ci: add code coverage with 80% line threshold#63
Merged
Conversation
Add test:coverage npm script using Node.js built-in test coverage with --test-coverage-lines=80 threshold. Excludes thin VS Code API wrapper files (extension.ts, statusBar.ts, configureMcp.ts, setupWorkspace.ts, showStatus.ts) that are tested by integration tests rather than unit tests. Add coverage check step to CI workflow (Linux-only in unit-test job). Include coverage in the npm run check gate. Current coverage: 82.65% line, 86.27% branch, 86.69% function.

The patchloomCli tests depend on the patchloom binary being on PATH. In CI on Ubuntu, the binary is not available so tests skip, causing the test file's coverage to drop from 88% to 17% and failing the 80% threshold. Exclude this environment-dependent test file from coverage measurement. Also add --test-coverage-include to limit coverage to source files only (not test files) for cleaner measurement.
