Hey, question about how to check values in testing. I have the following in my `index.ts`:

export const service = new awsx.ecs.FargateService("click-router", {
  assignPublicIp: false,
  cluster,
  subnets: pubSubnets,
  desiredCount: 2,
  taskDefinition: taskDef
});

and then in my tests, I’m trying to do:

it("should have 2 desired instances", async () => {
    const di = await promise(service.service.desiredCount);
    expect(di).to.equal(2);
  });

I get the error that the variable

di

is undefined. How can I do tests on assigned values prior to deploying?

do you get this error when doing an

up

or

preview

or are you executing pulumi in a different way?

This is with an `up`…should I be using

preview

?

No, the tests will execute in both. Let me try to reproduce...

thanks, let me know

@witty-yacht-82771 looks like this currently doesn't work in

preview

(https://github.com/pulumi/pulumi/issues/3429), but should work during the

up

. If you're running

pulumi up

, pulumi will run the preview first and if anything fails will not proceed to the update. You can skips the tests during the

up

by checking

pulumi.runtime.isDryRun()

.

Cool, good to know, I’ll add that to my internal docs for now
