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/- experimentalgenerators/dotgen.py- ~47%converter/cli.py- ~53%workspaces/- minimal coverage
