Map Route Changes for Testing

Purpose

Turn “routes changed in this work” into an actionable test inventory so you can efficiently smoke test what matters.

When to use

Use this skill when:

• •You changed route files and need to identify what to test
• •You need to generate test cases for multiple endpoints quickly
• •You want a structured record to hand off for verification

Inputs

• •Source of truth for changes:
  • •version control diff/commit range
  • •PR file list
  • •local change list
• •Optional: additional route hints from the user (paths or modules)
• •Service routing configuration (prefixes, base path, API versioning)

Outputs

• •A deduplicated list of endpoints with:
  • •method
  • •path
  • •authentication requirement (best-effort)
  • •request shape notes
  • •response shape notes
  • •one valid payload example
  • •one invalid payload example
• •A short recommended test order (highest risk first)

Steps

1. •

   Collect changed route candidates

   • •Use version control to list changed files in the route layer.
   • •Include controller/service changes when they imply endpoint behavior changes.
2. •

   Resolve route base paths/prefixes

   • •Identify any global prefixes (e.g., /api, /v1) applied at the server level.
   • •Normalize endpoint paths to the final externally visible path.
3. •

   Enumerate endpoints

   • •For each route definition, capture:
     • •HTTP method
     • •path pattern
     • •required params/query/body
4. •

   Infer request/response shapes

   • •Prefer explicit validation schemas and DTOs as the source of truth.
   • •If schemas are absent, infer from controller/service usage and note uncertainty.
5. •

   Generate payload examples

   • •Provide:
     • •one valid example that should succeed
     • •one invalid example that should fail validation (or permission)
6. •

   Produce a structured inventory

   • •Output as JSON records (one per endpoint) or a table.
   • •Include “notes” fields where assumptions are made.
7. •

   Use the inventory to test

   • •Execute the happy path first for each endpoint.
   • •Verify persistence side effects for write endpoints.

Verification

• • Route inventory includes all changed endpoints
• • Each endpoint has method, path, and auth requirement documented
• • Valid payload examples conform to expected request shapes
• • Invalid payload examples trigger expected validation errors
• • Route prefixes match actual deployed paths
• • Inventory is usable for smoke testing (no missing critical info)

Boundaries

• •MUST NOT include real credentials or secrets in payload examples
• •MUST NOT skip authentication requirements in the inventory
• •MUST NOT assume route prefixes without verifying configuration
• •SHOULD NOT generate inventory for unchanged routes (focus on changes)
• •SHOULD NOT omit error cases (include at least one invalid example per endpoint)
• •SHOULD NOT hand off inventory without verifying at least one endpoint works

Included assets

• •Templates: ./templates/route-inventory.json provides a JSON shape for endpoint records.
• •Examples: ./examples/ includes a sample inventory entry.
