Way to use locust.io by supplying user list

Question

I need to stress-test a system and http://locust.io seems like the best way to go about this. However, it looks like it is set up to use the same user every time. I need eac

Alternatively, you can create users.py module to hold the users' information you need in your test cases, in my example, it holds email and cookies. Then you can call them randomly in your tasks. See below:

# locustfile.py
from locust import HttpLocust, TaskSet, task
from user_agent import *
from users import users_info


class UserBehaviour(TaskSet):
    def get_user(self):
        user = random.choice(users_info)
        return user

    @task(10)
    def get_siparislerim(self):
        user = self.get_user()
        user_agent = self.get_user_agent()
        r = self.client.get("/orders", headers = {"Cookie": user[1], 'User-Agent': user_agent})

class User(HttpLocust):
    task_set = UserBehaviour
    min_wait = 5000
    max_wait = 60000

User and user-agent can be called by a function. With this way, we could distribute the test with many users and different user-agents.

# users.py

users_info = [
['performancetest.1441926507@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926506@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926501@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926499@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926494@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926493@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926492@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926491@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926490@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926489@gmail.com', 'cookies_created_by_each_user'], 
['performancetest.1441926487@gmail.com', 'cookies_created_by_each_user']]
