Automating the process of updating test case statuses saves time and reduces human error in quality assurance workflows. By programmatically comparing the `expected` and `actual` results for each test case, you can instantly determine whether each test passes or fails. This challenge will help you practice using Python to efficiently update test case records, a common task when managing large test suites.
