Add parity test comparing FastVideo's SAAudioVAEModel against the official daVinci-MagiHuman SAAudioFeatureExtractor.decode() path. The sibling test_magi_human_sa_audio_parity.py validates against Diffusers AutoencoderOobleck; this test validates against the upstream repo's custom integration layer, which rebuilds AudioAutoencoder from model.pretransform.config and filters pretransform.model.* weights. Test passes at machine-eps (diff_max=0, diff_mean=0) in fp32, confirming FV's SAAudioVAEModel is bit-identical to the official decode path. This rules out the audio VAE as a contributor to OQ-6 (pipeline compounding). Requires the daVinci-MagiHuman upstream clone and the gated stabilityai/stable-audio-open-1.0 repo. Skips cleanly when either is absent.
Local Tests
Local-only parity, smoke, and component tests for FastVideo model ports. They compare FastVideo against the official reference implementations and are skipped in CI; run them locally on a single GPU (or CPU where noted).
For the CI-backed test suite, see fastvideo/tests/.
Layout
Tests are organized by model family, one directory per port. Each family
directory follows the layout produced by the
add-model-prep skill:
tests/local_tests/<family>/
├── README.md # reference assets, setup, test inventory
├── __init__.py
└── test_<family>_<component>_*.py
Families
| Family | Workload | Dir |
|---|---|---|
| Hunyuan GameCraft | T2V / I2V | gamecraft/ |
| GEN3C | T2V | gen3c/ |
| Kandinsky-5 | T2V | kandinsky5/ |
| LTX-2 | T2V (+ audio) | ltx2/ |
| Stable Diffusion 3.5 | T2I | sd35/ |
| Stable Audio Open 1.0 | T2A | stable_audio/ |
| Wan2.2 | I2V | wan22/ |
Running a family
pytest tests/local_tests/<family>/ -v -s
See each family's README.md for setup (clones, weights, env vars, gated
tokens) and the per-component parity coverage.
Adding a new family
Run the add-model-prep
skill from the FastVideo repo root. It scaffolds the family directory and
README.md and stages reference clones + weights. (In-progress ports may also
add a PORT_STATUS.md from the same skill template; remove it once the port
lands.)
