Wexpect logging
Wexpect has a debug logging feature, which is disabled by default. The logs contain useful information about starting and communicating with the console-reader process, which is useful for debugging an issue. Wexpect uses python's built-in logging feature.
To turn on the logging, set the WEXPECT_LOGGER_LEVEL environment variable to one of the following: SPAM, DEBUG, INFO, WARNING, ERROR. I use DEBUG for testing the start of the wexpect and INFO for longer tests. To set the DEBUG level use the following command:
set WEXPECT_LOGGER_LEVEL=DEBUG
Wexpect will generate two logfiles: one for the host process, and another for the console-reader process. The log files will be generated into .wlog subdirectory by default, and will be named based on the process PID.
To give a custom name, use the WEXPECT_LOGGER_FILENAME environment variable. (not recommended.)
