A Typhoon HIL plugin that facilitates test parameter configuration at runtime

Project description


A pytest plugin that facilitates test parameter configuration at runtime


  • specify test parameters in a python module, just like any other
  • choose which module to use at runtime

This way you can define different parameter sets for the same test suite and choose them at runtime.


  • pytest 6+


You can install pytest-typhoon-config via pip:

pip install pytest-typhoon-config


Create a test parameter definition file as a Python module, such as this:

import numpy as np

a_list = [277.0, 278.0]
a_numpy_range = np.arange(58, 63, 0.2)
even_values = [v for v in range(20) if v % 2 == 0]

class StayConnected:
    some_list = [22, 45, 85, 95]
    some_param = 0.95

All module attributes will be injected at runtime in tytest.config.runtime_settings.Config class. They will be available as class-level attributes of Config. That means you can use them like this:

from tytest.runtime_settings import Config as C

@python.mark.parametrize('param1', C.even_values)
def test_something(param1):

In this example even_values variable will be initialized in module, and then injected into Config class. It is available in all test code as Config.even_values.

This way you can create different python modules with the same variables, having different values, and then choose which module to use when invoking pytest. For example:


The path of this file is evaluated at runtime.


Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.
