Nornir will keep track of hosts that failed and won’t run future tasks on them: In [9]: from nornir.core.task import Result def hi ( task ): return Result ( host = task . host , result = f " {task.host.name} : Hi, I am still here!"
No need to restructure your project, having tests outside your source is good practice! If both src and tests have a __init__.py, and assuming you're writing traditional unittest.TestCase tests, you can leverage the standard unittest module to discover and run your tests with a simple python -m unittest from the top-level directory. –

The main implication of this for Nornir end-users is that certain group-filter patterns no longer work. For example, in Nornir 2.X, you used to be able to do group filtering the following way: # Nornir 2.X example nr = nr. filter ( groups= [ "nxos" ])
30.05.2018 · The first thing you need before you can use Nornir is an inventory. In its most basic form, a Nornir inventory is a Python dictionary containing one or more hosts.
