No Locust class found!

Describe the bug

Cannot run simple locust example

Expected behavior

The test should run - not sure what to expect since I’ve never seen a successful example

Actual behavior

I received the error:

[2020-04-09 14:52:59,330] sami/ERROR/locust.main: No Locust class found!

Steps to reproduce

1. Install virtualenv && activate virtualenv venv --python python3 source venv/bin/activate

2. Install locust

   pip3 install locust

3. Create a locustfile called “locustfile.py” with content

import random
from locust import HttpLocust, task, between

class WebsiteUser(HttpLocust):
    wait_time = between(5, 9)

    @task(1)
    def index(self):
        self.client.get("/")

1. Run it and see error:

> locust --host=https://google.com --locustfile locustfile.py
[2020-04-09 14:56:22,097] sami/ERROR/locust.main: No Locust class found!

Environment

• OS: 18.04.4 LTS
• Python version: Python 3.7.3
• Locust version: locust 0.14.5
• Locust command line that you ran: locust --host=https://google.com --locustfile locustfile.py
• Locust file contents (anonymized if necessary):

import random
from locust import HttpLocust, task, between

class WebsiteUser(HttpLocust):
    wait_time = between(5, 9)

    @task(1)
    def index(self):
        self.client.get("/")

yes you are right - thanks for the clarification

For anyone else reading this, please look at the following reference code that works for locust 0.14.5

from locust import HttpLocust, TaskSet, task, between

class UserBehaviour(TaskSet):
    @task(1)
    def index(self):
        self.client.get("/")


class WebsiteUser(HttpLocust):
    task_set = UserBehaviour
    wait_time = between(5, 9)

Oh, nice catch! I have actually been wondering why so many people have referred to the /latest/ docs instead of /stable/ when we’ve set stable as default in Readthedocs. Now I have the answer 😃.

Fixed now!
