@Snooz82 - I would also appreciate such option!

Could you clarify the need in a bit more detail? Run Keyword doesn't do much logging on INFO or DEBUG level even now.

@pekkaklarck I am not sure if this is the case, but code like this:

from robot.libraries.BuiltIn import BuiltIn

class example:
    def custom_kw(self, a, b):
        BuiltIn().run_keyword("Should Be Equal", a, b)

*** Settings ***
Library    example.py


*** Test Cases ***
A
    Custom Kw   9    9

Produces Log like this (where should be equal is child of custom kw)

Yes exactly.

I had this issue several times.
I would propose to have some kind of possibility to "mute" the logger.
I know that there are monkey patching possibilities but this is ugly and robot should support this directly.

run_keyword

I've got the same result when using Run Keyword. However, I don't really understand why don't you just use like this instead.

from robot.libraries.BuiltIn import BuiltIn

class example:
    def custom_kw(self, a, b):
        BuiltIn().should_be_equal(a, b)

This way it omits the log as you proposed.

I don't think changing BuiltIn.run_keyword is a good idea, but we can consider better APIs that library keywords can use to run other keywords. There are already some related issues in RF 8 scope and I add this there as well.
