how to generate random data in json from python faker?

I want to generate 5 test cases which gives random data in json format as given below.

{
    "password2": "password@123",
    "email": "[email protected]",
    "username": "user123",
    "first_name": "first",
    "last_name": "last",
    "phone":"1234567890",
    "city":"Paris",
    "about":"This is information about developer"
}

The code below gives 5 test cases, but with similar details. I want to generate 5 different test case with all different details. Thank you in advance.

Code:

from faker import Faker
import random


class LoginData:
    fake = Faker()
    password = "password@123"
    email = fake.email()
    username = fake.first_name()
    first_name = fake.first_name()
    last_name = fake.last_name()
    phone = random.randint(9000000000, 9999999999)
    city = fake.city()
    about = "This is a sample text : about"

    def get_json(self):
        p = {
            'password': self.password,
            'email': self.email,
            'username': self.first_name,
            'first_name': self.first_name,
            'last_name': self.last_name,
            'phone': self.phone,
            'city': self.city,
            'about': self.about
        }
        return p


logindata = LoginData()


def input_data(x):
    for i in range(0, x):
        print(logindata.get_json())


def main():
    no_of_input = 5
    input_data(no_of_input)


main()

If I understand correctly, the problem is that you want to generate different data every time. To do that, you need to:

  • Currently the LoginData attributes are generated when the class is defined. If you want them to be different for each instance, make them instance attributes and set them in the __init__() method.

  • You need to create a new LoginData instance in every iteration of the for loop in input_data().

Code:

from faker import Faker
import random


class LoginData:

    def __init__(self):
        fake = Faker()
        self.password = "password@123"
        self.email = fake.email()
        self.username = fake.first_name()
        self.first_name = fake.first_name()
        self.last_name = fake.last_name()
        self.phone = random.randint(9000000000, 9999999999)
        self.city = fake.city()
        self.about = "This is a sample text : about"

    def get_json(self):
        p = {
            'password': self.password,
            'email': self.email,
            'username': self.first_name,
            'first_name': self.first_name,
            'last_name': self.last_name,
            'phone': self.phone,
            'city': self.city,
            'about': self.about
        }
        return p



def input_data(x):
    for i in range(0, x):
        logindata = LoginData()
        print(logindata.get_json())


def main():
    no_of_input = 5
    input_data(no_of_input)


main()

Note that get_json() still returns a Python dict, not JSON. For JSON, you can use the json module in the standard library:

import json

and in get_json()

return json.dumps(p)
