pytest-typhoon-config

A pytest plugin that facilitates test parameter configuration at runtime

Features

• 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.

Requirements

• pytest 6+

Installation

You can install pytest-typhoon-config via pip:

pip install pytest-typhoon-config

Usage

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

# myparams.py
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):
    pass

In this example even_values variable will be initialized in myparams.py 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:

pytest --runconfig=myparams.py

The path of this file is evaluated at runtime.
