@agritheory in test cases, which workstation we have to set in alternative workstation. can we assign some random workstation in operation alternative workstation?

@viralkansodiya I don't think "random" is a good idea, but I think it'll be good to set up the alternative workstations in [tests/fixtures.py](https://github.com/agritheory/inventory_tools/blob/version-14/inventory_tools/tests/fixtures.py#L60) and [tests/setup.py](https://github.com/agritheory/inventory_tools/blob/version-14/inventory_tools/tests/setup.py#L186). We don't need it for all workstations, but one or two to be able to create a test or two and configure it would be good.
