Codecov Coverage Skill

Fetch and analyze code coverage data from Codecov for the LinkML project.

When to Use This Skill

  • Before creating a PR: check that coverage won't decrease
  • When adding new code: identify if new files need tests
  • When asked about test coverage or low-coverage areas

Coverage Expectations

PRs must not decrease coverage. The CI will flag coverage decreases.

When adding new code:

  • New modules should target >80% coverage
  • New public functions need at least one test

How to Check Coverage

Quick overall percentage

Use WebFetch on:

https://codecov.io/gh/linkml/linkml/branch/main/graph/badge.txt

Returns plain text like "80%"

Detailed totals (lines, hits, misses)

Use WebFetch on:

https://api.codecov.io/api/v2/github/linkml/repos/linkml/totals

Returns JSON with files count, lines, hits, misses, coverage percentage

File-level coverage report

Use WebFetch on:

https://api.codecov.io/api/v2/github/linkml/repos/linkml/report

Returns per-file coverage data - useful for finding low-coverage files

Why Local Coverage Fails

The UV workspace + src layout breaks local coverage. The .coveragerc specifies source = linkml but packages live at packages/linkml/src/linkml/. Use the Codecov API instead.

Known Low-Coverage Areas

These areas currently have low coverage and may need tests:

  • generators/rustgen/ - experimental
  • generators/dotgen.py - ~47%
  • converter/cli.py - ~53%
  • workspaces/ - minimal coverage
