pytest-gcs 0.0.3

GCS fixtures and fixture factories for Pytest.

Pytest GCS

This is a pytest plugin in similar vein to pytest-postgres and pytest-kafka.

This would have been much more painful without Mirakuru and fake-gcs-server; this is a simple wrapper around those tools.

Installation

This tool requires you to have a copy of the fake-gcs-server binary somewhere on your path. Depending upon your architecture you'll need a different version of the tool.

wget https://github.com/fsouza/fake-gcs-server/releases/download/v1.47.8/fake-gcs-server_1.47.8_Linux_amd64.tar.gz
tar -xvf fake-gcs-server_1.47.8_Linux_amd64.tar.gz
mv fake-gcs-server /usr/local/bin

To install this library:

pip install pytest-gcs

Demo

# conftest.py
from pytest_gcs.factories import client as gcs_client
from pytest_gcs.factories import proc as gcs_process

# Create a process and a local client that targets that process.
gcs_proc = gcs_process.gcs_proc()
gcslocal = gcs_client.gcslocal("gcs_proc")

# tests/test_gcs.py
from google.cloud import storage
from pytest_gcs.executor.process import GCSExecutor


def test_can_create_gcs_bucket(gcs_proc: GCSExecutor, gcslocal: storage.Client) -> None:
    """MVP to ensure everything works."""
    bucket = "test_base"
    gcslocal.create_bucket(bucket)
    buckets = [x.name for x in gcslocal.list_buckets()]

    assert bucket in buckets
