Test Coverage Command

Analyze test coverage and identify gaps: $ARGUMENTS

Your Task

1. Run coverage report: npm test -- --coverage
2. Analyze results - Identify low coverage areas
3. Prioritize gaps - Critical code first
4. Generate missing tests - For uncovered code

Coverage Targets

Coverage Report Analysis

Summary

File           | % Stmts | % Branch | % Funcs | % Lines
---------------|---------|----------|---------|--------
All files      |   XX    |    XX    |   XX    |   XX

Low Coverage Files

[Files below target, prioritized by criticality]

Uncovered Lines

[Specific lines that need tests]

Test Generation

For each uncovered area:

[Function/Component Name]

Location: src/path/file.ts:123

Coverage Gap: [description]

Suggested Tests:

describe('functionName', () => {
  it('should [expected behavior]', () => {
    // Test code
  })

  it('should handle [edge case]', () => {
    // Edge case test
  })
})

Coverage Improvement Plan

1. Critical (add immediately)

   • file1.ts - Auth logic
   • file2.ts - Payment handling

2. High (add this sprint)

   • file3.ts - Core business logic

3. Medium (add when touching file)

   • file4.ts - Utilities

IMPORTANT: Coverage is a metric, not a goal. Focus on meaningful tests, not just hitting numbers.
