pytest: useful options

When invoking pytest, here are a couple useful configurations:

show logging output

$ pytest --capture=no --log-cli-level=DEBUG

spawn PDB with IPython upon exception

$ pytest --pdb --pdbcls=IPython.terminal.debugger:TerminalPdb

use breakpoint() (Python 3.7+)

if va == 0x401000:
    breakpoint()

use interact to drop into IPython shell from ipdb

ipdb> interact
*interactive*
