I am trying to run integration tests using boto3 and aws. It seems the tests are unable to connect to the localhost endpoint so the tests are failing. I'm quite sure I've configured my aws environment variables correctly. I suspect that maybe there is no local server running but I'm still unsure how to fix the problem. Any help would be greatly appreciated.
I'm running on Mac Mojave, I've tried changing the ports that the server is attempting to connect to localhost:3000. I've also tried connecting to a server that I'm running using AWS Step Functions (https://docs.aws.amazon.com/step-functions/latest/dg/sfn-local-config-options.html) but with no luck.
Error messages from Log:
ConnectionRefusedError: [Errno 61] Connection refused
and
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"

I don't know how to solve this issue. Maybe it's because I worked behind a proxy? If so, how to make urllib.urlretrieve work behind the proxy?
Add proxy settings to your global environment to see if it fixes the problem.
sudo gedit /etc/environment
Then add these two lines
http_proxy=http://your_proxy.com:443
https_proxy=https://your_proxy.com:443
