I am looking to add test coverage to my custom provider created using the pulumi-provider-go, are there any examples of using the integration server to test component creation? I only see an example of testing function invocations <https://github.com/pulumi/pulumi-go-provider/blob/main/examples/str/main_test.go|here> but not seeing how I would test a resource/component. Thanks.

To test a resource, I would use a <https://github.com/pulumi/pulumi-go-provider/blob/e8f254577aee9fba48c3a8cf7238ef95a4b14141/integration/integration.go#L161-L166|life cycle test> (<https://github.com/pulumi/pulumi-go-provider/blob/e8f254577aee9fba48c3a8cf7238ef95a4b14141/examples/random-login/main_test.go#L146-L175|example>).

Components only have the `Construct` function, so you can test them by calling `server.Construct` (<https://github.com/pulumi/pulumi-go-provider/blob/e8f254577aee9fba48c3a8cf7238ef95a4b14141/integration/integration.go#L44|here>) instead of calling `server.Invoke`.

I am struggling figuring out how to return a ConstructResponse from that

I’m not sure I understand. Do you have a branch/gist/code that I could look at?

```server := integration.NewServer("foo", semver.Version{Minor: 1}, provider())
	r, err := server.Construct(p.ConstructRequest{
		URN:     "urn:pulumi:dev::test::foo:bar:Bar::test",
		Preview: false,
		Construct: func(ctx p.Context, cf p.ConstructFunc) (p.ConstructResponse, error) {
			comp, err := cf(ctx, ComponentArgs{
				Fizz: "Buzz",
			})
			if err != nil {
				return nil, err
			}
			return ????, nil
		},
	})```

^ that Construct function has a return of ConstructResponse and it isn’t clear how to get that from what I have

Perhaps you could provide an example using the RandomLogin <https://github.com/pulumi/pulumi-go-provider/blob/e8f254577aee9fba48c3a8cf7238ef95a4b14141/examples/random-login/main.go|here>

I see the problem here. Its not possible to use `integration` with a component resources right now.

As a workaround, you could return a zero value of `p.ConstructResponse{}` and assert within the `p.ConstructRequest.Construct` function that `comp` has the desired output.

I opened <https://github.com/pulumi/pulumi-go-provider/issues/82> to track this problem.
