auto-pytest-mg 0.8.0

Awesome `auto_pytest_mg` is a Python cli/package created with https://github.com/TezRomacH/python-package-template

auto_pytest_mg (Automatic pytest Mock Generator)

auto_pytest_mg generates a test skeleton for a given python file. This skeleton includes:

• fixtures that mock all non-standard library imported names
• a boilerplate test for every class method and property
• a boilerplate test for every function
• mocker and mg fixtures for all tests
  • mocker: pytest-mock
  • mg: pytest-mocker-generator
    • If you're unfamiliar with pytest-mock-generator, you can read up on usage information in their README.

It is not auto_pytest_mg's goal to produce the entirety of the test. The creation of test mocks and asserts is delegated to pytest-mocker-generator via the mg fixture and the mg.generate_uut_mocks_with_asserts(...) call.

This package is a static analysis tool and will not execute any of your code.

Usage

# install the package
pip install auto_pytest_mg

# go to project's source root
cd my_project

# pass the file to generate tests for
auto_pytest_mg my_project/my_file.py

Example

Source file located at my_project/my_file.py

# my_project/my_file.py
import requests

class MyClass:

    def __init__(self, a: int):
        self.a = a

    def method(self) -> int:
        return self.a


def get(url: str) -> requests.Response:
    return requests.get(url)

Running auto_pytest_mg my_project/my_file.py will then output to stdout the generated test file:

import pytest

from my_project.my_file import get, MyClass


MODULE_PATH = "my_project.my_file"


@pytest.fixture
def mock_requests(mocker):
    return mocker.patch(f"{MODULE_PATH}.requests")



@pytest.fixture
def my_class(mocker):
    a = mocker.MagicMock()
    return MyClass(a=a)


class TestMyClass:
    def test__init__(self, mocker):
        a = mocker.MagicMock()

        my_class_ = MyClass(a=a)

    def test_method(self, mocker, mg, my_class):
        mg.generate_uut_mocks_with_asserts(my_class.method)

        result = my_class.method()


      
def test_get(mocker, mg):
    url = mocker.MagicMock()
    mg.generate_uut_mocks_with_asserts(get)

    result = get(url=url)
