Writing Provider Tests

func TestAccAWSInstance_basic(t *testing.T) {
    resource.ParallelTest(t, resource.TestCase{
        PreCheck:     func() { testAccPreCheck(t) },
        Providers:    testAccProviders,
        CheckDestroy: testAccCheckAWSInstanceDestroy,
        Steps: []resource.TestStep{
            {
                Config: testAccAWSInstanceConfig_basic,
                Check: resource.ComposeTestCheckFunc(
                    testAccCheckAWSInstanceExists("aws_instance.test"),
                    resource.TestCheckResourceAttr("aws_instance.test", "instance_type", "t3.micro"),
                ),
