@ -34,15 +34,8 @@ Rule-based inspection
All rule-based inspections are using pre-defined actions written on python, for
now they defined in "steps.py" file in the directory:
ostack_validator/inspections/lettuce. As you can see they are based on lettuce
framework - bdd framework for python.
Store and reuse rules
---------------------
You can store your rules wherever you want and add it through the UI or simply
putting it in directory ostack_validator/inspections/lettuce with name like
this: *.feature. The main requirement is that all you actions in those files
must be written according to the rules in steps.py.
Also you can expand the rules definition by adding your own steps.py. As example:
framework - bdd framework for python.
You can expand the rules definition by adding your own steps.py. As example:
#This decorator is for defining step for using them in the scenario.
@step(r'Nova has "(.+)" equal to "(.*)"')

New methods can use 2 classes from the inspections framework:
ostack_validator.model and ostack_validator.common. There are you can find many
adapters to the services configuration data and all additional information
collected from OpenStack nodes. After that you can use you brand new rule in
the scenarios as described above.

information collected from OpenStack nodes. After that you can use you brand
new rule in the scenarios as described above. In common.py you can find
Inspection, Issue, Mark, Error and Version classes for your comfortability in
rule defining. Model.py contains Openstack model based on configuration
schemas.
