It silently does nothing

What do you mean by this? From the code, it seems it silently creates the file. Is that the behavior you're seeing?

[mvz]

This is officially documented bad behavior:

aruba/features/03_testing_frameworks/cucumber/steps/filesystem/append_to_file.feature

Lines 29 to 43 in 996d631

	Scenario: Append to a non-existing file
	Given a file named "features/non-existence.feature" with:
	"""
	Feature: Existence
	Scenario: Existence
	Given a file named "foo/bar/example.txt" does not exist
	When I append to "foo/bar/example.txt" with:
	\"\"\"
	this was appended
	\"\"\"
	Then the file named "foo/bar/example.txt" should contain:
	\"\"\"
	this was appended
	\"\"\"
	"""

Steps to resolve this:

• In 1.x: Deprecate silent creation of the file
• In 2.0: Remove silent creation of the file

Sounds perfect. Good solution, definite thumbs up from me.
