Engineering Discipline

Quality-First Engineering

Every feature is architected with Test-Driven (TDD) and Behavior-Driven (BDD) precision

stockService.test.ts 
describe('StockAlertService', () => {
  it('should trigger alert when stock falls below reorder point', () => {
    const alertService = new StockAlertService();
    const result = alertService.evaluate({ stock: 5, threshold: 10 });

    expect(result.needsAlert).toBe(true);
    expect(result.reorderUnits).toBe(50);
  });
});
// ✕ StockAlertService is not defined (FAIL)
FAILING (Red) TypescriptLn 10

Specify the desired behavior before writing any production code.

stockService.ts 
export class StockAlertService {
  evaluate({ stock, threshold }: { stock: number; threshold: number }) {
    if (stock < threshold) {
      return { needsAlert: true, reorderUnits: 50 };
    }
    return { needsAlert: false, reorderUnits: 0 };
  }
}
// ✓ StockAlertService › triggers alert (PASS: 4ms)
PASSING (Green) TypescriptLn 9

Write the minimal clean logic needed to make the specification pass.

stockService.ts (Optimized) 
export class StockAlertService {
  constructor(private readonly reorderStrategy: ReorderStrategy = new DynamicEOQStrategy()) {}

  evaluate(inventoryItem: InventoryItem): StockEvaluation {
    const needsAlert = inventoryItem.stock < inventoryItem.threshold;
    const reorderUnits = needsAlert ? this.reorderStrategy.calculate(inventoryItem) : 0;
    return { needsAlert, reorderUnits, evaluatedAt: new Date() };
  }
}
// ✓ All 24 unit & integration tests passing (100% Coverage)
CLEAN & GREEN TypescriptLn 10

Refactor for patterns, maintainability, and clarity while tests guarantee zero breakage.

Next-Gen Development Workflow

AI Spec-Driven Architecture

Pairing LLM acceleration with strict architectural specs and automated test validation

Markdown Spec

Spec & BDD Drafting

Define feature requirements as structured specifications and Gherkin scenarios. Each spec becomes the single source of truth for what the system must do.

specs/inventory-alert.spec.md 
# Spec: Stock Alert Threshold Engine
- Constraint: Evaluate stock every 60s
- Alert: If units < 10, dispatch event to RabbitMQ
- Redundancy: Fallback to SQS if RabbitMQ fails
- Security: Sanitized JWT payload required

TDD Suite

TDD Test Generation

AI generates comprehensive unit and integration test suites following TDD principles. Tests are written before production code, defining the expected behavior.

tests/unit/stockAlert.spec.ts 
describe('StockAlert Workflow', () => {
  it('dispatches RabbitMQ event when stock drops below threshold', async () => {
    const queue = new MockQueue();
    const svc = new StockAlertService(queue);

    expect(queue.publishedEvents).toHaveLength(1);
  });
});

Generated Production Code

Production Code Generation

AI writes production code that satisfies all generated tests. The Red-Green cycle is automated: generate tests → generate code → verify all pass.
