import boto3
from moto import mock_s3


def create_s3_bucket(bucket_name: str, aws_region: str):
    s3_client = boto3.client("s3", region_name=aws_region)
    s3_client.create_bucket(
        Bucket=bucket_name, CreateBucketConfiguration={"LocationConstraint": aws_region}
    )


@mock_s3
def test_integration_with_s3():
    create_s3_bucket(bucket_name="foo", aws_region="eu-central-1")
