The following test fails because because `seq1 == seq2` returns a (boolean)
NumPy array
whenever either seq is a NumPy array.
import unittest
import numpy as np
unittest.TestCase().assertSequenceEqual([1.,2.,3.], np.array([1.,2.,3.]))
I expected `unittest` to rely only on features of a `collections.abc.Sequence`,
which based on https://docs.python.org/3/glossary.html#term-sequence,
I believe are satisfied by a NumPy array. Specifically, I see no requirement
that a sequence implement __eq__ at all much less in any particular way.
In short: a test named `assertSequenceEqual` should, I would think,
work for any sequence and therefore (based on the available documentation)
should not depend on the class-specific implementation of __eq__.
Is that wrong?
Thank you, Alan Isaac
