Hi there, I got a question regarding unit testing: My tests are running in a time-out presumably because the infrastructure definition contains a getter. How to mock a getter on an existing resource? Let's say this is the index.ts with a

get

to import the default security group for further reference:

import * as aws from '@pulumi/aws';
import * as awsx from '@pulumi/awsx';

export const vpc = new awsx.ec2.Vpc('mdm-db-vpc', {
  subnets: [{ type: 'isolated' }],
});

export const securityGroup = aws.ec2.SecurityGroup.get(
  'default',
  vpc.vpc.defaultSecurityGroupId,
);

The

setMock

function takes an object that must have a

call

function. This function is where you fake out calls to Pulumi functions.

Thanks for the hints but it doesn't seem that the getter can be mocked within the

call

function of the mocks. I logged

args.token

of all invokations to the console and none of them where matching but I still had this error message.

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "Error: failed to read resource #undefined 'default' [aws:ec2/securityGroup:SecurityGroup]: req.getCustom is not a function".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Anyway I considered that I do not need to export the whole

securityGroup

just the

securityGroupId

that I already got from the VPC so problem solved. 🙂
