import boto3
import pytest
@pytest.mark.usefixtures("serverless")
def test():
table = boto3.resource("dynamodb").Table("my-microservice.my-table")
count_of_items = len(table.scan()["Items"])
assert count_of_items == 0You can use a custom serverless file path setting the envionmnet variable SERVERLESS_FILE_PATH.
$ export SERVERLESS_FILE_PATH=/path/to/serverless.ymlYou can use choose both sls or serverless command to run, settings the environment variable SERVERLESS_COMMAND. It will only accpets sls or serverless values.
$ export SERVERLESS_COMMAND=sls
