Do you have the pulumi cli installed?
p
yes
s
How are you invoking the tests? It has to be through the pulumi cli, not with node
p
thats not what the docs say?
Copy code
"test": "mocha -r ts-node/register '**/*.test.ts'",
l
In general, you cannot call any Pulumi functions in unit code unless you wrap your test in 
pulumi.runInPulumiStack()
. You shouldn't often need to using Pulumi functions in testable units, so it's not much of an issue.
A ComponentResource shouldn't access Pulumi config, call 
getStack()
or 
getProject()
, or anything like that. All that stuff should happen in your program and be passed into your ComponentResources. That way, they're testable.
p
interesting, let me give that a go
These are just helpers to build extended component resource options, we don’t usually build providers in code we wish to unit test.
