Basic Walk Test
When the tester activates an input during Basic Walk Test, all silenceable outputs mapped by CBE to that input will activate. The activations are track-

Advanced Walk Test
During Advanced Walk Test, when the tester activates an input, all CBE mapped to that input will activate with the exception of releasing functions.
