Testability Scoring

<default_to_action> When assessing testability:

1. RUN assessment against target URL
2. ANALYZE all 10 principles automatically
3. GENERATE HTML report with radar chart
4. PRIORITIZE improvements by impact/effort
5. INTEGRATE with QX Partner for holistic view

Quick Assessment:

# Run assessment on any URL
TEST_URL='https://example.com/' npx playwright test tests/testability-scoring/testability-scoring.spec.js --project=chromium --workers=1

# Or use shell script wrapper
.claude/skills/testability-scoring/scripts/run-assessment.sh https://example.com/

The 10 Principles at a Glance:

Grade Scale:

• A (90-100): Excellent testability
• B (80-89): Good testability
• C (70-79): Adequate testability
• D (60-69): Below average
• F (0-59): Poor testability </default_to_action>

Assessment Workflow

1. Navigate to URL → 2. Collect Metrics → 3. Score Principles
                                              ↓
4. Generate JSON ← 5. Calculate Grades ← 6. Apply Weights
         ↓
7. Generate HTML Report with Radar Chart
         ↓
8. Open in Browser (auto-opens)

Integration Examples

CI/CD Integration

# GitHub Actions
- name: Testability Assessment
  run: |
    timeout 180 .claude/skills/testability-scoring/scripts/run-assessment.sh ${{ env.APP_URL }}

QX Partner Integration

// Combine testability with QX analysis
const qxAnalysis = await Task("QX Analysis", {
  target: 'https://example.com',
  integrateTestability: true
}, "qx-partner");

// Returns combined insights:
// - QX Score: 78/100
// - Testability Integration: Observability 72/100
// - Combined Insight: Low observability may mask UX issues

Programmatic Usage

import { runTestabilityAssessment } from './testability';

const results = await runTestabilityAssessment('https://example.com');
console.log(`Overall: ${results.overallScore}/100 (${results.grade})`);
console.log('Recommendations:', results.recommendations);

Agent Integration

// Run testability assessment
const assessment = await Task("Testability Assessment", {
  url: 'https://example.com',
  generateReport: true,
  openBrowser: true
}, "qe-quality-analyzer");

// Use with QX Partner for holistic analysis
const qxReport = await Task("Full QX Analysis", {
  target: 'https://example.com',
  integrateTestability: true,
  detectOracleProblems: true
}, "qx-partner");

Remember

Testability is an investment, not an afterthought.

Good testability:

• Reduces debugging time
• Enables faster feedback loops
• Makes defects easier to find
• Supports continuous testing

Low scores = High risk. Prioritize improvements by weight × impact.
