This topic has been raised 3 years ago but it provided no answer.
I want to be able to unittest an Inventory plugin I am developing.
Basically, all I need is a way to execute the parse(self, inventory, loader, path, cache=True) method of my class extending BaseInventoryPlugin, Constructable.
I have been able to come up with something simple that was working:
def test_parse_with_valid_config(self):
source = os.path.join(os.getcwd(), ‘test/valid_test_conf.yml’)
loader = DataLoader()
inventory = InventoryData()
inventory.current_source = source
plugin = InventoryModule()
trick to be able to invoke the parse function only
plugin._redirected_names = [‘myplugin’]
plugin._load_name = u’odewe’
end trick
plugin.parse(inventory, loader, inventory.current_source)
#assertion on constructed inventory can be implemented here.
But since I started to use options to pass variables, this doesn’t cut it anymore.
I’ve tried debugging all I can to see how option were set but it seems impossible to set them without calling the cli itself.
AFAIK, I have to call the cli with subprocess this way:
subprocess.call([sys.executable, os.path.join(os.path.dirname(sys.executable), “ansible-inventory”), ‘-i’, ‘config.yml’, ‘–playbook-dir’, ‘.’, ‘–list’])
but then I have no way to access the internal inventory produced.
All I’m left with now would be to dump the result to a file and build python objects from the file to be able to make assertions, but that would really be ugly.
Kind regards
