A good test report answers three questions: "Can we release?", "What are the risks?", and "What needs attention?" If your report does not answer these, it is just data, not information.
Strong answers cover: real-time test execution dashboards, trend analysis (pass rates over time, flake rates), linking test results to specific builds and code changes, highlighting blockers and regressions, and making reports actionable (not just informational). Best candidates discuss tailoring reports for different audiences: developers want failure details, managers want quality trends.
Tests communication and tooling skills. QA teams that cannot communicate quality status clearly lose influence over release decisions. Candidates who build effective reporting earn a seat at the table.
