Functions#

check_remote_data_size(widget, plot_name, num_elements)

Check if the remote data has the correct number of elements.

Module Contents#

class DMMock(*args, **kwargs)#
_get_redis_device_config() → list[dict]#

Mock method to emulate DeviceManager._get_redis_device_config.

add_devices(devices: list)#

Add devices to the DeviceContainer.

Parameters:

devices (list) – List of device instances to add.

get_bec_signals(signal_class_name: str)#

Emulate DeviceManager.get_bec_signals for unit-tests.

For “AsyncSignal” we list every device whose readout_priority is ReadoutPriority.ASYNC and build a minimal tuple (device_name, signal_name, signal_info_dict) that matches the real API shape used by Waveform._check_async_signal_found.

Parameters:

  • name (str) – The name of the device.

  • info (dict, optional) – The device info dictionary. Defaults to None.

  • parent ([type], optional) – The parent object. Defaults to None.

  • signal_info (dict, optional) – The signal info dictionary. Defaults to None.

  • class_name (str, optional) – The class name of the device. Defaults to None. If None, the class name is inferred from the class of the object.

class FakeDevice(name, enabled=True, readout_priority=ReadoutPriority.MONITORED)#

Bases: bec_lib.device.Device

Fake minimal positioner class for testing.

move(value, relative=False)#

Simulates moving the device to a new position.

read(cached=False)#

Reads the device.

Parameters:

  • cached (bool, optional) – If True, the cached value is returned. Defaults to False.

  • use_readback (bool, optional) – If True, the readback value is returned, otherwise the read value. Defaults to True.

  • filter_to_hints (bool, optional) – If True, the readback value is filtered to the hinted values. Defaults to False.

Returns:

The device signals.

Return type:

dict
