Expected behavior

I expected to see no-self-argument when a method has *args or **kwargs rather than no-method-argument as the latter is quite confusing as the method does have arguments.

I think that makes sense. Thank you for reporting it.

It would also be a nice to have that the wording for both no-method-argument and no-self-argument include the method name, that is

Method has no argument (no-method-argument)
Method should have "self" as first argument (no-self-argument)

to be

Method NAME has no argument (no-method-argument)
Method NAME should have "self" as first argument (no-self-argument)

Yeah, having the name of the method would definitely be better for CLI use. (it's probably not the case because in IDE you know the name: it's the function you're hovering)
