Hello,

How do I run a specific unit?

I would like to run: test/units/plugins/filter/test\_ipaddr.py

I tried

$ ansible-test units --tox --python 2.7 ipaddr

ERROR: Target pattern not matched: ipaddr

and

$ pytest test/units/plugins/filter/test\_ipaddr.py

This should work  
$ ansible-test units --tox --python 2.7 test/units/plugins/filter/test\_ipaddr.py
