Using AI Agents to Auto-Create Test Documentation from Code

The Problem

Test documentation is often:

• Outdated

• Manually written

• Ignored

AI agents can generate living test documentation directly from code.

What the AI Agent Generates

• Functional specs

• API contracts

• Validation rules

• Error scenarios

• Assumptions & constraints

Workflow

1. Agent scans controllers, services, DB models

2. Extracts rules and flows

3. Generates:

   • Test strategy

   • Module-wise test scope

   • Known risk areas

Cursor Implementation

• Ask Cursor to:

  “Generate functional documentation for this service for QA usage”

• Save output as:

  • feature-overview.md

  • test-scope.md

Why This Is Powerful

Docs never go stale because they are regenerated from code.
