How to package locust file with pyinstaller - locust

Question

In virtual environment I installed locust.
I want to create distributable package so any user can run load tests.
I used pyinstaller.
The exe file is created but when I run it nothing happens.
from locust import HttpUser, TaskSet, task
import orjson as json
def create_post(self):
paramsDict = {}
paramsDict = json.loads('{ ...myjson.. }')
params = json.dumps(paramsDict) #for orjson
headers = {'content-type': 'application/json','Accept-Encoding':'gzip'}
response = self.client.post("/",data= params, headers=headers, name = "Post query")
print(f'response -> {response}')
class WebsiteUser(HttpUser):
tasks = [create_post]
I used locust as library as Axel pointed.
I build with pyinstaller and tests runs just web page is not displayed
I build with pyinstaller but web did not appear `response -> <Response [200]>

The template needs to be included in build.
Into spec file I added into data section as well as static with java scripts and css
datas=[('<path>\\Lib\\site-packages\\locust\\templates', 'locust\\templates'),('<path>\\Lib\\site-packages\\locust\\static', 'locust\\static')],
With Inno Setup I added also those to folders to be in same folder as executable.
And web page is displayed.

All depend on how are you expecting to get your test executed and what are your really packing. Locust have different ways of use. Assuming that you wanna pack your test file as an executable file you may need to include in your file a main entrypoint that use locust as a library
If you are packing the locust itself and the virtualenv including your test file you may need to specify how to run locust as a command and pass your test file as a command line argument
