The test case is: class Test1: """" Test Class 1 """ def __init__(self): self.a = 1 def test_func1(self): # Foo pass def test_func2(self): # Foo pass And the complaint is that `M-x hs-minor-mode RET' `M-x hs-hide-level RET' doesn't hide all the functions. But is does for me in Emacs 28, so I'm going to go ahead and guess that this has been fixed in the years since this was reported. If this is still a problem, please respond to the debbugs address and we'll reopen.
