pytest-parametrize

pytest decorator for parametrizing test cases in a dict-way. It is an alternative for the pytest.mark.parametrize.

Usage

Decorate test function with test cases defined as a dictionary.

Example:

Simple

import pytest
from pytest_parametrize import parametrize

@parametrize(
    {
        "test-case-1": {"a": 1, "b": 2, "c": 3},
        "test-case-2": {"a": 2, "b": 3, "c": 5},
        "test-case-3": [
            {"a": 3, "b": 5, "c": 8},
            {"a": 5, "b": 8, "c": 13},
            {"a": 8, "b": 13, "c": 21},
            {"a": 0, "b": 0, "c": 1, "marks": pytest.mark.xfail},
        ],
    },
)
def test_something(a, b, c):
    assert a + b == c

Or more complex one:

from pytest_parametrize import parametrize

@parametrize(
    {
        "a=1": {"a": 1},
        "a=2": {"a": 2},
    }
)
@parametrize(
    {
        "b=1": {"b": 1},
        "b=2": {"b": 2},
    }
)
def test_parametrize__when_complex_structure(a: int, b: int):
    assert a * b > 0

Description

Decorator takes dict, which:

keys define names of the test cases, and
values define named arguments in dict manner (or list of such dicts), which are passed to the decorated test function.
