1. Introduction

1.1. Overview

This document contains machine readable test vectors for several Preparation, Enforcement, and Comparison of Internationalized Strings (PRECIS) [RFC8264] profiles.

Two sets of vectors exist for profiles of the base classes. The first set tests the enforcement step. It takes the form of a table that contains an input string, an output string and an optional error. If the error column has a value of "ctx" it indicates that the context rule was violated, "empty" means that an empty string was disallowed, "rune" means that a disallowed code point (rune) was encountered, and "bidi" indicates that the BIDI Rule was violated. The second set tests the PRECIS comparison step. It takes the form of a table that contains two strings, a boolean that is TRUE if the two strings should be considered equal and FALSE otherwise, and an optional comment.

Vectors for inclusion of code points in the IdentifierClass and FreeformClass are not included. A complete list of valid inputs and Outputs for the derived property algorithm specified in [RFC8264] can be found in the IANA "PRECIS Derived Property Value" registry.

1.2. Terminology

Many important terms used in this document are defined in [RFC8264], [RFC6365], and [Unicode].

2. Test Vectors

2.1. Methodology

The test vectors in this document have been verified by three independent implementations. An implementation that concurs with the results provided in this document should be interoperable with other implementations.

Input and output strings are expressed as UTF-8 and hexidecimal encoded byte strings.

2.2. Enforcement Tests

2.2.1. Basic

2.2.2. ctx 1

2.2.3. ctx 2

2.2.4. ctx 3

2.2.5. ctx 4

2.2.6. ctx 5+6

2.2.7. ctx 7

2.2.8. ctx 8+9

2.2.9. Nickname

2.2.10. OpaqueString

2.2.11. UsernameCaseMapped

2.2.12. UsernameCasePreserved

2.3. Comparison Tests

2.3.1. Nickname

3. IANA Considerations

This document requires no interaction with the Internet Assigned Numbers Authority (IANA).

4. Security Considerations

This document is intended to provide test vectors for the PRECIS framework and its profiles. No assertion of the security of the PRECIS framework or its profiles for any particular use is intended. The reader is referred to [RFC8264] for a discussion of the general security of the PRECIS framework.
