🧪 QA Architecture & Testing Strategy Report

📋 Executive Summary

This report presents a comprehensive, independent testing strategy for the analyzed codebase. The analysis identified 7 modules across 2 languages with 0 frameworks detected. The zero-trust approach assumes 0% current test coverage, requiring full test strategy development from scratch.

Highest Risk Areas: High complexity module with risk score 100

Architecture Pattern: serverless

Entry Points:

🔲 Black Box Testing

Independent Baseline: Test functionality without internal code knowledge, treating the application as a black box with inputs and outputs.

Vulnerability & Risk Assessment: The 0 entry points represent the primary black-box testing surface. Focus on 5 authentication modules and 5 database interaction points.

Strategy: Equivalence partitioning, boundary value analysis, decision table testing based solely on requirements and API contracts.

From-Scratch Test Cases

# For each API endpoint in the application:
# Test valid, boundary, and invalid inputs
POST /api/endpoint {"field": "valid_value"}  # Expect 200
POST /api/endpoint {"field": ""}            # Expect 400 - empty
POST /api/endpoint {}                      # Expect 400 - missing field

# Test edge cases and boundaries
GET /api/users?page=0    # Expect 400 or redirect
GET /api/users?page=1    # Expect 200 - first page
GET /api/users?page=MAX  # Expect 200 or 404 - last page
GET /api/users?page=MAX+1 # Expect 404 or empty

# Complex business logic combinations
# Table: Authentication + Authorization
User Authenticated + Has Permission = Access Granted 200
User Authenticated + No Permission = 403 Forbidden
No Authentication = 401 Unauthorized
Invalid Token = 401 Unauthorized
