Coverage Check

Context

Run in parallel:

• •git diff --name-only - get unstaged files
• •git diff -U0 --no-color - get changed line numbers

Commands

Sequential:

1. •npm run test:ci - vitest with coverage
2. •npm run coverage:report - generate lcov/text reports

Workflow

1. •Get unstaged files and line ranges (parallel):
   • •git diff --name-only
   • •git diff -U0 --no-color
2. •Run coverage:
   • •npm run test:ci
   • •npm run coverage:report
3. •Parse coverage/lcov.info (see lcov-format.md for format details)
4. •Map changed lines to coverage data
5. •Report uncovered lines: file.ts:42
6. •Summary: X/Y changed lines covered

Rules

• •Only analyze unstaged changes (git diff)
• •Use sequential commands: test:ci then coverage:report
• •Parse lcov.info for coverage data
• •Report uncovered lines: file.ts:42
• •Ignore files without coverage data (non-code files)
