Project description

pytest-datadir

pytest plugin for manipulating test data directories and files.

Build Status PyPI CondaForge Python Version Code style: black

Usage

pytest-datadir will look up for a directory with the name of your module or the global 'data' folder. Let's say you have a structure like this:

.
├── data/
│   └── hello.txt
├── test_hello/
│   └── spam.txt
└── test_hello.py

You can access the contents of these files using injected variables datadir (for test_ folder) or shared_datadir (for data folder):

def test_read_global(shared_datadir):
    contents = (shared_datadir / "hello.txt").read_text()
    assert contents == "Hello World!\n"


def test_read_module(datadir):
    contents = (datadir / "spam.txt").read_text()
    assert contents == "eggs\n"

pytest-datadir will copy the original file to a temporary folder, so changing the file contents won't change the original data file.

Both datadir and shared_datadir fixtures are pathlib.Path objects.
