AvsSimulator

class lsst.ts.fiberspectrograph.AvsSimulator

Bases: object

Mock a libavs Avantes spectrograph connection; mocks enough of the AVS_* C free functions from libavs.0.2.0 to allow connecting and disconnecting, getting status, and starting/stopping exposures.

This configures the mock for a “no error conditions” use case, with all methods behaving as if one device is connected and behaving.

Methods Summary

start([testCase])	Start the simulator by patching the spectrograph library.
stop()	Disable the patched mock library.
