Clear and concise reporting is a cornerstone of effective QA work. Well-structured test execution reports allow QA teams to quickly identify issues, understand the quality of a release, and communicate results to stakeholders. As a QA engineer, you often need to process lists of test results and turn them into readable summaries that highlight both individual outcomes and overall trends. This challenge is designed to reinforce your ability to automate the creation of such reports using **Python**.
