test: raise unit coverage to ~99.9% and enforce coverage thresholds#65
Merged
Conversation
Add unit tests across the CLI (commands, core, generators, prompts, utils, and the entry dispatcher), bringing line coverage from 23% to 99.9%. Tests are co-located *.test.ts, follow the repo's dependency-injection style, and mock external boundaries (@clack/prompts, fs, child_process, network, keyring) without changing any source. Add Vitest coverage thresholds (lines/statements 99, functions 99, branches 95) as a regression floor. The remaining uncovered lines are unreachable branches (a private multiline-env helper in the docker generator).

Summary
Adds a comprehensive unit test suite across the CLI and sets a Vitest coverage floor so coverage cannot silently regress.
*.test.ts, follow the repo's dependency-injection style, and mock external boundaries (@clack/prompts, fs, child_process, network, keyring) without changing any source.Verification
npm run buildpasses.npm run coveragepasses: 46 test files / 548 tests (1 gated e2e file skipped). All files at 99.88% lines, 96.92% branches, above the configured floors.Notes
This branch is the test-expansion work rebased cleanly onto current
main. The originaltest/coverage-pushbranch predated amainhistory rewrite, so only the single test commit was lifted onto the current base to keep the diff focused.
