Test data

The tests read files under testdata/. Nothing in that tree is required at runtime.

Wire cases

testdata/kiln-v2-cases.json has 46 accept and reject cases for Kiln wire v2. The cap recorded in the file is 16777216. Each case has hex input, expect of accept or reject, and an error name when it rejects.

Expect	What a passing run means
accept	Decode the hex, match decoded when it is present, and re-encode the same bytes.
reject	The decoder returns the case's error name.

Cases whose id is about a hostile count also require the allocation counter to stay at zero. bash scripts/run-tests.sh compiles build/kiln-tests and runs that program on the file.

Schemas

File	What it generates
testdata/schema/point.json	Point, with optional label.
testdata/schema/message.json	Message and nested Meta.
testdata/schema/batch.json	Batch, with f32 and i64 lists, bools, and binary strings.

bash scripts/check-generated.sh writes those files again and diffs them against tests/generated. A drift fails the check.

Oracle

testdata/reference/kiln_ref.py encodes Frozen values for the tests. The C codec decodes those bytes and encodes them again. The set includes Point, Message, lists, optionals, dicts, framed values, a negative zero, and a quiet NaN payload. The reference is not linked into the library.
