Hi y'all! How do I set up a fake GCP provider for unit testing? I am already setting up mocks as in the documentation, however I need to

gcp.config.region

to have a value during testing. Any idea?

We don't currently support mocking of the config object, but there's a workaround posted at https://github.com/pulumi/pulumi/issues/4472#issuecomment-618053293. You can subscribe to that issue to get updates on it.

thanks. Is there a transformation of gcp:region into gcp.config.region ? Is there a method on the config to list all the parameters?

Thank you @gentle-diamond-70147 what I did in the end was to make Pulumi read one of my stack configuration files:

stack = os.environ['PULUMI_STACK']
pulumi.runtime.set_mocks(PulumiMocks())
pulumi.runtime.settings._set_project(project_name)
pulumi.runtime.settings._set_stack(stack)

config_file = f'Pulumi.{stack}.yaml'
assert os.path.exists(config_file), f'Pulumi stack configuration file {config_file} should exist'

with open(config_file) as f:
    config = yaml.load(f)['config']

for key, value in config.items():
    config_value = value if not isinstance(value, (dict, list)) else json.dumps(value)
    pulumi.runtime.set_config(key, config_value)

😄

@steep-alligator-79173 this is what I do in my conftest.py (I am using pytest) ☝️

im new with testing so Im trying to follow unittest examples from pulumi website

I tried what you are doing, results that your config_instance variable will be empty. you need, in your test, to fill the config somehow. The way I found is with

pulumi.runtime.set_config(key, config_value)

ok thx for the tip

I have been using pytest for a long time. I like it more, because

fixtures

I managed to fix config variable problem with @flat-australia-79845 tip but now I’m getting

I think that's unrelated? was your infra setup working?

this is a simple ec2 instane

import pulumi
import pulumi_aws as aws
from pulumi import get_stack, ResourceOptions, StackReference
from pulumi_aws import ec2, lb

# Get AZS
azs = aws.get_availability_zones(state="available")

# Get network stack outputs
network_stack = StackReference("dev-network")

# Get VPC id
vpc = network_stack.get_output("vpc_id")

# Get public subnets ids
subnet_public_ids = network_stack.get_output("subnet_public_ids")

# Get private subnets ids
subnet_private_ids = network_stack.get_output("subnet_private_ids")

# Get instance stack config
config_instance = pulumi.Config("instance")
config_instance = pulumi.Config("instance")

# SSH access security group
sg_ssh = aws.ec2.SecurityGroup(
  f"qx-poc-{pulumi.get_stack()}-ssh",

  ],
  tags={

  ],
  egress=[
    { 'protocol': 'tcp', 'from_port': 80, 'to_port': 80, 'cidr_blocks': ['0.0.0.0/0'] },
  ]
)

bastion = ec2.Instance(
  f"bastion-qx-poc-{pulumi.get_stack()}",
  instance_type=config_instance.require('bastion_size'),
  vpc_security_group_ids=[sg_ssh.id],
  ami=config_instance.require('bastion_ami'),

  }
)

the error message you sent me before is all you get?
