How to rm state not destroy resource in acceptance testing

My code is as below, how can I only rm state instead of destroy resource, so I can import this resource again.

func TestAccProject_importBasic(t *testing.T) {
	resourceName := "lxd_project.project0"

	resource.Test(t, resource.TestCase{
		PreCheck:                 func() { acctest.PreCheck(t) },
		ProtoV6ProviderFactories: acctest.ProtoV6ProviderFactories,
		Steps: []resource.TestStep{
				Config: testAccProject_basic("project0"),
				ResourceName:                         resourceName,
				ImportStateId:                        "project0",
				ImportState:                          true,
				ImportStateVerify:                    true,
				ImportStateVerifyIdentifierAttribute: "name",

Hi @shufanhao :wave: Thank you for raising this topic.

While the acceptance testing library could introduce a specific enhancement for this type of behavior (e.g. Acceptance testing: Ability to prevent a resource being deleted at the end of a `TestCase` · Issue #85 · hashicorp/terraform-plugin-testing · GitHub), any testing can immediately utilize any available Terraform configuration capabilities. In this case, Terraform 1.7 and later support the removed configuration block for this purpose, rather than the previously required running of the terraform state rm command.

In your case, you should be able to add a final TestStep with a Config that does not include the resource block of the resource you wish to preserve, but does include the removed block with destroy = false for that resource instead.

Please give that a try and let us know if that does not work as expected.
