Root Test Configuration — Global Guards Against Environmental Pollution
|
|
=======================================================================
|
|
|
|
This conftest protects ALL tests from the #1 cause of mass failure:
|
|
Config() constructor calling argparse.parse_known_args() which reads
|
|
sys.argv (pytest's arguments) and crashes with SystemExit: 2.
|
|
|
|
Every test directory inherits these fixtures automatically.

Root cause: Config.__init__ calls self.parse_args() which calls

pytest flags like '--ignore=...' which argparse interprets as

Fix: Temporarily set sys.argv to a minimal list so argparse

doesn't choke on pytest's arguments.
