I think may be helpful to add an integration test for this case, when the skip flag is inherited from include

[rodrigorfk]

Thanks for your suggestion @denis256 , I've updated the TestApplyAllSkipTrue integration test to cover this scenario as well, it was already using an partial terragrunt file there with a skip = true defined, so now one of the child modules is inheriting the skip and the other is overwriting it.

[rodrigorfk]

Thanks for publishing the failed tests here @denis256 and sorry for not catching them initially, I've fixed them.

[rodrigorfk]

Hi @denis256 , could you please share the reason why the test_signing job failed? looking into it's definition it seems to only be related to binary signing and not really related to the specific change I am doing in this PR, right? thanks in advance.

[denis256]

Hi,
it is an internal issue with Apple... I hope will be fixed soon
