   • ABusiness layer
   • BFunctional layer
   • CTechnical layer
   • DTest case layer

   A test automation team is writing test cases for an e-commerce application. They want to ensure that if the checkout process changes (e.g., a new step is added), only a limited number of test cases need to be updated. Which approach best achieves this?

   • APut the checkout steps in the technical layer as a reusable function, since it involves UI interactions.
   • BUse a data-driven approach where the checkout steps are defined in an external file, and test cases read from that file.
   • CWrite each test case to perform the checkout steps directly, so that they are independent and can be modified individually.
   • DCreate a business layer method 'checkoutWithPayment(paymentDetails)' that encapsulates the entire checkout workflow, and have test cases call this method.

   A test automation framework has a test case that directly interacts with the WebDriver to check if an element is displayed, and also contains business assertions like 'order confirmation is shown'. The team wants to improve maintainability. What is the best refactoring step?

   • AMove the element display check into the functional layer as a method like 'isElementDisplayed(locator)', and have the test case use that method.
   • BCreate a new test case that duplicates the WebDriver interaction for better coverage.
   • CMove the business assertion into the technical layer, since it is a verification step.
   • DKeep the direct WebDriver interaction in the test case, but add comments to explain what it does.
