HALP! Mah unit tests be doin' too much I/O! Testin' this lil' codes uses MOAR RESOURCES!
GIMME lol_io LIKE LOLIO
SO IM LIKE PROCESSIN WIT DATAZ OK?
GIMME EACH BUCKET IN UR DATAZ OK?
BUCKET OWN FUBARRED?
N CAN HAS NONE
N CAN HAS 1
IZ __name__ KINDA LIKE “__main__”?
UR PROCESSIN WIT LOLIO OWN GET_SOME_DATAZ
BTW, GET_SOME_DATAZ USES UR INTERNETS LOL
Oh NOES! Usin' internets in ur unit testz? Don't clog the tubes! Is not big truck! Mock the LOLIO thingy. No moar tubes!
GIMME mock_lol_io LIKE LOLIO
BTW, GIMME THING TO TEST
BTW, TEST THE THING NOW KTHX
Now ur test runs fast! You can use mock_lol_io for killin' nondeterminism, too like for exceptions n stuff. Is fun, makes ur code execute pathz it nevar seen b4. Wit dis, you can see wut happens when theres a OH NOES like the tubez bein clogged.
BTW, SOMETIMES THEY BE CALLIN DIS DEPENDENCY INJECTION ROFL
BTW, YOU CAN UZE MOCKZ N STUF FER DIS LOOK:
IN MAI library GIMME mock_filesystem LIKE LOL_FAKE_FILEYSTEM
BTW, NOW U CAN USE LOL_FAKE_FILESYSTEM TO MAKE FAKE FILEZ IN MEMORY N STUFF
BTW, IS FASTER THAN OPENIN FILEZ ON TEST SERVAR
Now U know the sekrit for faster tests. Shh, don't tell Microsawft or the Yahew. They might be in our base, stealin our tech!
