Summary

Implemented comprehensive Codecov integration with modern 2025 features including PR comments, status checks, coverage thresholds, and detailed configuration.

Changes

Configuration File (codecov.yml)

• Complete Codecov YAML configuration validated with official API
• Settings for CI integration, report aging, branch comparison

Coverage Thresholds

• Project target: 95% minimum coverage
• Patch target: 95% for new code
• Threshold: 1% allowed drop for project, 5% for patches
• Status checks will fail if coverage drops below thresholds

PR Comment Integration

• Modern condensed layout: condensed_header, condensed_files, condensed_footer
• Automatic comments on every PR with coverage diff
• Behavior: Update existing comment instead of creating new ones
• Shows project coverage changes and file-level details

Status Checks

• GitHub status checks for blocking PRs below threshold
• Project-level coverage comparison against base
• Patch-level coverage for new code only
• Changes status for informational diff display

Ignore Paths

• Tests: tests/**/*, **/tests.rs
• Benchmarks: benches/**/*, **/benches.rs
• Examples: examples/**/*
• Focused coverage on production code only

GitHub Integration

• Annotations enabled for inline coverage feedback
• Requires both base and head reports for comparison
• CI must pass before coverage processing

Benefits

• Quality Enforcement: 95% coverage target maintains high test standards
• PR Visibility: Automatic coverage reports in every PR
• Regression Prevention: Status checks block coverage drops
• Developer Feedback: Inline annotations show uncovered lines
• Historical Tracking: Coverage trends visible on Codecov dashboard

Badge Status

Badge already configured in README.template.md with token:

[![codecov](https://codecov.io/gh/RAprogramm/masterror/graph/badge.svg?token=OD4F7LWWB8)](https://codecov.io/gh/RAprogramm/masterror)

Badge will display after first successful coverage upload to Codecov.

Validation

Configuration validated with Codecov API:

$ curl --data-binary @codecov.yml https://codecov.io/validate
Valid!

Test Plan

• Configuration validated successfully
• All 157 tests pass
• Cargo fmt and clippy pass
• No regression in existing functionality

Next Steps

After merge:

• Monitor first PR with Codecov comments
• Verify status checks appear correctly
• Check badge visibility after coverage upload
• Adjust thresholds if needed based on actual coverage

Make test report generation shell-agnostic for Windows runs

The test matrix now targets windows-latest, but the new "Generate test report" step still uses bash-only syntax (\ line continuation and || true) without overriding the default shell. Windows runners execute run steps in PowerShell, so this command fails before producing test-results-*.json, and the subsequent artifact upload step fails because the file is missing. As a result, every Windows test job will fail and the multi-platform CI introduced here never succeeds. Specify shell: bash (or rewrite the command in PowerShell) so the step works on Windows.
