pytest_param_files 0.1.0

Create pytest parametrize decorators from external files.

pytest-param-files

A small package to create pytest parametrize decorators from external files.

Simply create a text file with the following (dot) format:

[name1] description
.
input content
.
expected output content
,

[name2] description
.
input content
.
expected output content
,

Then, use the with_parameters decorator to create a parametrized test:

from pathlib import Path
from pytest_param_files import with_parameters

import my_function

PATH = Path(__file__).parent.joinpath("test_file.txt")

@with_parameters(PATH, fmt="dot")
def test_function(line, title, description, content, expected):
    assert my_function(content) == expected

and the output will be:

$ pytest -v test_file.py
...
test_file.py::test_function[1-name1] PASSED
test_file.py::test_function[8-name2] PASSED
