haybarn-unittest 1.5.4rc1

Haybarn unittest — the DuckDB unittest test runner for the Haybarn engine, runnable via uvx haybarn-unittest.

haybarn-unittest on PyPI

The Haybarn test runner — DuckDB's unittest binary, rebranded — runnable directly from PyPI:

uvx haybarn-unittest --test-dir . --list-tests
# or
pipx run haybarn-unittest --test-dir path/to/extension test/sql/my_test.test

What this is

haybarn-unittest is a binary-distribution package. Each PyPI wheel embeds the pre-built haybarn-unittest binary for one platform, tagged so pip / uv auto-select the correct one:

• manylinux_2_28_x86_64 — glibc-based Linux on x86_64
• manylinux_2_28_aarch64 — glibc-based Linux on aarch64
• musllinux_1_2_x86_64 — Alpine / musl Linux on x86_64
• musllinux_1_2_aarch64 — Alpine / musl Linux on aarch64
• macosx_11_0_x86_64 — macOS 11+ on Intel
• macosx_11_0_arm64 — macOS 11+ on Apple Silicon
• win_amd64 — 64-bit Windows

The Python shim (haybarn_unittest:main) os.execvs into the bundled binary, so signals and exit codes propagate naturally.

It runs SQL logic (.test) files against the Haybarn engine — point it at your own test directory with --test-dir. The binary launches from any working directory; --test-dir <dir> tells it where your tests live.
