test: Add branch coverage tests for constants files (94.73% coverage achieved) by Copilot · Pull Request #672 · Hack23/cia-compliance-manager

Copilot · 2025-11-19T18:53:35Z

Pull Request Description

Adds comprehensive branch coverage tests for constants files to meet v1.0 ISMS requirement of 70%+ branch coverage. Achieved 94.73% branch coverage across constants directory.

Key Coverage Improvements:

appConstants.ts: 0% → 100% branches (tests mapOptionsToConstants with null/undefined/transform cases)
businessConstants.ts: 0% → 100% branches (tests helper functions with case-insensitive lookups)
costConstants.ts: 0% → 100% branches (tests formatCurrency, formatPercentage, calculation functions)
riskConstants.ts: 0% → 100% branches (tests color/risk mappings with fallbacks)
securityLevels.ts: 0% → 100% branches (tests bidirectional level conversions)
uiConstants.ts: 16.66% → 100% branches (tests icon getters with invalid inputs)

Test Strategy:

Edge cases: null, undefined, empty strings, out-of-range values
All conditional branches: if/else, ternary operators, switch statements
Helper function validation: valid/invalid inputs, boundary conditions
Case-insensitive lookups and default fallbacks
Consolidated assertions for improved maintainability
Explicit boundary tests for rounding behavior
Type-safe mock data with proper TypeScript interface compliance

// Example: Testing mapOptionsToConstants with consolidated assertions
describe("mapOptionsToConstants", () => {
  it("returns undefined when options is null", () => {
    const result = mapOptionsToConstants(null, "description");
    expect(Object.values(result).every(v => v === undefined)).toBe(true);
  });

  it("applies transform function when provided", () => {
    const transform = (value: string, level: string) => `${level}: ${value}`;
    const result = mapOptionsToConstants(mockOptions, "description", transform);
    expect(result.NONE).toBe("None: None description");
  });
  
  // Transform function properly handles optional fields
  it("applies transform function to numeric fields", () => {
    const transform = (value: number | undefined) => value ? value * 2 : 0;
    const result = mapOptionsToConstants(mockOptions, "capex", transform);
    expect(result.LOW).toBe(10);
  });
});

// Example: Testing formatCurrency with rounding boundaries
describe("formatCurrency", () => {
  it("rounds down correctly at .49 boundary", () => {
    const formatted = formatCurrency(1234.49);
    expect(formatted).toContain("$1,234");
  });

  it("rounds up correctly at .50 boundary", () => {
    const formatted = formatCurrency(1234.50);
    expect(formatted).toContain("$1,235");
  });
});

Original prompt

This section details on the original issue you should resolve

<issue_title>🧪 Add branch coverage tests for constants files (currently 0% branch coverage)</issue_title>
<issue_description>## 🤖 Recommended Agent: @testing-agent

This issue is best handled by the Testing Agent - an expert in test coverage improvement and branch testing.

🎯 Objective

Add comprehensive branch coverage tests for constants files to ensure conditional logic is properly tested and achieve 70%+ branch coverage for v1.0 release.

📋 Background

Many constant files in src/constants/ have 0% branch coverage despite containing conditional logic, type guards, and data transformations. This creates risk of untested code paths and reduces overall branch coverage below the 70% ISMS requirement.

📊 Current State (Measured Metrics)

Constants Files with 0% or Low Branch Coverage:

src/constants/appConstants.ts: 90.24% statements / 0% branches
src/constants/businessConstants.ts: 53.33% statements / 0% branches
src/constants/costConstants.ts: 80% statements / 0% branches
src/constants/riskConstants.ts: 86.66% statements / 0% branches
src/constants/securityLevels.ts: 72.72% statements / 0% branches
src/constants/testIds.ts: 81.66% statements / 0% branches (64.51% functions)
src/constants/uiConstants.ts: 50% statements / 16.66% branches

Overall Impact:

Current branch coverage: 64.9%
Target branch coverage: 70%
Gap: 5.1% - constants contribute significantly to this gap

✅ Acceptance Criteria

All constants files have ≥70% branch coverage
Test files created for each constants file with conditional logic
All conditional branches tested (if/else, ternary operators, switch statements)
All exported helper functions tested with edge cases
Overall project branch coverage ≥70%
All tests follow Vitest + existing test patterns

🛠️ Implementation Guidance for @testing-agent

Test Files to Create:

src/constants/appConstants.test.ts - Test app configuration logic
src/constants/businessConstants.test.ts - Test business logic constants
src/constants/costConstants.test.ts - Test cost calculation constants
src/constants/riskConstants.test.ts - Test risk assessment logic
src/constants/securityLevels.test.ts - Test security level mappings
src/constants/uiConstants.test.ts - Test UI configuration branches
src/constants/testIds.test.ts - Test ID generation functions

Agent-Specific Testing Strategy:

✅ Use Vitest for all constant file tests
✅ Follow Arrange-Act-Assert pattern
✅ Test all conditional branches: if/else, ternary operators, switch statements
✅ Test helper functions with edge cases (null, undefined, empty strings)
✅ Test type guards and validation functions
✅ Use descriptive test names that explain what is being tested

Example Test Pattern:

// src/constants/securityLevels.test.ts
import { describe, it, expect } from 'vitest';
import { 
  SECURITY_LEVELS, 
  getSecurityLevelName, 
  isValidSecurityLevel 
} from './securityLevels';

describe('securityLevels', () => {
  describe('SECURITY_LEVELS constant', () => {
    it('contains all required levels', () => {
      expect(SECURITY_LEVELS).toContain('None');
      expect(SECURITY_LEVELS).toContain('Low');
      expect(SECURITY_LEVELS).toContain('Moderate');
      expect(SECURITY_LEVELS).toContain('High');
      expect(SECURITY_LEVELS).toContain('Very High');
    });
  });

  describe('getSecurityLevelName', () => {
    it('returns correct name for each level', () => {
      expect(getSecurityLevelName('None')).toBe('No Security');
      expect(getSecurityLevelName('Low')).toBe('Basic Security');
      expect(getSecurityLevelName('High')).toBe('Advanced Security');
    });

    it('handles invalid levels', () => {
      expect(getSecurityLevelName('invalid')).toBe('Unknown');
    });

    it('handles edge cases', () => {
      expect(getSecurityLevelName(null as any)).toBe('Unknown');
      expect(getSecurityLevelName(undefined as any)).toBe('Unknown');
      expect(getSecurityLevelName('')).toBe('Unknown');
    });
  });

  describe('isValidSecurityLevel', () => {
    it('returns true for valid levels', () => {
      SECURITY_LEVELS.forEach(level => {
        expect(isValidSecurityLevel(level)).toBe(true);
      });
    });

    it('returns false for invalid levels', () => {
      expect(isValidSecurityLevel('invalid')).toBe(false);
      expect(isValidSecurityLevel('')).toBe(false);
      expect(isValidSecurityLevel(null as any)).toBe(false);
    });
  });
});

Comments suppressed due to low confidence (1)

src/constants/riskConstants.test.ts:1

This test creates arbitrary numeric mappings to validate business logic relationships that are already statically defined. This adds complexity without testing actual branches in the code. The inverse relationship is already tested explicitly in line 230-235. Remove this redundant test.

[nitpick] Repetitive assertions checking all five security levels individually. Consider consolidating to: expect(Object.values(result).every(v => v === undefined)).toBe(true); This reduces duplication and makes the test more maintainable.

Suggested change

expect(result.NONE).toBeUndefined();

expect(result.LOW).toBeUndefined();

expect(result.MODERATE).toBeUndefined();

expect(result.HIGH).toBeUndefined();

expect(result.VERY_HIGH).toBeUndefined();

});

it("returns undefined values when options is undefined", () => {

const result = mapOptionsToConstants(undefined as unknown as Record<string, CIADetails>, "description");

expect(result.NONE).toBeUndefined();

expect(result.LOW).toBeUndefined();

expect(result.MODERATE).toBeUndefined();

expect(result.HIGH).toBeUndefined();

expect(result.VERY_HIGH).toBeUndefined();

expect(Object.values(result).every(v => v === undefined)).toBe(true);

});

it("returns undefined values when options is undefined", () => {

const result = mapOptionsToConstants(undefined as unknown as Record<string, CIADetails>, "description");

expect(Object.values(result).every(v => v === undefined)).toBe(true);

Applied in commit d504104. Consolidated the repetitive assertions using Object.values(result).every(v => v === undefined) for both null and undefined test cases.

+      // Should be rounded to nearest dollar
+      expect(formatted).toContain("1,235");
+    });
+


The comment 'Should be rounded to nearest dollar' implies rounding behavior, but the test doesn't verify the rounding logic itself (e.g., 1234.49 → $1,234, 1234.50 → $1,235). Consider adding explicit test cases for rounding boundaries to properly document and verify this behavior.

Suggested change

it("rounds down correctly at .49 boundary", () => {

const formatted = formatCurrency(1234.49);

expect(formatted).toContain("$");

expect(formatted).toContain("1,234");

});

it("rounds up correctly at .50 boundary", () => {

const formatted = formatCurrency(1234.50);

expect(formatted).toContain("$");

expect(formatted).toContain("1,235");

});

Applied in commit d504104. Added explicit rounding boundary tests:

.49 boundary: rounds down to $1,234

.50 boundary: rounds up to $1,235

This properly documents and verifies the rounding behavior.

Fixed in commit 10e1548. The TypeScript compilation errors were caused by:

Missing required fields: Added businessImpact and recommendations to all mock CIADetails objects
Transform function type: Updated to handle number | undefined for optional fields like capex

Build now passes successfully. All 212 tests passing.
