test-coverage

name	test-coverage
description	Run tests with coverage and report uncovered lines/branches per class. Use when user wants to check test coverage, find untested code, identify coverage gaps, or mentions /test-coverage command. Also use after green phases to verify new code is well-covered.

/test-coverage - Run Tests with Coverage Report

Usage

/test-coverage usecase
/test-coverage h2
/test-coverage rest RegisterUserController
/test-coverage usecase --focus    # only classes touched in recent git diff

Arguments

First word is the module:

• usecase → :usecase
• h2, rest, email, scheduling, security → :adapters:{name}
• domain → :domain

Optional second word filters the report to classes matching that name.

Optional --focus flag restricts the report to classes changed since the last commit (useful after a green phase to check only new code).

Action

Delegate to .claude/agents/coverage-agent.md which loads .claude/tech/{backend}/templates/testing/coverage-commands.md for commands, report format, gap mapping, and remediation.

Steps:

1. Run tests with coverage (stop if tests fail)
2. Compute module summary from CSV
3. List classes with gaps (apply filter/focus if specified)
4. Extract uncovered lines from XML, read source to show actual code
5. Report results
6. In --focus mode: map gaps to scenarios, classify reachability, update progress.md with red/green steps for reachable gaps, flag dead code for refactor

Agent

• .claude/agents/coverage-agent.md — workflow for gap analysis, reachability classification, progress.md updates

Templates

• .claude/templates/testing/coverage-commands.md — universal workflow: focus mode, module mapping, report format
• .claude/tech/{backend}/templates/testing/coverage-commands.md — tool-specific commands: run, parse, extract
