Setup Locust (Python/load testing) on Windows

I recently used Locust, a load testing tool that lets you write intuitive looking Python code to load test your web applications. I did not follow Locust’s install guide and instead just tried a ‘pip install locustio’. I ended up running into some issues that were not easy to Google about. So I thought I would document the problems I faced along with there solution over here.


Getting setup with Locust on Windows

If you have not already tried installing Locust, follow this short and handy guide. It will help you avoid the problems I faced.

1. Use Python 2.7.x where x >=4. I upgraded my Python to 2.7.11.
2. pip install pyzmq
3. pip install locustio
4. Test your installation by opening up a command prompt and typing locust.--help You should see no errors or warning – only the usage and help should be printed out on your console.


Locust install issues and solutions

When I installed Locust for the first time, I missed steps 1 and 2 in the section above. So I ran into a couple of errors.

1. ImportError: DLL load failed

from gevent.hub import get_hub, iwait, wait, PYPY
File “c:\python27\lib\site-packages\gevent\hub.py”, line 11, in
from greenlet import greenlet, getcurrent, GreenletExit
ImportError: DLL load failed: The specified procedure could not be found.

I got this error because I had Python 2.7.2 (python –version) and Locust needs at least Python 2.7.4. To solve this issue, upgrade your Python version. I ended up installing Python 2.7.11.

2. UserWarning: WARNING: Using pure Python socket RPC implementation instead of zmq

c:\python27\lib\site-packages\locust\rpc__init__.py:6: UserWarning: WARNING: Using pure Python socket RPC implementation instead of zmq.

I got this warning when running the command ‘locust –help’ to test my setup. The warning comes with a helpful recommendation to install pyzmq. I installed pyzmq (pip install pyzmq) and the error went away.

3. pip install locustio gives error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat).

I got the below error when install locust using pip install locustio

building ‘gevent.corecext’ extension
error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat).

I tried installing “gevent” alone using pip install gevent, but got the same error

After bit of searching i installed “gevent” from unofficial windows Binaries for Python Extension Packages.
Download the whl file as per your os combination. I downloaded gevent-1.1.1-cp27-cp27m-win32.whl file.
open command prompt in the directory where you have downloaded whl file and run the below command.

python -m pip install gevent-1.1.1-cp27-cp27m-win32.whl

After that i was able to install locust successfully.


My thoughts on Locust as of May, 2016

A random collection of my thoughts having explored Locust for a little bit.

1. This tool is worth exploring deeper. This is the first load testing tool that I found intuitive.
2. Locust lets me reuse the API checks that I anyway write as part of testing a web application
3. I liked Locust’s documentation. I found the documentation very, ummm, Pythonic! Clearly they have put in effort into making the documentation useful.
4. I got a useful, working prototype for a real world problem in less than a weekend
5. I don’t know how powerful their http client (the one you use to make requests) is … so we may trip up at login for some clients.
6. I hated the way they do not have an automatic ‘end’ to any test – but that is a minor complaint
7. With respect to the resources (memory, CPU) on the client machine, locust swarms scale so much better than Qxf2’s map-reduce solution (think 25:1)
8. There is a limit of 1024 locusts per swarm that maps to the maximum number of files that can be open on Windows. But their documentation warns you about this beforehand. You can increase this number, if needed, on your OS.
9. Their reporting is not persistent or stored


Qxf2 will be exploring this tool over the coming months. I want to try more complex login scenarios, nested tasks and distributed swarms.

I want to find out what conditions produce remarkable software. A few years ago, I chose to work as the first professional tester at a startup. I successfully won credibility for testers and established a world-class team. I have lead the testing for early versions of multiple products. Today, I run Qxf2 Services. Qxf2 provides software testing services for startups. If you are interested in what Qxf2 offers or simply want to talk about testing, you can contact me at: mak@qxf2.com. I like testing, math, chess and dogs.

    Hello, everyone
    I need to get your advice. I use Win 10 and when I try to perform “pip install locustio” I get an error:
    “Failed building wheel for gevent
    Running setup.py clean for gevent
    Failed to build gevent
    Installing collected packages: gevent, locustio
    Running setup.py install for gevent … error”
    If I try to perform “pip install gevent” I get the same error.
    What can I do for installing locustio?

      Hi,

      Have you tried installing Microsoft Visual C++ 14.0 as the error in the last line points to it?
      Let me know if that helps.

            Hi,

            Our blog talks about python verison2.7. So I have just checked the official documentation https://docs.locust.io/en/stable/installation.html
            I have created python3 environment and activated it. Then ran the pip install locust command in that environment. I am able to get it installed.

            You may want to try from your python3 environment. Also, I found in their documentation under Installing Locust on Windows – they have given the link to download pre-built files. Check the files https://www.lfd.uci.edu/~gohlke/pythonlibs/

            Regards,
            Rohini

    Thanks Rohini,

    But it brings us back to the first case.
    I have already installed binary packages using the https://www.lfd.uci.edu/~gohlke/pythonlibs/
    and even installed ll numpy+mkl alongwith the following binary packages
    pyzmq -18.10 win 32
    gevent 1.5a2 win 32
    greenlet 0.4.15 win 32

    Error keeps on reappearing against geventhttpclient

    I’m using windows 10, with intel core i7 ,
    I believe I shouldn’t install nothing related to amd64 , right?

    I tried to manually instal gevent and received this error msg:
    C:\Users\jovan\Downloads>python -m pip install gevent-1.5a2-cp38-cp38-win_amd64.whl
    ERROR: gevent-1.5a2-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.

    I just confrmed my system type is x64. I believe that everything that I installed was donwloaded as x64. I can’t understand why I’m receiving this error.

    I already downloaded visual studio and visual c++ build tools with visual studio.
    but I’m still receiving this error:

      Jovan,

      Can you try installing the previous version of gevent and see if you are able to install?
      gevent‑1.4.0‑cp37‑cp37m‑win_amd64.whl Or you can also try below steps:

      1. Create a new python 3 environment and activate it
      2. Download the latest binary for gevent from the unofficial windows Binaries.
      3. python -m pip install gevent-1.5a2-cp38-cp38-win_amd64.whl

      Hope this helps !

        but doing this… what python version will I be working with?
        right now, I’m able to work with Pythin 7 and locust 0.14.5
        but I can feel locust is not working fine to me.
        I think that locust executes auto-update to this latest version, when installed…

        I don’t think that installing Python 3, will work better than it’s working now to me.

          Hi, Can you try using a Virtual Environment and specifically try with Python 3 (its been tested and worked with that). Also, you try pip install locust==0.14.5 to install a selected version.
