Specification analysis (Static testing)

Observations:

The following behaviors are not completely defined by the current OpenAPI specification:

• Minimum and maximum length for name.
• Minimum and maximum length for email.
• Whether an empty name is allowed.
• Whether an empty UserUpdate object is allowed.
• Expected status code and error format for validation errors.
• Expected behavior for malformed or empty path parameters.
• Whether duplicate email addresses are allowed.
• Authentication and authorization requirements.
• Pagination/filtering requirements for GET /users.

Requirements to clarified

Expectations:
The user name must have a defined minimum and maximum length.

Status: Undefined

REQ-USER-002 — Duplicated email
