我正在尝试使用 boto3 和 aws 运行集成测试。测试似乎无法连接到本地主机终结点，因此测试失败。我很确定我已经正确配置了我的 aws 环境变量。我怀疑可能没有本地服务器正在运行，但我仍然不确定如何解决问题。任何帮助将不胜感激。
我在 Mac Mojave 上运行，我尝试更改服务器尝试连接到 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，但没有运气。
日志中的错误消息：
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"

事实证明，当我运行测试时，我需要运行 docker 应用程序。希望这可以帮助可能遇到同样问题的人！
