7 # pytest at certain points during operation, e.g. startup, for each executed
8 # test, at shutdown etc. These hooks perform functions such as:
9 # - Parsing custom command-line options.
10 # - Pullilng in user-specified board configuration.
11 # - Creating the U-Boot console test fixture.
12 # - Creating the HTML log file.
13 # - Monitoring each test's results.
14 # - Implementing custom pytest markers.
