Function Generation

// Type comment and let Amazon Q generate
// Function to validate email address
function validateEmail(email) {
    const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
    return emailRegex.test(email);
}

API Endpoint Creation

# Generate Flask API endpoint
# POST endpoint to create user
@app.route('/users', methods=['POST'])
def create_user():
    data = request.get_json()
    user = User(
        name=data['name'],
        email=data['email']
    )
    db.session.add(user)
    db.session.commit()
    return jsonify({'id': user.id}), 201

Unit Test Generation

// Generate Jest tests for function
describe('validateEmail', () => {
    test('should return true for valid email', () => {
        expect(validateEmail('test@example.com')).toBe(true);
    });

    test('should return false for invalid email', () => {
        expect(validateEmail('invalid-email')).toBe(false);
    });
});
