15 failing tests fail when running make test on a Mac

[rtindru]

Issue

A total of 15 tests fail when I run make test on the docker container running on a Mac

Hypothesis

Some of these tests seem to be failing due to encoding issues.
My guess is that the mismatch in the underlying filesystem (docker says linux, but I run Mac) could be the root cause.
I noticed that underlying the code for these tests does check for the system architecture, but I am out of my depth here to be 100% sure.
Ex: test_non_ascii ->

cinder/Lib/test/test_cmd_line_script.py

Lines 531 to 542 in 7ccf3d8

	def test_non_ascii(self):
	# Mac OS X denies the creation of a file with an invalid UTF-8 name.
	# Windows allows creating a name with an arbitrary bytes name, but
	# Python cannot a undecodable bytes argument to a subprocess.
	if (support.TESTFN_UNDECODABLE
	and sys.platform not in ('win32', 'darwin')):
	name = os.fsdecode(support.TESTFN_UNDECODABLE)
	elif support.TESTFN_NONASCII:
	name = support.TESTFN_NONASCII
	else:
	self.skipTest("need support.TESTFN_NONASCII")

Steps to reproduce

• Get a Mac 💻
• Checkout code and build using the instructions in the ReadME
• Run make test

System information

• MacBook Pro (16-inch, 2019)
• OS version: 11.2.3
• Darwin Kernel Version 20.3.0
