What tools and methods have you used for analyzing testing data?

For test data analysis, I used the following tools and methods:

• JIRA and TestRail — for collecting and tracking test results, bug analysis, and coverage metrics.
• Excel or Google Sheets — for creating pivot tables, charts, and visualizing test results.
• Allure Report — for generating detailed reports on automated tests with easy navigation.
• Grafana and Prometheus — for monitoring testing metrics in real-time (e.g., execution time, number of failed tests).

Analysis methods include:

• Trend analysis of defect counts and their priorities.
• Identifying bottlenecks and unstable tests based on failure frequency.
• Cross-analysis of requirements coverage and test results.

Example: after running automated tests, I export the Allure report, analyze failed tests, create a stability chart in Excel, and based on this, propose test set optimization.
