A negated test is affirming a service is _not_ accessible.
Removing the test is not caring if the service is answering.
These are two different business needs.

Even if one confirms by some other means that a firewall product is 
running, there is only one way to confirm that product is doing its job. 
One must attempt to gain entry and see that access is denied.
