What is a key practice to improve the reusability of automated test scripts?

Create reusable functions or libraries for common actions like login and logout.

Use absolute XPath for all element locators.

Hard-code all test data within each script.

Write each test as a standalone script with no dependencies.

Why is maintainability an important factor when designing test cases for automation?

Automated tests need to be updated when the application changes, and maintainable tests reduce the effort.

Maintainable tests do not require test data.

Maintainable tests are guaranteed to find more defects.

A test script submits a form and then immediately checks for a success message. The check often fails because the message appears after a variable delay (1–5 seconds). The script currently uses a fixed 2-second sleep. What is the most reliable synchronization technique?

Increase the fixed sleep to 6 seconds

Use a longer implicit wait for all elements

Remove the wait and check immediately

Use an explicit wait that polls for the success message to be visible

A team automates a registration form. They need to test the form with valid and invalid data combinations. The test steps are identical, but the input data and expected validation messages change. Which approach is most efficient?

Write a separate script for each data combination

Use a single script with hard-coded data for one case

Use a data-driven approach with test data in an external file

Use a keyword-driven approach with no data separation
