March 2025 (2025-03) Monthly Summary: Key features delivered: - codecov-api: Added component-based filtering for badges by introducing a component query parameter on the badge handler to filter coverage by component, with tests validating component IDs, flag regex, unknown components, and missing reports. - codecov/umbrella: Implemented code coverage badge filtering by component via a component query parameter on the badge endpoint, computing and displaying coverage for components defined in the repository YAML config, with tests covering multiple component definitions and missing reports. Major bugs fixed: - No major bugs fixed this month. Overall impact and accomplishments: - Enabled granular, component-level visibility into coverage badges across API and umbrella repositories, improving decision-making and reducing post-release investigation time. - Achieved feature parity and consistency between badge endpoints, aligned with YAML-driven component definitions for reliable scope control. - Expanded test coverage to validate edge cases (unknown components, missing reports), increasing reliability of badge calculations. Technologies/skills demonstrated: - API design and backend filtering logic for component-scoped badges - YAML-config-driven component definitions integration - Comprehensive unit/integration testing for edge cases - Cross-repo collaboration and alignment on feature delivery
