanation: Executing JavaScript scrollIntoView() via execute_script brings the element into the viewport. Question 38. What is the primary purpose of the __name__ == "__main__" guard in Python test scripts? A) To define a class name B) To ensure code runs only when the script is executed directly, not when imported C) To declare global variables D) To start a Selenium session automatically Answer: B Explanation: The guard prevents code from running during imports, enabling reusable modules. Question 39. Which of the following is a best practice when handling dynamic element IDs in Selenium? A) Use absolute XPath that includes the dynamic ID B) Use a CSS selector that relies on stable attributes like class or data-test-id C) Hard-code the ID values in the script D) Use Thread.sleep() to wait for the ID to appear Answer: B Explanation: Stable attributes make locators resilient to ID changes; absolute XPaths are brittle.

Tester using Python Certification Exam Guide
B) driver.find_element(By.PARTIAL_LINK_TEXT, "Hom") C) driver.find_element(By.ID, "Home") D) Both A and B are valid Answer: C Explanation: By.ID locates by element ID, not link text; the other two are correct link-text strategies.

A) Only the test scripts B) A combination of data-driven and keyword-driven modules with a central driver class C) Only the reporting module D) None of the above Answer: B Explanation: Hybrid frameworks blend multiple patterns (data-driven, keyword-driven) and often include a central driver for orchestration. Question 45. Which Python built-in function can be used to pause execution for a fixed time, though it is discouraged for synchronization? A) time.wait() B) sleep() from time module C) pause() from os module D) delay() from sys module Answer: B Explanation: time.sleep(seconds) halts execution but is not recommended for dynamic waits in Selenium.
