Locust.io come posso usare diversi utenti su locust.io senza che il sistema si interrompa quando avvio/arresto per una nuova corsa

Question

Ho questo codice che funziona bene per la prima esecuzione su un server distribuito locust.io, ma quando avvio/arresto per eseguire una nuova esecuzione ottengo più errori, rispetto all'elenco. Potresti aiutarmi a pedalare?

from locust import HttpUser, task, between, SequentialTaskSet, events
import uuid
import json
import csv
import logging, sys, random, os

with open('somecsv.csv', 'r') as f:
    reader = csv.reader(f)
    user= list(reader)
    #print(user)

class somethingclass(SequentialTaskSet):

    def on_start(self):
        if len(user) > 0:
            self.id= str(user.pop()).strip("][''")

    @task
    def someting(self):
        do something with self.id request
  
    @task
    def someting2(self):
        do something with self.id request
                        


class Main(HttpUser):
    
    wait_time = between(5, 10)
    tasks = [somethingclass]
    
    def _init_(self, *args, **kwargs):
        super(Main, self)._init_(*args, **kwargs)

gli errori sono:

[2020-08-18 23:06:50,899] PC/ERROR/locust.user.task: l'oggetto 'qualcosaclasse' non ha l'attributo 'id' Traceback (ultima chiamata più recente): File "c:\windows\system32\src \locust\locust\user\task.py", riga 284, in run self.execute_next_task() File "c:\windows\system32\src\locust\locust\user\task.py", riga 309, in execute_next_task self .execute_task(self._task_queue.pop(0)) File "c:\windows\system32\src\locust\locust\user\task.py", riga 321, in execute_task task(self) File "C:\Users\ user\Desktop\Work\Chipico Chip Transfer\chiptransfer_load.py", riga 44, in qualcosa "uuid": '%s' % self.id, AttributeError: l'oggetto 'somethingclass' non ha l'attributo 'id'

Puoi utilizzare gli eventi test_start e test_stop per reimpostare i tuoi userdati.

from locust import User, task, constant, TaskSet, events
from logging import getLogger
import uuid

logger = getLogger("test")
user = []

@events.test_start.add_listener
def start_something(**kwargs):
    logger.info("Starting test...")
    user.append(uuid.uuid4())

class somethingclass(TaskSet):
    @task
    def do_something(self):
        logger.info(f"User: {user}")

class Main(User):
    wait_time = constant(2)
    tasks = [somethingclass]

Questo mi dà il seguente output con più arresti e avvii di test.

Answer 2

from locust import Utente, attività, costante, TaskSet, eventi da logging import getLogger import uuid

logger = getLogger("test") utente = []

@events.test_start.add_listener def start_something(**kwargs): logger.info("Avvio test...") user.append(uuid.uuid4())

class qualcosaclass(TaskSet): @task def do_something(self): logger.info(f"Utente: {utente}")

class Main(Utente): wait_time = constant(2) task = [somethingclass]

è la risposta corretta
