我正在尝试使用boto3和aws运行集成测试。似乎测试无法连接到localhost端点，因此测试失败。我很确定我已经正确配置了aws环境变量。我怀疑也许没有本地服务器在运行，但是我仍然不确定如何解决该问题。任何帮助将不胜感激。
我在Mac Mojave上运行，我尝试过更改服务器试图连接到localhost：3000的端口。我还尝试使用AWS Step Functions（https://docs.aws.amazon.com/step-functions/latest/dg/sfn-local-config-options.html）连接到正在运行的服务器，但是没有运气。
来自日志的错误消息：
ConnectionRefusedError: [Errno 61] Connection refused
和
raise EndpointConnectionError(endpoint_url=request.url, error=e)
botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: "http://127.0.0.1:3001/2015-03-31/functions/AthenaDatabaseProvider/invocations"

答案 0 :(得分：0)
结果是，运行测试时，我需要运行docker应用。希望这可以帮助可能遇到相同问题的人！
