What metrics would you measure?

In QA and test automation, it is important to measure metrics that help assess product quality and testing efficiency. Key metrics:

• Test Coverage — the percentage of code or functionality covered by tests.
• Percentage of successful/failed tests — helps understand build stability.
• Test execution time — important for evaluating regression testing speed.
• Number of defects found — total and by categories (critical, medium, low).
• Time to fix a defect (Mean Time to Repair, MTTR) — how long it takes to fix bugs.
• Defect Density — number of defects per unit of code or functionality.
• Test automation (%) — proportion of automated tests out of the total.

These metrics help control quality, identify bottlenecks, and optimize testing processes.
