Phase 4: CI/CD Quality Gates Implementation Summary

Issue: #69 Implementation Date: 2025-11-29 Status: ✅ Complete

Overview

Implemented comprehensive CI/CD quality gates that integrate with GitHub Actions and the existing ControlLoopReporter system. Quality gates automatically evaluate test results, coverage, and security metrics to make intelligent deployment decisions.

Files Created

1. Quality Gate Scripts

/workspaces/agentic-qe-cf/scripts/quality-gate.sh

• Type: Bash script
• Purpose: Fallback quality gate evaluation for environments without Node.js
• Features:
  • Parses Jest test output
  • Extracts coverage from coverage-summary.json
  • Evaluates quality thresholds
  • Generates control-loop feedback JSON
  • Creates human-readable reports
• Exit Codes:
  • 0: Quality gates passed
  • 1: Quality gates failed
  • 2: Script error

/workspaces/agentic-qe-cf/scripts/quality-gate.ts

• Type: TypeScript/Node.js script
• Purpose: Primary quality gate evaluation using ControlLoopReporter
• Features:
  • Direct integration with ControlLoopReporter
  • Extracts test results and coverage data
  • Generates structured feedback using reporting system
  • Creates PR-formatted comments
  • Produces machine-readable deployment decisions
• Integration: Uses src/reporting/reporters/ControlLoopReporter.ts

2. GitHub Actions Workflows

/workspaces/agentic-qe-cf/.github/workflows/quality-gate.yml

• Type: GitHub Actions workflow
• Triggers:
  • Push to main or develop branches
  • Pull requests to main or develop
  • Manual workflow dispatch with custom thresholds
• Jobs:
  1. quality-gate: Runs tests, evaluates gates, posts PR comments
  2. deploy: Conditional deployment (only if gates pass)
• Features:
  • Runs unit and integration tests
  • Evaluates quality gates using TypeScript script
  • Fallback to Bash script if TypeScript fails
  • Posts results as PR comments
  • Updates commit status
  • Uploads quality reports as artifacts
  • Blocks workflow if gates fail

3. Reusable GitHub Action

/workspaces/agentic-qe-cf/.github/actions/quality-gate/action.yml

Integration Points

1. ControlLoopReporter

Quality gates use the existing ControlLoopReporter from the reporting system:

import { ControlLoopReporter, ControlLoopConfig } from '../src/reporting';

const config: ControlLoopConfig = {
  minPassRate: 0.95,
  minCoverage: 80,
  maxCriticalVulnerabilities: 0,
  maxHighVulnerabilities: 2
};

const reporter = new ControlLoopReporter(config);
const output = reporter.report(aggregatedResults);
const feedback: ControlLoopFeedback = JSON.parse(output.content);

// Deployment decision
process.exit(feedback.signals.canDeploy ? 0 : 1);

2. Alerting System

Quality gate metrics integrate with Prometheus alerting rules (config/alerting-rules.yml):

- alert: QualityGateFailed
  expr: aqe_quality_gate_pass_rate < 1.0
  labels:
    severity: error
    component: quality
    alert_type: quality_gate

3. Test Execution

Quality gates run after test execution:

# Unit tests
npm run test:unit

# Integration tests
npm run test:integration

# Quality gate evaluation
npx ts-node scripts/quality-gate.ts

Default Quality Thresholds

Metric	Threshold	Severity
Test Pass Rate	≥ 95%	Critical
Code Coverage	≥ 80%	High
Critical Vulnerabilities	0	Critical
High Vulnerabilities	≤ 2	High
Quality Score	≥ 70	High

Usage Examples

Example 1: Local Testing

# Run tests
npm run test:unit
npm run test:integration

# Evaluate quality gates
npx ts-node scripts/quality-gate.ts \
  --min-coverage 80 \
  --min-pass-rate 0.95 \
  --pr-comment

Example 2: GitHub Actions (Using Reusable Action)

- name: Quality Gate
  uses: ./.github/actions/quality-gate
  with:
    min-coverage: '80'
    min-pass-rate: '0.95'
    fail-on-violation: 'true'

Example 3: Custom Thresholds via Workflow Dispatch

workflow_dispatch:
  inputs:
    min_coverage:
      default: '85'
    min_pass_rate:
      default: '0.98'
