Test data

The tests read schemas and bytes from testdata/ and from literals in the test programs. Nothing in this tree is named a fixture.

Schemas

File	What it covers
testdata/avsc/demo.avsc	Nested record, enum, fixed, array, map, and unions.
testdata/avsc/longlist.avsc	Recursive next field. Also the codegen sample.
testdata/avdl/demo.avdl	IDL protocol, imports, defaults, and a skipped message.
testdata/avdl/extra.avdl	import idl.
testdata/avdl/from_schema.avsc	import schema.
testdata/avpr/demo.avpr	JSON protocol. types are loaded. messages are ignored.

parseAvdl of demo.avdl and parseAvsc of demo.avsc produce the same CRC-64-AVRO fingerprint for demo.Document.

Bytes

testdata/golden/ocf_null.bin and testdata/golden/ocf_deflate.bin are object container files written by Python avro 1.12 for the same two records. The deflate block is raw DEFLATE from DataFileWriter, which uses zlib with a negative window. The test decodes both files and checks the field values. It does not compare deflate bytes to a particular compressor.

Primitive and record goldens live next to the tests as hex. They were produced with Python avro.io.BinaryEncoder for null, boolean, int, long, float, double, bytes, string, array, map, enum, fixed, union, and a nested record. A negative array block (count = -2, size 2, items 1 and 2) is decoded by hand. Truncated strings and bad UTF-8 must fail.

zig build test does not need Python. Python is only the program that originally wrote those bytes.

Generated samples

tests/generated/ holds Zig emitted by gld-avrogen-zig for LongList, demo.M, mutual A/B, and Node. tests/generated_test.zig encodes and decodes them. scripts/check-generated.sh regenerates LongList.zig and fails on a diff.
