Features

Create temporary directories on the following filesystems:

Installation

You can install pytest servers via pip from PyPI:

.. code:: console

$ pip install pytest-servers

To use temporary S3 paths:

.. code:: console

$ pip install pytest-servers[s3]

To use temporary Azure paths

.. code:: console

$ pip install pytest-servers[azure]

To use temporary Google Cloud Storage paths

.. code:: console

$ pip install pytest-servers[gcs]

To install all extras:

.. code:: console

$ pip install pytest-servers[all]

Usage

The main fixture provided by pytest-servers provides is tmp_upath_factory, which can be used to generate temporary paths on different (mocked) filesystems:

.. code:: python

def test_something_on_s3(tmp_upath_factory): path = tmp_upath_factory.mktemp("s3") foo = path / "foo" foo.write_text("foo") ...

mktemp supports the following filesystem types:

Some convenience fixtures that wrap tmp_upath_factory.mktemp and return a paths on these filesystems are also available:

The tmp_upath fixture can be used for parametrizing paths with pytest's indirect parametrization:

.. code:: python

@pytest.mark.parametrize("tmp_upath", ["local", "s3", "gcs", "gs"], indirect=True) def test_something(tmp_upath): pass

In order to use real remotes instead of mocked ones, use tmp_upath_factory with the following methods

Versioning support can be used by using the versioning fixture. This is currently supported for s3 and gcs remotes

.. code:: python

using mktemp

def test_something_on_s3_versioned(tmp_upath_factory): path = tmp_upath_factory.mktemp("s3", version_aware=True) assert path.fs.version_aware # bucket has versioning enabled

or, using remote-specific fixtures

def test_something_on_s3_versioned(tmp_s3_path, versioning): assert tmp_s3_path.fs.version_aware # bucket has versioning enabled
