pytc.solver.test.test_isdf_xtc_ccsd¶
Tests for the factorized-dispatch solver class isdf_xtc_ccsd.RCCSD.
These tests EXECUTE the class’s own seams on a tiny synthetic case so that a missing or mis-signed dependency (an import target that exists only in a diagnostic harness, a renamed attribute) fails in the suite rather than in production. Identity checks alone cannot catch that class: they prove which code would run, not that everything it calls exists.
Classes
The dispatch seam's structure, pinned so a refactor fails loudly. |
|
Call _factorized_state() for real: extraction, fit, caching, guards. |
|
The whole-X host preload fires on the materialized parent but is suppressed on the factorized subclass, with identical X content. |
Functions
Minimal xtc_obj attribute surface consumed by the factorized state. |
