#1867: PropTest.kt

Tests Prop.extractProps() — the XML parser that extracts requested DAV property names from PROPFIND and sync-collection request bodies. Validates that property elements within <prop> or <d:prop> blocks are correctly identified, sorted alphabetically, and mapped to their PropType enum values.

The Prop class represents a single DAV property requested by a client. The static extractProps(xml: String): List<Prop> method parses WebDAV XML request bodies to determine what properties the client wants to retrieve.

Imports

• org.junit.jupiter.api.Assertions — JUnit 5 assertions
• org.junit.jupiter.api.Test — JUnit 5 test annotation

PropType Enum Values Covered

PropType	XML Element	DAV/CardDAV Purpose
CURRENT_USER_PRINCIPAL	<current-user-principal />	URL of the authenticated user's principal resource (RFC 5397)
CURRENT_USER_PRIVILEGE_SET	<current-user-privilege-set />	Privileges granted to the current user (RFC 3744)
DISPLAYNAME	<displayname />	Human-readable name of the resource (RFC 4918)
RESOURCETYPE	<resourcetype />	Whether the resource is a collection (RFC 4918)
GETCTAG	<cs:getctag />	Calendar Server collection tag for change detection (Apple extension)
GETETAG	<d:getetag />	HTTP entity tag for the resource (RFC 4918)
SYNCTOKEN	<sync-token />	Token for incremental collection synchronization (RFC 6578)

Test Scenarios

Scenario 1: Standard PROPFIND (XML namespace="DAV:")

Input is a PROPFIND request body using a default XML namespace (xmlns="DAV:") — elements are unprefixed. The test verifies:

• 4 properties are extracted
• Properties are sorted alphabetically by type: CURRENT_USER_PRINCIPAL, CURRENT_USER_PRIVILEGE_SET, DISPLAYNAME, RESOURCETYPE
• Each property's PropType is correctly identified

Scenario 2: sync-collection REPORT

Input simulates a sync-collection REPORT request (part of the RFC 6578 WebDAV Sync extension). The XML uses namespace prefixes (d:, cs:). The test verifies:

• 4 properties extracted (resourcetype, getetag, getctag, sync-token)
• Correct alphabetical sorting: GETCTAG, GETETAG, RESOURCETYPE, SYNCTOKEN
• Namespace-prefixed elements are correctly resolved

Parsing Logic (Inferred)

The extractProps method must:

1. Find the <prop> or <d:prop> element block within the XML
2. Extract child element names, stripping namespace prefixes
3. Match element names to PropType enum values
4. Sort results alphabetically by PropType
5. Return a List<Prop>

The alphabetical sorting is important for deterministic behavior — clients receive properties in a predictable order regardless of request XML element order.
