In the cold light of morning, I see that in this invocation, the path
is wrong. But even if I correct it, I get the same results:
e:\Projects\mcm>py -m unittest ./test/db/test_manager.py

This is using the path correction I mention above. (But just to be
certain, I also did the exact path Peter gave with the same results.)

The reason that I have been trying to invoke this individual test
module the way I have is because in the docs it says:
26.3.2. Command-Line Interface
The unittest module can be used from the command line to run tests
from modules, classes or even individual test methods:
python -m unittest test_module1 test_module2
python -m unittest test_module.TestClass
python -m unittest test_module.TestClass.test_method
You can pass in a list with any combination of module names, and fully
qualified class or method names.
Test modules can be specified by file path as well:
python -m unittest tests/test_something.py
This allows you to use the shell filename completion to specify the
test module. The file specified must still be importable as a module.
The path is converted to a module name by removing the ‘.py’ and
converting path separators into ‘.’
So I am still quite confused!
Uh, oh, I have to leave for work. Peter, I have not made it to the
rest of your comments yet. That will have to wait till this evening,
but many thanks for the assistance! If the answer is in your
remaining comments, then I apologize for the additional noise in
advance!!
