How to handle B015 within pytest.raises blocks

Often when defining custom objects we end up testing that the __eq__ raises a particular error for unsupported comparisons. In practice, this means we have an unused comparison that triggers the B015 rule—see the MWE below. I wonder if there's a recommended way to get around this (without suppressing B015 altogether), or whether it could say be disabled within a with pytest.raises context.

Minimal working example:

# B015.py
import pytest


class MyClass:
    def __init__(self, x):
        self.x = x

    def __eq__(self, other):
        if not isinstance(other, MyClass):
            raise TypeError(f"Cannot compare with {type(other)}")
        return self.x == other.x


a = MyClass(5)
b = MyClass(5)
c = MyClass(4)

assert a == b
assert a != c
with pytest.raises(TypeError):
    a == a.x

$ flake8 B015.py 
B015.py:21:5: B015 Result of comparison is not used. This line doesn't do anything. Did you intend to prepend it with assert?

Start by reproducing the MWE in B015.py with the reported flake8 command, then inspect how B015 identifies unused comparisons and whether pytest.raises context is available to that analysis. Done means establishing a documented workaround or a clearly scoped behavior for comparisons inside pytest.raises blocks, with tests covering the chosen behavior.
