test-gap

Surface the lines you just changed that have zero test coverage — before the PR review does.

TL;DR: /test-gap → markdown table of files where your diff added lines that nothing tests yet.

Quick start

# After running your test suite with coverage:
python3 -m pytest --cov --cov-report=xml         # produces coverage.xml
/test-gap                                         # in Claude Code

Or directly:

python3 scripts/gap.py --format md
python3 scripts/gap.py --base develop --report build/lcov.info

How it works

1. Reads git diff --unified=0 <base>..HEAD and collects the added line numbers per file.
2. Parses the coverage report into a {file: {covered_lines}} map.
3. Intersects: any added line not in the covered set is reported as a gap.
4. Sorts the table by uncovered-count descending so the worst offenders surface first.

Limitations

• Coverage is taken at face value — it doesn't know about branch coverage or test quality.
• Cobertura paths must match diff paths; configure your runner to emit project-relative paths.
• Empty diffs and no-test repos are handled gracefully (no output).

Examples

Step-by-step walkthroughs with real input fixtures and the helper's actual output live in examples/. Three or four scenarios per plugin — from the happy path to the edge cases the test suite guards.
