Cognito class instances talk to AWS at import time

[jordan-dimov]

Because of code like jwks = JWKS.fromurl(url) in the __init__(), it is impossible to import modules without them trying to connect to AWS Cognito at import time. This can cause a variety of problems, e.g. - unable to run unit tests without an Internet connection.

Hi @jordan-dimov I was following this issue as I am dealing with edge devices and this is definitely an issue at the moment.
Did you close because you found a workaround?
If so, could you share?

@Minipada Oh, good to know it's not just me. I thought maybe I wasn't using it correctly. Ended up creating a fake Cognito class just for my unit tests, and switching between those with an environment variable. Happy to re-open this though.

I've faced with the same issue trying to write unittests using moto to fake Cognito resources. And in my case there is no straightforward way to pre-configure environment variable, since I create AWS Cognito resources using fixtures (pytest). Any good ideas how to overcome this?

I have faced the same issue and found a good solution mentioned on another issue here: #32
