Error to login to webapp in Locust

[casidos]

I want locust to be able to login to my web application and start to click in the links inside the web application.

With this code I just get activity for the front page with the login and i don't get any notification from inside the application.

Code:

import random
from locust import HttpLocust, TaskSet, task
from pyquery import PyQuery

class WalkPages(TaskSet):
    def on_start(self):
        self.client.post("/", {
            "UserName": "[email protected]",
            "Password": "2Password!",
            "submit": "Sign In"
        })
       self.index_page()

@task(10)
def index_page(self):
    r = self.client.get("/Dashboard.mvc")
    pq = PyQuery(r.content)
    link_elements = pq("a")
    self.urls_on_current_page = []
    for l in link_elements:
      if "href" in l.attrib:
        self.urls_on_current_page.append(l.attrib["href"])

@task(30)
def load_page(self):
    url = random.choice(self.urls_on_current_page)
    r = self.client.get(url)


class AwesomeUser(HttpLocust):
    task_set = WalkPages
    host = "https://myenv.beta.webapp.com"
    min_wait = 20  * 1000
    max_wait = 60  * 1000

I get the follow msg in the terminal after the first round.

I am also facing same error,

[2015-07-31 15:51:23,258] JADEHOL1366/ERROR/stderr: Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/locust/core.py", line 264, in run self.schedule_task(self.get_next_task()) File "/usr/local/lib/python2.7/dist-packages/locust/core.py", line 325, in get_next_task return random.choice(self.tasks) File "/usr/lib/python2.7/random.py", line 273, in choice return seq[int(self.random() * len(seq))] # raises IndexError if seq is empty IndexError: list index out of range

@casidos this part of the error list clearly says what's wrong:

File "/home/webapp/LoadTest/locustfile.py", line 31, in load_page
url = random.choice(self.urls_on_current_page)
File "/usr/lib/python2.7/random.py", line 273, in choice
return seq[int(self.random() * len(seq))] # raises IndexError if seq is empty
IndexError: list index out of range

It means that the list you're trying to build - self.urls_on_current_page - is empty.

@echorohit did you decorate your tasks with the @task decorator?
Without that, it never queues up the tasks and hence the error.

Your tasks need to be methods of the WalkPages class.
