… + update stale mocks to nested coils API
There was a problem hiding this comment.
Pull request overview
This PR updates the test suite to match the refactored coils/field API (coil quantities now accessed via field.coils.*) and fixes a real bug in BiotSavart_from_gamma where read-only computed properties were being assigned and could recurse.
Changes:
- Update test mocks/usages to the new nested
field.coilsstructure and adjustBiotSavartinitialization assertions accordingly. - Switch coil length/curvature tests to use a real
CoilsPyTree to work with JAX@jit. - Fix
BiotSavart_from_gammato use private backing attributes (_coils_length, etc.) for cached properties.

I think I agree here. Is it impossible to fix? Seems like we are just hiding important tests. You can ask @eduardolneto for help if needed.

I would say this should indeed be marked as an expected fail, since we eventually want to replace the objective_functions.py file, or at least significantly reduce it. This way, we won't forget about it.

Seems like the GitHub workflow file only runs CI/CD actions when pull requests are made to main (or there are pushes to main). Can you make it so that it always runs for all pull requests? Then we can see how tests run in this pull request directly. |

Why not DummyCurves and DummyCoils?

Remove self.coils_length, self.coils_curvature, and self.coils_gamma. Should be accessed through self.coils.

Remove, we already have DummyCoilsObj doing exactly the same...

This is the DummyInnerCoils we already have
…urves, remove unused patch, run CI on all PRs
Fixes the failing CI tests so the build passes.
Most of the failures were stale test mocks that no longer matched the
refactored API. The code now nests coil quantities under field.coils
(field.coils.length, biot_savart.coils.currents, and so on), but the mocks
still used the old flat attributes. Updated them to match.
One failure was a real bug in BiotSavart_from_gamma: coils_length,
coils_curvature, r_axis, and z_axis are read-only properties, but init
was assigning to the public names, and the coils_length getter referenced
itself and recursed infinitely. I fixed this by using private backing attributes
(_coils_length, etc.), the same way _gamma_dash already works in that class.
