Load testing on an API using python

Question

I am currently writing python script for load testing an API.I want to check how many requests can an API take at a time.The API is for registration so I have to send unique parameters everytime.

Is there anyway I could achieve it through locust or any other way?

Any help would be appreciated.

This is my code for registration of single user.

def registration:
    URL = "ip"
    PARAMS = {'name':'test','password':'test1','primary_email':'[email protected]','primary_mobile_number':'9999999999','country_abbrev':'US'} 
    r = requests.post(url = URL,params = PARAMS,auth=HTTPDigestAuth('user', 'pass')) 
    response = r.text 
    print response

Take a look at Faker Python Package. This generates fake data for you whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you.

from locust import HttpLocust, TaskSet, task
class UserBehavior(TaskSet):
    def on_start(self):
        pass  # add code that you want to run during ramp up

    def on_stop(self):
        pass  # add code that you want to run during ramp down

    def registration(self):
        name = fake.first_name()
        last_name = fake.last_name()
        password = ''
        email = name + last_name + '@gmail.com'
        phone = fake.phone_number()
        URL = "ip"
        PARAMS = {'name':name,'password': password,'primary_email': email,'primary_mobile_number':phone,'country_abbrev':'US'} 
        self.client.post(URL, PARAMS)

class WebsiteUser(HttpLocust):
    task_set = UserBehavior
    min_wait = 5000
    max_wait = 9000

To start the load test, run locust -f locust_files/my_locust_file.py --host=http://example.com For more info, visit Locust Quickstart
