   - Set `pipeline_class`, `required_input_params_in_call_signature` (params that must appear in `__call__`'s signature), and `batch_input_params` (params that get batched). Use the canonical sets in `..pipeline_params` where one fits, or an inline `frozenset([...])`.
   - Set `output_shape` — the per-sample output shape for `get_dummy_inputs()`, i.e. `(channels, height, width)` for an image pipeline and `(num_frames, channels, height, width)` for a video one. Assert against `self.output_shape` in pipeline-specific tests instead of repeating the literal.
   - Implement `get_dummy_components(...)` — build every sub-module from the **real classes** at tiny config, each preceded by `torch.manual_seed(0)`.
-  - Implement `get_dummy_inputs()` — **no `device` / `seed` arguments** (unlike the old style). Use `self.get_generator(0)` for the generator, keep sizes tiny, and set `output_type="pt"` so tests compare torch tensors directly with `assert_tensors_close` (no numpy round-trip). Remember `"pt"` images are `(batch, channels, height, width)`.

 - **Compose the config with one mixin per concern**, one test class each, named `Test<Pipeline>...`. Add only the mixins that apply:
   - `PipelineTesterMixin` — core save/load, dict-vs-tuple equivalence, batching, dtype/device, callbacks. Put pipeline-specific tests as methods on this class.
   - `MemoryTesterMixin` — CPU offload, group offload, layerwise casting.
