Still can't figure out how to do unit testing with remote component resources. This will panic. I've tried different things to mock the underlying bucket, which didn't work.

package main

import (
	"testing"

	"<http://github.com/pulumi/pulumi-awsx/sdk/go/awsx/cloudtrail|github.com/pulumi/pulumi-awsx/sdk/go/awsx/cloudtrail>"
	"<http://github.com/pulumi/pulumi/sdk/v3/go/common/resource|github.com/pulumi/pulumi/sdk/v3/go/common/resource>"
	"<http://github.com/pulumi/pulumi/sdk/v3/go/pulumi|github.com/pulumi/pulumi/sdk/v3/go/pulumi>"
	"<http://github.com/stretchr/testify/assert|github.com/stretchr/testify/assert>"
)

type mocks int

// Create the mock.
func (mocks) NewResource(args pulumi.MockResourceArgs) (string, resource.PropertyMap, error) {
	outputs := args.Inputs.Mappable()
	if args.TypeToken == "awsx:cloudtrail:Trail" {
		//outputs["bucket"] = (&s3.Bucket{Bucket: pulumi.String("fake").ToStringOutput()}).ToBucketOutput()
		//outputs["bucket"] = &s3.Bucket{}
	}
	return args.Name + "_id", resource.NewPropertyMapFromMap(outputs), nil
}

func (mocks) Call(args pulumi.MockCallArgs) (resource.PropertyMap, error) {
	outputs := map[string]interface{}{}
	return resource.NewPropertyMapFromMap(outputs), nil
}

func TestCloudTrail(t *testing.T) {
	err := pulumi.RunErr(func(ctx *pulumi.Context) error {
		trail, err := cloudtrail.NewTrail(ctx, "test-trail-go", &cloudtrail.TrailArgs{
			IncludeGlobalServiceEvents: pulumi.Bool(false),
			EnableLogging:              pulumi.Bool(true),
		})
		assert.NoError(t, err)
		assert.NotNil(t, trail.Bucket.Bucket())

		return nil
	}, pulumi.WithMocks("project", "stack", mocks(0)))

	assert.NoError(t, err)
}

could you file a github issue for this?

Oh I thought I was doing something wrong.
