test: lock down WeakDataset json round-trip (paired with PyAutoArray fix) - #555
Merged
Conversation
Regression test for the failure mode that surfaced in PR #525 — al.from_json on a serialised WeakDataset previously crashed with: TypeError: VectorYX2DIrregular.__init__() missing 1 required positional argument: 'values' The library-side fix lives in PyAutoArray (a `values` property on VectorYX2DIrregular). This test asserts the full simulator → write → load path, including subclass preservation — loaded.shear_yx returns as ShearYX2DIrregular, not the base class — plus matching shear values, grid positions, and noise map. Refs issue #554. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Adds a regression test that exercises the full
al.output_to_json→al.from_jsonround-trip forWeakDataset. The original failure (surfaced in PR #525 / workspace #188) was aTypeError: VectorYX2DIrregular.__init__() missing 1 required positional argument: 'values'raised insidedictable.from_dict. The library-side fix lives in PyAutoArray; this PR locks down the end-to-end behaviour at theWeakDatasetlevel, including subclass preservation (loaded.shear_yxcomes back asShearYX2DIrregular, not the base class).Paired with: PyAutoLabs/PyAutoArray#342
Closes #554.
