An extension for the hypothesis project that enables fully automatic tests for type annotated functions:

from hypothesis_auto import auto_test


def add(number_1: int, number_2: int = 1) -> int:
    return number_1 + number_2


auto_test(add)  # 50 property based scenerios are generated and ran against add
auto_test(add, _auto_runs=1_000)  # Let's make that 1,000

from hypothesis_auto import auto_test


def divide(number_1: int, number_2: int) -> int:
    return number_1 / number_2

auto_test(divide)

-> 1012                     raise the_error_hypothesis_found
   1013
   1014         for attrib in dir(test):

      1 def divide(number_1: int, number_2: int) -> int:
----> 2     return number_1 / number_2

ZeroDivisionError: division by zero


auto_test(divide, _auto_allow_exceptions=(ZeroDivisionError, ))

For the full set of parameters you can pass into auto_test see its API reference documentation.

Why Create hypothesis-auto?

I wanted a no/low resistance way to start incorporating property based tests across my projects. Such a solution, that also encouraged the use of type hints, was a win/win for me.

I hope you too find hypothesis-auto useful!
