I have created a component resource that makes a call to
in order to grab the current account id of the locally assumed aws role so it can be used to define an arn in a policy doc: (code snippet has been truncated to save space)
Copy code
import pulumi_aws as aws

# gets account id
current = aws.get_caller_identity()
account_id = current.account_id

# passes account id when defining policy
self.lambda_policy = aws.iam.RolePolicy(
                lambda physical_name: json.dumps(
                        "Version": "2012-10-17",
                        "Statement": [
                                "Effect": "Allow",
                                "Action": "logs:CreateLogGroup",
                                "Resource": f"arn:aws:logs:us-east-1:{account_id}:*"

When I instantiate this component resource in my project
, it works as expected. However, when I run
, I get the following error:
Copy code
________________________________ ERROR collecting tests/test_ip_scan.py _________________________________

    test_args = ip_scan.MonitorAvailableIpsArgs(

Any and all feedback is greatly appreciated!
Ok I figured this one out. I had to mock the function call as follows:
Copy code
class MyMocks(pulumi.runtime.Mocks):
    def new_resource(self, args: pulumi.runtime.MockResourceArgs):
        return [args.name + "_id", args.inputs]

    def call(self, args: pulumi.runtime.MockCallArgs):
        if args.token == "aws:index/getCallerIdentity:getCallerIdentity":
            return {
                "accountId": "123456789",
                "arn": "myarn",
                "id": "myid",
                "userId": "achang3"
        return {}
