Mern Unit Test

Purpose

Run unit tests, report failures with enough detail to debug, then (with approval) fix issues and re-run to confirm.

Arguments

• --scope <target> — Limit to apps/web, packages/shared, or all (default: all)
• --no-fix — Report only, don't offer to fix

Workflow

1. Run tests

# All tests
pnpm test

# With coverage (if configured)
pnpm test -- --coverage

# Scoped
pnpm -C apps/web test
pnpm -C packages/shared test

2. Report results

Include:

• Pass/fail/skip counts
• Coverage summary (if available)
• Each failing test: file, test name, assertion diff or error
• If coverage not configured, note this and offer to set it up

3–4. Approval gate, fix and confirm

See /shared-review-workflow for approval gate protocol, fix constraints, and severity definitions.
