found assertion on exception {name} in except block, use pytest.raises() instead

Examples

Bad code:

def test_foo():
    try:
        1 / 0
    except ZeroDivisionError as e:
        assert e.args

Good code:

import pytest

def test_foo():
    with pytest.raises(ZeroDivisionError) as e:
        1 / 0
    assert e.value.args

to avoid the situations when the test incorrectly passes because exception was not raised
