I managed to fix stack variables but now Im hitting another problem. I pulling up az list with function:

# Get az's for region
azs = aws.get_availability_zones(state="available")

Now when I try to run test :

File "/Users/unittests/infra.py", line 79, in <module>
    for num, az in enumerate(azs.zone_ids):
TypeError: 'NoneType' object is not iterable

in Pulumi documentation i found:

call(token: string, args: any, provider?: undefined | string): Record<string, any>
call mocks provider-implemented function calls (e.g. aws.get_availability_zones).

But I have no idea how I can mock this call. For any code snippet I would be grateful

You’ll want the mock to return the same ‘shape’ as what the function actually returns. The

token

refers to the function being called. For example, if you look at https://github.com/pulumi/pulumi-aws/blob/master/sdk/python/pulumi_aws/acm/get_certificate.py#L103
