API

class ophyd_async.tango.testing.ExampleStrEnum

Bases: ophyd_async.core.StrictEnum

All members should exist in the Backend, and there will be no extras.

class ophyd_async.tango.testing.OneOfEverythingTangoDevice(cl, name)

Bases: tango.server.Device

Device class for the high-level API.

All device-specific classes should inherit from this class.

add_scalar_attr(name: str, dtype: str, initial_value: Any)

long_string_cmd(arg)

Echo command for DevVarLongStringArray.

double_string_cmd(arg)

Echo command for DevVarDoubleStringArray.

void_cmd()

Command for DevVoid.

add_array_attrs(name: str, dtype: str, initial_value: ndarray)

add_scalar_command(name: str, dtype: str)

add_spectrum_command(name: str, dtype: str)

initialize_dynamic_attributes()

Method executed at initializion phase to create dynamic attributes. Default implementation does nothing. Overwrite when necessary.

.. note:: This method is only called once when the device server starts, after init_device(), but before the device is marked as exported. If the Init command is executed on the device, the initialize_dynamic_attributes() method will not be called again.

float_to_bool_cmd(value: float) → bool

Command with float input and bool output (different in/out types).

write(attr)

class ophyd_async.tango.testing.TangoDeviceInfo

Bases: typing.TypedDict

Configuration for a single Tango device instance for MultiDeviceTestContext.
