## Code Before:
from nose.tools import assert_equals

from botocore import exceptions


def test_client_error_can_handle_missing_code_or_message():
    response = {'Error': {}}
    expect = 'An error occurred (Unknown) when calling the blackhole operation: Unknown'

    response = {'Error': {}}
    exception = exceptions.ClientError(response, 'blackhole')
    assert_equals(exception.operation_name, 'blackhole')

Add test to check excplicitly if the attribute is set
