Fixing problem when coverage is calculated for backend+frontend separately but smh is shown for 1/2

📝 Walkthrough

Walkthrough

A new Codecov configuration file is added at .github/codecov.yml that establishes flag management rules. The configuration enables carryforward for coverage data and defines scope-based flags for backend (backend/app/) and frontend (frontend/src/) paths.

🐰 Hops with joy at coverage clear,
Flags for back and front appear,
Carryforward through the night,
Coverage shining ever bright!

1-13: Consider adding status check configuration for complete flag separation.

To fully address the issue where "coverage is shown for 1/2," you may need to add coverage.status configuration to define how each flag is reported in GitHub status checks.

🔎 Example configuration with status checks
flag_management:
  default_rules:
    carryforward: true

  individual_flags:
    - name: backend
      paths:
        - backend/app/
      carryforward: true
    - name: frontend
      paths:
        - frontend/src/
      carryforward: true

coverage:
  status:
    project:
      default: false
      backend:
        flags:
          - backend
        target: auto
      frontend:
        flags:
          - frontend
        target: auto
    patch:
      default: false
      backend:
        flags:
          - backend
      frontend:
        flags:
          - frontend

This ensures Codecov creates separate status checks for backend and frontend coverage, which should resolve the "1/2" display issue.

5-13: Configuration paths are correct; no action required.

Both backend/app/ and frontend/src/ paths exist in the repository and are properly configured in the individual_flags section.

Codecov flag_management carryforward configuration documentation 2024 2025

💡 Result:

Summary — Codecov flag_management + carryforward (2024–2025)

  • Newer/recommended approach: use the flag_management section in codecov.yml with default_rules and individual_flags (automatic flag management). Example shows default_rules.carryforward: true. [1][2]

  • You can set carryforward per-flag under individual_flags or under the legacy flags root (carryforward: true/false). Carryforward requires an initial full upload of all flags to establish the baseline. [2][3][5]

  • Typical config examples:

    • Automatic default rule:
      flag_management:
      default_rules:
      carryforward: true
      statuses: …
    • Per-flag exception:
      flag_management:
      individual_flags:
      - name: feature_1
      carryforward: true
      statuses: …
    • Legacy flags block:
      flags:
      ui:
      carryforward: true
      paths: … [1][2][3]
  • Notes: Carryforward is intended for monorepos/partial-test setups; read full Carryforward Flags docs before enabling. [5]

Carryforward configuration requires initial full flag upload baseline.

The carryforward: true setting for both backend and frontend flags is appropriate for this monorepo setup and allows Codecov to reuse previous coverage data when a flag is not uploaded in a CI run. However, carryforward requires that all flags are uploaded at least once to establish the baseline coverage metrics. Ensure your CI pipeline uploads both backend and frontend test coverage on the initial run and maintains consistent uploads thereafter.

🤖 Prompt for AI Agents
.github/codecov.yml lines 1-3: carryforward: true is set but requires an initial
full upload of all flags to establish baseline; update your CI to ensure both
backend and frontend coverage reports are uploaded at least once (and on
subsequent runs) so Codecov can carry forward missing-flag data — modify the
pipeline to run tests for both projects, generate coverage artifacts for each,
and upload them to Codecov in the initial CI execution and keep uploads
consistent thereafter.
