+The debugging of the test programs is best performed running the low-level test-runner program. The test-runner is the bridge from generic Python code to |ns3| code. It is written in C++ and uses the automatic test discovery process in the 
 |ns3| code to find and allow execution of all of the various tests.
 
-Although it may not be used directly very often, it is good to understand how
-``test.py`` actually runs the various tests.
+The main reason why ``test.py`` is not suitable for debugging is that it is not allowed for logging to be turned on using the ``NS_LOG`` environmental variable when test.py runs.  This limitation does not apply to the test-runner executable. Hence, if you want to see logging output from your tests, you have to run them using the test-runner directly.
 
 In order to execute the test-runner, you run it like any other ns-3 executable
