  Analyze and expand test coverage using intelligent prioritization.
  Use when checking coverage status, finding testing opportunities, or expanding coverage systematically.

Test Coverage Management

Track and expand test coverage systematically.

Usage

  • •/testing:test-coverage status - Current coverage metrics
  • •/testing:test-coverage opportunities - Find high-impact files
  • •/testing:test-coverage expand [area] - Expand specific area

Priority Matrix

High Priority (Zero Coverage)

  • •Core business logic files
  • •Utility functions
  • •Data stores

Medium Priority (Partial Coverage)

  • •Modules with < 50% coverage

Lower Priority

  • •Well-covered files needing edge cases

Workflow

  1. •Run coverage report to identify targets
  2. •Pick 2-3 high-priority files
  3. •Create tests using appropriate patterns (see testing:unit-tests skill)
  4. •Verify coverage improvement
  5. •Repeat

Reports

bash
# HTML report
<test-coverage-command> --reporter=html

# JSON data
<test-coverage-command> --reporter=json

# Summary only
<test-coverage-command> --reporter=text-summary

Expansion Process

  1. •Identify files with zero or low coverage
  2. •Prioritize by: business impact, change frequency, complexity
  3. •Create tests covering: happy path, edge cases, error conditions
  4. •Verify improvement
  5. •Track progress over time
