Likely copy-paste from the earlier iteration of this pull request, the test configuration resource name is aws_cloudwatch_dashboard.test:

https://github.com/terraform-providers/terraform-provider-aws/blob/e1fc857056e66b257520f73ca5e22dc6facaebef/aws/resource_aws_cloudwatch_dashboard_test.go#L159

Otherwise, this test causes this error:

--- FAIL: TestAccAWSCloudWatchDashboard_updateName (5.64s)
    testing.go:640: Step 0 error: Check failed: Check 1/3 error: Not found: aws_cloudwatch_dashboard.foobar

Since it is a small testing fix, will do so on merge. 👍

Gah, I was so close. Thanks!
