A Python package for managing pytest plugins.

Project description

pytest-dynamic-parameterize

A powerful pytest plugin for Python projects, enabling dynamic test parameterization using functions.
Easily generate test parameters at runtime from any function—supporting advanced, data-driven, or config-based testing workflows.


🚀 Features

  • Dynamic Parameterization: Generate test parameters dynamically by referencing a function.
    • Use the @pytest.mark.parametrize_func("function_name") marker on your test.
    • Supports both local and fully-qualified function names (e.g., my_func or my_module.my_func).
    • Supports multiple @pytest.mark.parametrize_func markers on a single test for advanced parameterization.
    • Pass keyword arguments to your parameter function via the marker: @pytest.mark.parametrize_func("my_params", some_param="some_value").
    • Enables:
      • Data-driven tests from config files, databases, or APIs
      • Centralized test data logic
      • Cleaner, more maintainable test code

📦 Installation

pip install pytest-dynamic-parameterize

🔧 Usage

  1. Define a parameter function (must accept a config argument and return a list of tuples or values):
# parameterize_functions.parametrize_functions.my_params.py
def my_params(config, some_param=None) -> list[tuple]:
    if some_param == "special":
        return [(10, 20, 30)]
    return [
        (1, 2, 3),
        (4, 5, 9),
    ]
  1. Mark your test with one or more @pytest.mark.parametrize_func decorators:
import pytest
from tests.parameterize_functions.my_params import my_params


@pytest.mark.parametrize_func("my_params")
def test_add(a, b, expected):
    assert a + b == expected
  • Pass arguments to your parameter function:

    import pytest
    from tests.parameterize_functions.my_params import my_params
    
    @pytest.mark.parametrize_func("my_params", some_param="special")
    def test_add_special(a, b, expected):
        assert a + b == expected
    
  • Use multiple parametrize_func markers for advanced parameterization:

    import pytest
    from tests.parameterize_functions.my_params import my_params
    
    @pytest.mark.parametrize_func("my_params", some_param="special")
    @pytest.mark.parametrize_func("my_params")
    def test_add_multi(a1, b1, expected1, a2, b2, expected2):
      assert a1 + b1 == expected1
      assert a2 + b2 == expected2
    
  • You can also use a fully-qualified function path:

    import pytest
    
    @pytest.mark.parametrize_func("parameterize_functions.parametrize_functions.my_params")
    def test_add(a, b, expected):
        ...
    
  • The function can be imported or defined in the same module.

  • The function should return a list of argument tuples matching the test signature.
