14.14Schema validation

Suppose OpenAPI says response:

{
  "customerId": "string",
  "salesforceId": "string",
  "success": true
}

Your tests should validate the response against the OpenAPI schema, not only individual fields.

Conceptually:

response
 ↓
OpenAPI validator
 ↓
schema valid?

This catches accidental changes such as:

salesforceId
→ salesForceId

or:

boolean success
→ string "true"
