Testing - Not detecting that is running a test

Untitled.ts

Here’s my code, I’m using `jest` but same happens with `mocha` so it’s not the testing framework.

Somehow `pulumi` is requiring my configuration values..

I’m using the `config.require('somevalue')` in some places of my code. to inject configuration from the `.yaml` files, however I don’t want this behavior in unit testing. But even initializing the `setMocks` function with the `project` and `stack` arguments, it doesn’t get the values from the `yaml` files. :confused:

Hopefully none of my colleagues are going to correct me, but it's still running your pulumi program, just without hitting the provider's api. So if you've got config somewhere in there, it means you'll need to have that config value in your stack config

But I have the config in there, maybe because it’s running from a test is not detecting it?

<https://github.com/pulumi/pulumi/issues/4472>

So the only solution is either providing environment variables with the `config` values to the test, or read the `yaml` config into `json` and export it as a variable? :confused:

Correct, if you want to test with a specific config, then those are currently the primary options. One thing I would ask is what are you testing w.r.t. reading from config since config is generally stack-specific and I would typically expect the unit test to be testing the program itself and not relying on any specific config values?

Yeah I think i’m just going to mock the required configuration and that’s it :slightly_smiling_face:

I would like to just take from `index.ts` a single constant, like my `resourceGroup` for azure, but this code actually makes it so I cannot do it:

``` let infra: typeof import('../index');

  beforeAll(async function () {
    infra = await import('../index');
  });```
If I try to adapt it slightly to just take the exported constant it doesn’t work. :confused:

Also when I’m trying to import `nested` config objects I get this error:
```Configuration 'project:services' value '[object Object]' is not a valid JSON object```
Example of this `services` object:
``` project:services:
   myapp1Version: 23
   myapp2Version: 24```
JSON string:
```{"project:baseDomain":"mydomain.dev","project:services":{"myapp1Version":23,"myapp2Version":24}}```
Isn’t there a better way to inject configuration? Some `pulumi.runtime` method or something?
