Make a test that creates an NTNDArray using p4p #645

Open coretl opened 1 week ago

coretl commented 1 week ago

At the moment we use QSRV to do testing for PVA, but that can't do tagged unions. We should specifically test Signal[np.ndarray] using a p4p server with a StaticProvider, with a single SharedPV of type NTNDArray

Acceptance Criteria

The np.ndarray test passes, and https://github.com/bluesky/ophyd-async/blob/3d9f508d38c3db513c620971a66c4fc6437ce60b/src/ophyd_async/epics/core/_p4p.py#L190 can be removed in favour of a line with U instead of v in it
