[Python] Using locust with pytest

I am trying to run locust using pytest. I have created this python file but it is not showing any output. pytest doesnot collect the test. How can I use locust with pytest

from locust import HttpUser, TaskSet, task
class WebsiteTasks(TaskSet):
def on_start(self):
self.index()

@task(2)
def index(self):
self.client.get("/")

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


class WebsiteUser(HttpUser):
task = WebsiteTasks
host = "localhost:5000"
min_wait = 1000
max_wait = 5000


When I run pytest locust_test.py this is the output:

================================================================ test session starts ================================================================
