I don't think it's necessary to put these tests in a separate file.
I would just add them in the existing test_dahuffman.py file
Maybe move the tests and fixtures inside a class, e.g. TestEndOfFileSymbol. I'm guessing you used a separate file to keep the fixtures away from existing tests, but you can also achieve that by scoping them to a single class

I feel this construct of three fixtures is a bit convoluted and misses some useful things to test against.
I would just make a straight list of values to use, e.g.
[
b"\0",
b"abc",
"abc",
0,
100,
-1000,
False,
True,
None,
[],
(),
{},
[-100, 0, 10],
(-100, 10),
_EndOfFileSymbol()
]

maybe also test equality _EOF == _EndOfFileSymbol()

What I meant in a previous comment was pytest allows you to define the fixture as a method of TestEndOfFileSymbol (instead of a module level function), which makes it available only to other methods of that class

I would also assert for !=, and maybe just put everything in same test function to keep it simple:
assert _EOF < to_compare
assert _EOF <= to_compare
assert to_compare > _EOF
assert to_compare >= _EOF
assert to_compare != _EOF
assert not (to_compare == _EOF)
