qml.devices.tests.test_device

test_device(device_name, shots=0, skip_ops=True, flaky_report=False, pytest_args=None, **kwargs)

Run the device integration tests using an installed PennyLane device.

Parameters

• device_name (str) – the name of the device to test

• shots (int or None) – The number of shots/samples used to estimate expectation values and probability. If shots=None, then the device is run in analytic mode (where expectation values and probabilities are computed exactly from the quantum state). If not provided, the device default is used.

• skip_ops (bool) – whether to skip tests that use operations not supported by the device

• pytest_args (list[str]) – additional PyTest arguments and flags

• **kwargs – Additional device keyword args

Example

>>> from pennylane.devices.tests import test_device
>>> test_device("default.qubit.legacy")
