A fixture generator based on type annotations.

Fistro

A fixture generator based on type annotations.

Examples

from dataclasses import dataclass
from datetime import datetime, date
from typing import List

from fistro.fistro import generate


@dataclass
class Employee:
   id: int
   birthday: date
   last_access: datetime
   password: str
   number_plates: List[int]
   name: str = 'Carlos Sánchez'

employee = generate(Employee)()
print(employee)

It will show something like this:

Employee(id=5809893100, birthday=datetime.date(559, 3, 6), last_access=datetime.datetime(1053, 8, 29, 19, 11, 14), password="iFZ>?)V0'", number_plates=[85863115, 3528889142, 2818728907, 6043092538, 4985672707], name='Carlos Sánchez')

generate function can be called with to_json or to_dict boolean pararameters to return json or dict representation respectively:

class AreaOfCompany(BaseModel):                     
    enable: bool                                    
    riskOwner: str                                  
    description: str                                
    name: str                                       
    code: str
    
print(fistro.generate(AreaOfCompany, as_dict=True))

>>> {'enable': True, 'riskOwner': 'LqPqS\x0c{kZ', 'description': 'k1917GvOV', 'name': '`;ORxzQ7i', 'code': 'w2 |P\rEps'}

print(fistro.generate(AreaOfCompany, as_json=True))

>>> {"enable": true, "riskOwner": "h@Ij34u?H", "description": ",R,G%0<y#", "name": "K4.\u000b:lK!}", "code": "fvitVYrk3"}

Another useful functions are generate_from_json and get_class_body_from_annotations:

from json import loads

from fistro.fistro import generate_from_json, get_class_body_from_annotations

specific_str = """{

specific_json = loads(specific_str)

the_class = generate_from_json(specific_json)
print(get_class_body_from_annotations(the_class.__annotations__))
