		1		"""This is a mock krita module for Python unit tests.
		2
		3		This module returns a mock object for any attribute name and thus
		4		prevents any errors surrounding the krita module in unit tests. This
		5		makes it possible to write unit tests for Krita-independent code
		6		units.
		7
		8		Caveats:
		9
		10		Will only work with proper imports:
		11
		12		import krita
		13		krita.Krita.instance() # no-op on a mock object
		14
		15		Not with wildcard imports:
		16
		17		from krita import *
		18		Krita.instance() # error
		19
		20		(Wildcard imports should be avoided anyway.)
