Using LogEnabler in wxFileSystemWatcher test case still didn't show
anything even in case of unexpected failures because debug messages
didn't appear in the test output.
Fix this by using a custom log target which shows the debug (and trace)
messages on stderr, instead of using the debug output for them, even
under MSW.
Also make LogEnabler public, and rename it to a more unique name, as it
could be useful in the other tests too.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
