Based on the code snippet provided, it is not possible to say for sure whether there are bugs or code smells because the implementation of the RomanNumeral class is not provided. However, there are some observations and possible problems that can be pointed out:

1. The RomanNumeral class is not imported or defined in the code snippet, which would result in a NameError when trying to instantiate RomanNumeral(i) or RomanNumeral(s).

2. The test_should_create_roman_numeral_object_from_string test case expects the as_arabic() method to convert Roman numeral strings to their corresponding Arabic numeral integers. However, without implementation, we cannot verify that this method exists or works correctly.

3. The test_should_create_roman_numeral_object_from_int test case expects the as_roman() method to convert integers to their corresponding Roman numeral strings. Again, without implementation, we cannot verify that this method exists or works correctly.

4. There is a possible typo in the list of expected numbers for the Roman numeral representation of 900. It is listed as "DCCCC", but the correct Roman numeral for 900 is "CM".

5. The code does not follow the PEP 8 style guide for Python code, which recommends two blank lines before class definitions.

To resolve the potential issues and assuming the RomanNumeral class is correctly implemented elsewhere, the corrected code snippet would look like this:

import unittest

# Assuming the RomanNumeral class is defined in roman_numeral.py
from roman_numeral import RomanNumeral

class RomanNumeralTest(unittest.TestCase):
    def test_should_create_roman_numeral_object_from_int(self):
        actual_numerals = [RomanNumeral(i).as_roman() for i in [
            1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100,
            200, 300, 400, 500, 600, 700, 800, 900, 1000
        ]]
        expected_numerals = [
            "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X", "XX",
            "XXX", "XL", "L", "LX", "LXX", "LXXX", "XC", "C", "CC", "CCC", "CD", "D",
            "DC", "DCC", "DCCC", "CM", "M"  # Corrected "DCCCC" to "CM"
        ]
        self.assertListEqual(expected_numerals, actual_numerals)

    def test_should_create_roman_numeral_object_from_string(self):
        actual_numerals = [RomanNumeral(s).as_arabic() for s in [
            "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X", "XX",
            "XXX", "XL", "L", "LX", "LXX", "LXXX", "XC", "C", "CC", "CCC", "CD", "D",
            "DC", "DCC", "DCCC", "CM", "M"  # Assuming "CM" is the correct representation for 900
        ]]
        expected_numerals = [
            1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100,
            200, 300, 400, 500, 600, 700, 800, 900, 1000
        ]
        self.assertListEqual(expected_numerals, actual_numerals)

if __name__ == '__main__':
    unittest.main()

Note that the fixes above assume that the RomanNumeral class and its as_roman() and as_arabic() methods were implemented correctly and imported from a separate module called roman_numeral.py. Without the actual implementation, it is not possible to test the functionality or identify any bugs in the RomanNumeral class itself.
