What this skill does
Test Report Generator Overview Generate structured, human-readable test reports from raw test runner output including JUnit XML, Jest JSON, pytest results, and coverage data. Produces Markdown summaries, HTML dashboards, and CI-compatible annotations. Prerequisites Test results in a parseable format (JUnit XML, Jest --json, pytest --junitxml, or TAP) Coverage data files (Istanbul coverage-summary.json, lcov.info, or coverage.xml) Node.js or Python available for report generation scripts Git history accessible for trend analysis across commits Instructions 1. Locate all test result files using Glob patterns (/junit.xml, /test-results.json, /coverage/lcov.info). 2. Parse each result file and extract: Total test count, passed, failed, skipped, and error counts. Execution duration per test suite and per individual test. Failure messages, stack traces, and assertion details. 3. Parse coverage data and extract: Line, branch, function, and statement coverage percentages. Per-file coverage breakdown identifying files below threshold. Uncovered line ranges for targeted improvement. 4. Compute aggregate metrics: Overall pass rate as a percentage. Total execution time and average test duration. Top 10 slowest tests with file paths and durations. Coverage delta compared to the previous commit (if git history is available). 5. Generate a Markdown report with sections for summary, failures, coverage, and performance. 6. Optionally generate an HTML report with sortable tables and coverage heatmaps. 7. Write CI-compatible output (GitHub Actions job summary, GitLab report artifacts, or Slack webhook payload). …
