Is there a question here?

Since you post quite a lot it would be really nice, at least for me, if you learnt to mark your code as code here.

Killing a Python PyQt GUI process should be no different than killing any other process.

Hi,

Beside @JonB's good point, why not just use QApplication.quit ?
What is your exact use case ?

I have to write a behave test case

where I have test invoking of the pyqt based gui and stop the gui .

@given(u'an GUI invoke command')
def step_impl(context):
print("\n 1111")
file1 = open("myfile.txt","a")
file1.write("\n1111")
sys.stdout.flush()
context.command = "guiexec &"
file1.write("\n2222")
file1.close()
print("\n 3333")
sys.stdout.flush()

@when(u'the GUI invoke command is run')
def step_impl(context):
context.co = start_process_and_kill()
context.result = context.co.sp_call(context.command)

class start_process_and_kill():
# behave testcase code to check process gui invoke on windows/linux platform
def init(self):
self.cmd = None
self.process_output = None

def start_proces(self,cmd):
     subprocess.Popen(cmd) 	

def kill_process_in_linux(self):
    cmd = "pkill -f " + self.cmd
    time.sleep(5)
    os.system(cmd)

def kill_process_in_windows(self):
    
    time.sleep(5)
    file1=  open("myfile.txt","a")
    file1.write("\nwindows start")
    file1.close()
    
    print("\n IN kill_process_in_windows") 		
    processes = [process.info for process in psutil.process_iter(attrs=['pid', 'name']) if 'python' in process.info['name']]
    max_time = "00:00:00"
    process_pid = None
    process_info_dict = {}
    for process_info in processes:
	
        process_detail_info = psutil.Process(process_info["pid"])
        process_creation_time = datetime.datetime.fromtimestamp(process_detail_info.create_time()).strftime("%H:%M:%S")
        process_info_dict[process_creation_time] = process_info
        print(process_info_dict)
	
    #max_time = max(process_info_dict.keys())
    required_pid = process_info_dict[max_time]["pid"]
    strin1 = "taskkill /F /PID {}".format(required_pid)
    #os.system('taskkill /F /PID' + required_pid)
	
    keylist = process_info_dict.keys()
    file1=  open("myfile.txt","a")
    file1.write("\nwindows kill111")
    file1.close()
    keylist.sort() 
    key2 = keylist[-2]
    pid = process_info_dict[key2]['pid']
    pidStr = repr(pid)
    str = 'taskkill /F /PID ' + pidStr
    print(str)
    os.system(str)				
    print("11")

def call_process(self):
self.process_output = subprocess.check_output(self.cmd, shell=True, stderr=subprocess.STDOUT)

def sp_call(self,cmdline,shell=False,module=False):
    self.cmd = cmdline
    process_kill = None
    if platform.system().find("Linux") >= 0:
        process_kill = threading.Thread(target=self.kill_process_in_linux)
    elif platform.system().find("Windows") >= 0:
        print("1112")      
        process_kill = threading.Thread(target=self.kill_process_in_windows)
        file1 = open("myfile.txt","a")
        file1.write("\nwindows kill")
        file1.close() 			

		#subprocess.Popen(self.kill_process_in_windows)
    process_start = threading.Thread(target=self.call_process)

    process_kill.start()
    process_start.start()

    process_kill.join()
    process_start.join()
	
    file1 = open("myfile.txt","a")
    file1.write("\nwindows kill done")
    file1.close() 			

    return self.process_output

Please suggest better way that I test invoking and quit of GUI in behave test case

Hi,

Use something designed for Qt testing like pytest-qt.
