07/27/2021, 5:42 PMNew to pulumi and trying my hand at unit testing in golang. My code uses config values that are set, but the test always panics saying the config value is not set. How can I tell the test that about the config values set for my stack?

hey @freezing-greece-4855 looks like this issue:
https://github.com/pulumi/pulumi/issues/4472
Props to @red-match-15116 for reminding me about this
Essentially, you'll need to set the config via environment variables unfortunately 😞
