# Implementation of pytest run-time hook functions. These are invoked by
# pytest at certain points during operation, e.g. startup, for each executed
# test, at shutdown etc. These hooks perform functions such as:
# - Parsing custom command-line options.
# - Pullilng in user-specified board configuration.
# - Creating the ubman test fixture.
# - Creating the HTML log file.
# - Monitoring each test's results.
# - Implementing custom pytest markers.
