Hi! I am trying to write a simple unit test for my ts project. And I am stuck with configuration parsing. Maybe some of you already faced such problem and can help. me somehow? Here is my test:

import { NodeApplication } from "../src/nodeApplication";
import * as pulumi from "@pulumi/pulumi";

describe("Node Application", () => {
  test("Read from config", () => {
    const config = JSON.stringify({
      config: {
        'test:image': 'test',
        'test:team': 'test',
        'test:app': {
          redis: {
            url: '<redis://some-host:6379>',
          },
        },
      },
    });
    process.env.PULUMI_NODEJS_STACK = "unit";
    process.env.PULUMI_NODEJS_PROJECT = "test"
    process.env.PULUMI_CONFIG = config;
    console.log(process.env.PULUMI_CONFIG);
    console.log(pulumi.getProject()); // returns 'project' instead of 'test'
    console.log(pulumi.getStack()); // returns 'stack' instead of 'unit'
    const appConfig = new pulumi.Config();
    console.log(appConfig);
    console.log(process.env.PULUMI_CONFIG);
    let app = new NodeApplication(); // fails to find required configuration values
  });
});

Inside

NodeApplication

class there is a config parsing:

. . .
let config = new pulumi.Config();
this.name = pulumi.getProject();
this.image = config.require('image');
this.team = config.require('team');
. . .

I am running tests with jest. And here is an output (simplified):

$ npm run test

> test
> jest

  console.log
    {"config":{"test:image":"test","test:team":"test","test:app":{"redis":{"url":"<redis://some-host:6379>"}}}}

  console.log
    project

  console.log
    stack

  console.log
    Config { name: 'project' }

Wouldn't unit tests for Pulumi config be the responsibility of Pulumi? You shouldn't need to write unit tests that use Pulumi config.

Yeah. This code can also take values as an arguments. Without depending on Pulumi config. I thought, it would be useful to test cases when I’m using some values from Pulumi Comfig instead of arguments
