Provides path for uniform access to test resources in isolated directory

pytest-resource-path

Provides path for uniform access to test resources in isolated directory

Features

Let's isolate test resources from test code

The test which use test resource is not so many. If we place test resource with test code, these resources will fill the display area of explorer. Wouldn't it be more productive if the files or directories which is not related with almost tests wasn't usually displayed?

pytest-resource-path provides path for uniform access to test resources in isolated directory.

This pytest plugin assumes that test resource is placed under testresources directory directly under tests. (Don't worry, you can customize these directory names by pytest.ini)

tests/
+-- some_test_package/
|   +-- some_test_module.py
+-- testresources/
    +-- some_test_package/
        +-- some_test_module/

Installation

You can install "pytest-resource-path" via pip from PyPI:

pip install pytest-resource-path

Usage

Basic

You can use fixture resource_path which is pathlib.Path instance (absolte path).

def test_method(resource_path):
    text_test_resource = (resource_path / 'test_resource.txt').read_text()

When assume that above test_method is in tests/some_tests_package_some_test_module.py, you have to place test_resource.txt following directory:

tests/
+-- some_test_package/
|   +-- some_test_module.py
+-- testresources/
    +-- some_test_package/
        +-- some_test_module/
            +-- test_method/
                +-- test_resource.txt

If you want to omit directory per method, you can do:

def test_method(resource_path):
    text_test_resource = Path(f'{resource_path}.txt').read_text()

Note that the class name is not used in the path since It felt redundant in design.

Get path to test resources root directory

You can use fixture resource_path_root which is pathlib.Path instance (absolte path) pointing to testresources.

def test_method(resource_path_root):
    text_test_resource = (resource_path_root / 'test_resource.txt').read_text()

tests/
+-- some_test_package/
|   +-- some_test_module.py
+-- testresources/
    +-- test_resource.txt

This fixture may be your help duaring migration period of directory structure. Or, may be usiful to preapare common directory with some of tests.

def test_method(resource_path_root):
    text_test_resource = (resource_path_root / 'common/test_resource.txt').read_text()

tests/
+-- some_test_package/
|   +-- some_test_module.py
+-- testresources/
    +-- common/
        +-- test_resource.txt

How to customize directory names

To traverse directory structure, this plugin requires to fix directory names.

By default:

directory	requires to be named
Root directory of tests	tests
Root directory of test resources	testresources

You can customize these required names by pytest.ini

Ex:

[pytest]
resource-path.directory-name-tests = integrationtests
resource-path.directory-name-test-resources = data

Above customize fits following directory strucure:

integrationtests/
+-- some_test_package/
|   +-- some_test_module.py
+-- data/
    +-- some_test_package/
        +-- some_test_module/
