/*******************************************************************************
|

* This test verifies that various stack configurations result in the set of |
||||
* filters that we expect. |
||||
* |
||||
* This is akin to a golden-file test, and suffers the same disadvantages and |
||||
* advantages: it reflects that the code as written has not been modified - and |
||||
* valid code modifications WILL break this test and it will need updating. |
||||
* |
||||
* The intent therefore is to allow code reviewers to more easily catch changes |
||||
* that perturb the generated list of channel filters in different |
||||
* configurations and assess whether such a change is correct and desirable. |
