ophyd_async.core.MockSignalBackend

class ophyd_async.core.MockSignalBackend(datatype: Type[T] | None = None, initial_backend: SignalBackend[T] | None = None)

Bases: SignalBackend[T]

Methods

connect
datatype_allowed	Check if a given datatype is acceptable for this signal backend.
get_datakey
get_reading
get_setpoint	For a soft signal, the setpoint and readback values are the same.
get_value
put
set_callback
set_value
source

Attributes

datatype	Datatype of the signal value
put_mock
put_proceeds

datatype: Type[T] | None = None

Datatype of the signal value

source(name: str) → str

async connect(timeout: float = 10.0) → None

property put_mock: AsyncMock

property put_proceeds: Event

async put(value: T | None, wait=True, timeout=None)

set_value(value: T)

async get_reading() → Reading

async get_value() → T

async get_setpoint() → T

For a soft signal, the setpoint and readback values are the same.

async get_datakey(source: str) → DataKey

abstract classmethod datatype_allowed(dtype: type)

Check if a given datatype is acceptable for this signal backend.

set_callback(callback: Callable[[Reading, T], None] | None) → None
