No Locust class found

[alok-nag]

• I installed locustio and wrote a simple locustfile.py to check min_rate/max_rate as given in docs.
• I am using virtualenv and locust --help command works fine and print help.
• locust -V prints Locust 0.7..5

When I start locust using locust -f locustfile.py -H http://docs.locust.io
I get error saying: No Locust class found!

Python version is 2.7.12, running on Ubuntu VM.

Please let me know what needs to be done.

[alok-nag]

Can someone please help?

[aldenpeterson-wf]

what is your locust file?

[alok-nag]

`from locust import Locust, TaskSet, task

class MyTaskSet(TaskSet):
@task
def my_task(self):
print "Executing my task"

class MyLocust(Locust):
task_set = MyTaskSet
min_wait = 5000
max_wait= 50000
`

[aldenpeterson-wf]

I am able to run that fine locally after fixing indentation, can you give more context for why it's not working?

$cat locustfile.py
from locust import Locust, TaskSet, task

class MyTaskSet(TaskSet):
  @task
  def my_task(self):
      print "Executing my task"

class MyLocust(Locust):
  task_set = MyTaskSet
  min_wait = 5000
  max_wait= 50000

This is all I know of.
This file saved as locustfile.py
Python 2.7.12, running in virtualenv on Ubuntu VM.
from virtualenv I run command "locust -f locustfile.py -H http://docs.locust.io" and I get that error after it prints some warnings about using zmq
/ERROR/locust.main: No Locust class found!

What else can I collect - am quite new to this. Evaluating to see if I can use it for my testing of a webapp.

@alok-nag
you closed this issue right after your comment requesting help. If you are still experiencing this and believe it is a real issue with Locust, please re-open (or else nobody will look at it). I will leave it closed until then.

i think locust is reserved keyword for locust file. I try to renaming my test locust file to other, and locust can running.

[uduse]

@elfarqy yep yep. I renamed my file from locust.py to query_locust.py and resolved the problem.

[mrserzhan]

I have the same issue, but in my case python file was the same as directory name. Idk why, but renaming helps

I got this error when copy example from guide in to text editor and save as py file. When white space and tab are mixed this error were shown.

[mishalalex]

I am getting the same error when I tried to run locust on windows. I have corrected the white space and indentation. Still when I tried to execute the command - locust - I am getting the same error
No Locust class found!

Hi I've the same error on Win10.
I use virtualenv and in test1.py there is the "With HTML parsing" in https://locust.io/:
(venv) C:\Users\sgiostra\PycharmProjects\stress_test>locust -f test1.py
and i got:
[2020-05-19 23:17:53,357] BB-168/ERROR/locust.main: No Locust class found!

The examples on https://locust.io hadn't been properly updated after the release of locust 1.0. It has now been fixed!

[StefanoGITA]

I'm on windows and I use locust (pipy locustio) 0.14.6 The example <https://docs.locust.io/en/stable/quickstart.html>on documentation is different and don't show where put the url of the site. Where can I find an example like that on home for locust 0.14.6? Thanks. Stefano G. Il giorno mer 20 mag 2020 alle ore 10:28 Jonatan Heyman < [email protected]> ha scritto:

You can read the docs for 0.14.6 here: https://docs.locust.io/en/0.14.6/index.html

The examples on https://locust.io has been updated for the latest stable version (1.0.1), and the old examples there are gone. Maybe you can find the old examples using WaybackMachine on https://archive.org

[StefanoGITA]

Hi Jonatan now wit 1.0.3 i can use locust on windows too. Wonderful tool, I really appreciate your work. Stefano G. Il giorno ven 22 mag 2020 alle ore 17:50 Jonatan Heyman < [email protected]> ha scritto:
