Its all from Physical to other testings you do before you put them to Live network. Note the results for reference. I also call this as  SAT, Service acceptance Test.

1. Physical - Off the device and on the device it works ? yes or no ?

2. Remove the WAN Link and test is this working or not working,

3. Do some external Flooding / Stress testing against device see if the device perform as expected.

Note : do it in maintance window, some test may bring down the network.

I believe, in the general/generic sense, "intrusive testing" just means ANY testing that can be disruptive to other "normal" processing; to what degree might be described with other adjectives, like "minor" vs. "major".  An example of the former might be a few packets may be dropped, while the latter might be something like the link will drop for half a minute.

Unsure what you mean by looking for a "solution" to intrusive testing.

If it's legitimate testing, business policies normally address such, sometimes with "penalties" attached.  E.g. Doing intrusive testing during business hours may lead to employee termination.

If you mean non-legitimate testing, then you try to defend against it like you might against other DoS attacks.

I am not clear what the original poster means when he says "I am looking for solution to intrusive testing on Cisco Devices". Is a solution the same thing as an explanation of what it is? Or is a solutions suggestions about how to do it? 

I believe that @Joseph W. Doherty makes a good point that intrusive testing is testing that disrupts normal traffic flows. I think that the reference to T1 testing supports this interpretation. There are some types of problems where testing for that problem will be intrusive. As Joseph points out for these types of things you usually need to plan ahead, schedule a maintenance window, etc.
