Module testing 

Test helpers for the XML engine.

These helpers are intentionally generic and domain-free. They centralize fixture paths, golden file comparisons, and parser/writer roundtrips so modules do not need to duplicate ad-hoc test utilities.

Structs

RoundtripResult

Result of parsing, serializing, reparsing, and serializing again.

XmlDiff

Compact, line-oriented diff for XML golden comparisons.

Constants

GOLDEN_DIR

Repository-relative directory for golden files.

XML_FIXTURES_DIR

Repository-relative directory for XML fixtures.

Functions

assert_compact_roundtrip

Parses XML, serializes it compactly, reparses it, and verifies stability.

assert_compact_roundtrip_with_config

Parses XML with explicit config, serializes compactly, reparses it, and verifies stability.

assert_document_matches_golden

Serializes a document using an explicit writer configuration and compares it to a golden file.

assert_matches_golden

Reads a golden file and compares it with actual XML output.

assert_xml_eq

Panics with a compact diff when two XML strings differ.

compare_xml

Compares XML strings while allowing a single final line ending in fixtures.

golden_path

Resolves a golden file path relative to the repository root.

parse_xml_fixture

Parses a fixture from tests/fixtures/xml.

read_golden

Reads a golden file from tests/golden.

read_utf8_file

Reads a UTF-8 file and maps filesystem errors to XmlError.

read_xml_fixture

Reads an XML fixture from tests/fixtures/xml.

repo_path

Resolves a path relative to the repository root.

xml_fixture_path

Resolves an XML fixture path relative to the repository root.
