Quality Metrics

<default_to_action> When measuring quality or building dashboards:

MEASURE outcomes (bug escape rate, MTTD) not activities (test count)
AVOID vanity metrics: 100% coverage means nothing if tests don't catch bugs
SET thresholds that drive behavior (quality gates block bad code)
TREND over time: Direction matters more than absolute numbers </default_to_action>

Quick Reference Card

When to Use

Building quality dashboards
Defining quality gates
Evaluating testing effectiveness
Justifying quality investments

Quality Gate Thresholds

| Metric | Blocking Threshold | Warning | |--------|-------------------|---------| | Test pass rate | 100% | - | | Critical coverage | > 80% | > 70% | | Security critical | 0 | - | | Performance p95 | < 200ms | < 500ms | | Flaky tests | < 2% | < 5% |

Dashboard Design

// Agent generates quality dashboard
await Task("Generate Dashboard", {
  metrics: {
    delivery: ['deployment-frequency', 'lead-time', 'change-failure-rate'],
    quality: ['bug-escape-rate', 'test-effectiveness', 'defect-density'],
    stability: ['mttd', 'mttr', 'availability'],
    process: ['code-review-time', 'flaky-test-rate', 'coverage-trend']
  },
  visualization: 'grafana',
  alerts: {
    critical: { bug_escape_rate: '>20%', mttr: '>24h' },
    warning: { coverage: '<70%', flaky_rate: '>5%' }
  }
}, "qe-quality-analyzer");

Quality Gate Configuration

{
  "qualityGates": {
    "commit": {
      "coverage": { "min": 80, "blocking": true },
      "lint": { "errors": 0, "blocking": true }
    },
    "pr": {
      "tests": { "pass": "100%", "blocking": true },
      "security": { "critical": 0, "blocking": true },
      "coverage_delta": { "min": 0, "blocking": false }
    },
    "release": {
      "e2e": { "pass": "100%", "blocking": true },
      "performance_p95": { "max_ms": 200, "blocking": true },
      "bug_escape_rate": { "max": "10%", "blocking": false }
    }
  }
}

Agent-Assisted Metrics

// Calculate quality trends
await Task("Quality Trend Analysis", {
  timeframe: '90d',
  metrics: ['bug-escape-rate', 'mttd', 'test-effectiveness'],
  compare: 'previous-90d',
  predictNext: '30d'
}, "qe-quality-analyzer");

// Evaluate quality gate
await Task("Quality Gate Evaluation", {
  buildId: 'build-123',
  environment: 'staging',
  metrics: currentMetrics,
  policy: qualityPolicy
}, "qe-quality-gate");
