The script run_test.pl is a test runner that work in conjunction with ps2autotests (https://github.com/unknownbrackets/ps2autotests)
Mandatory Option
--exe <STRING> : the PCSX2 binary that you want to test
--cfg <STRING> : a path to the a default ini configuration of PCSX2
--suite <STRING> : a path to ps2autotests test (root directory)
Optional Option
--cpu=1 : the number of parallel tests launched. Might create additional issue
--timeout=20 : a global timeout for hang tests
--show_diff : show debug information
--test=<REGEXP> : filter test based on their names
--regression : blacklist test that are known to be broken
--option <KEY>=<VAL> : overload PCSX2 configuration option
--debug_me : print script info
--dry_run : don't launch PCSX2
PCSX2 option
EnableEE=disabled : Use EE interpreter
EnableIOP=disabled : Use IOP interpreter
EnableVU0=disabled : Use VU0 interpreter
EnableVU1=disabled : Use VU1 interpreter
FPU.Roundmode=3 : EE FPU round mode
VU.Roundmode=3 : VU round mode
