Immune to psychology and leadership-based tests

This question came up in my last game, and after looking on the internet i couldn't come up with a reasonable answer. So please tell me: Do you pass leadership-based tests (not counting rout tests) automatically if you are immune to psychology?
So would an Ulfwerenar be immune to the spell lure of chaos from the chaos rituals?

I lean towards no but would like to get a confirmation (or be corrected).

Greetings

Hi Exterminans.

Many leadership tests are caused by psychology, but not all. Being immune to psychology will make you immune only to the effects of anything in the Psychology chapter of the rulebook except for the rout test, which is specifically excluded. You can take a look at the darksouls from the Cult of the Possessed, they have a special rule stating that they pass every leadership test automatically, which is something quite different.

In case you need it, +1 to what Master Spark said.

So what i already thought but was unsure about. Thanks to both of you
