Developers can use ``fake-hardware`` hardware-type to mock out nodes for
testing without those nodes needing to exist with physical or virtual hardware.
Scale testing
-------------
The ``fake`` drivers have a configurable delay in seconds which will result in
those operations taking that long to complete. Two comma-delimited values will
result in a delay with a triangular random distribution, weighted on the first
value. These delays are applied to operations which typically block in other
drivers. This allows more realistic scenarios to be arranged for performance and
functional testing of an Ironic service without requiring real bare metal or
faking at the BMC protocol level.

Adoption

Some OpenStack deployers have used ``fake`` interfaces in Ironic to allow an
