i have java test framework set using testng , maven. tests organized suites via testng xml files. i share state between different test classes in same suite. specifically, want share id 'test plan' created in testrail test case manager @ start of test suite execution. how that? testng doesn't seem offer functionality transferring information between test classes, , i'm unsure of how @ maven level either. static variable in parent class work, or leak or cause many thread-safety issues? update: have decided solve problem using static variable in parent class (which holds various state tests running). use case, i'm not run multiple instances of parent class concurrently in same jvm in way needs static variable threadsafe. however, still open other ideas on how accomplish this, because enjoy learning new things. i think can use beforemethod annotation , put stuff desired state before each test execution. more "state sharing" not desired....

i trying calls wcf services use load balancer (an f5). the problem when try set 1 of machines in pool "disabled" still send requests through machine. the documentation f5 says when server disabled "only persistent or active connections allowed". i wondering if wcf using persistent connection (or similar) bypassing loadbalancer's efforts disable node on server. (the goal disable server, active connections out, update code on server, re-enable it.) does wcf use persistant connections default? if so, way turn off? there no default connections in wcf (you mean - communication channels) depends explicit or implicit (via factories) hosting configurations. the (true-)'persistent' communication provided duplex nettcpbinding (active connections). durable services allows other (business-)dimension of persistence (via http, connections not open, active). wcf sessions, reliable sessions - same story - fake 'persistence'. so che...

i saw post on reddit counterexample euler's conjecture. decided try brute force calculation myself. my code import numpy np fifths1 = np.arange(1,151) fifths = fifths1**5 x in fifths1: y in fifths1: z in fifths1: w in fifths1: lambdas=[x,y,z,w] if sum(np.array(lambdas)**5) in fifths: print((x,y,z,w)) however, code takes long because triple checks cases. from paper linked, counter example is 27^5 + 84^5 + 110^5 + 113^5 = 144^5 my code returns (27, 84, 110, 133) (27, 84, 133, 110) (27, 110, 84, 133) (27, 110, 133, 84) (27, 133, 84, 110) (27, 133, 110, 84) how can optimize brute force search not check same case multiple times. i think numpy wrong library use here. this isn't problem can vectorised in current form (the biggest reason use library) and, furthermore, looping on numpy arrays slower looping on python lists. you incur performance penalty constructing new...

i want make simple python 3 script generate single keypress (f15). don't want use bunch of libraries need 1 key pressed , don't need support whole keyboard. know need use keypress , keyrelease in order generate keyboard event. i'm not sure start , documentation little confusing. http://tronche.com/gui/x/xlib/events/keyboard-pointer/keyboard-pointer.html http://python-xlib.sourceforge.net/?page=documentation i'll use ctypes show how work, porting python-xlib should straightforward. lets start loading library: import ctypes x11 = ctypes.cdll("libx11.so") and defining structures needed: class display(ctypes.structure): """ opaque struct """ class xkeyevent(ctypes.structure): _fields_ = [ ('type', ctypes.c_int), ('serial', ctypes.c_ulong), ('send_event', ctypes.c_int), ('display', ctypes.pointer(display)), (...
