Pytest Docker MongoDB

Provides fixtures for mongodb instances running in docker.

Usage

Provided is the db fixture which gives you an motor test database instance for mongodb.

@pytest.fixture
def db_with_schema(db_mongodb):
    fill_database(db_mongodb)
    return db

Inside docker compose

This package also supports starting mongodb from pytest which itself is running inside a container.

Included is a docker-compose file compatible with Google Cloud Build, this can be used by passing the command line argument --in-docker-compose=cloudbuild.

In order to override the location of the docker-compose.yml you should write a docker_compose_files fixture.

@pytest.fixture(scope="session")
def docker_compose_files(in_docker_compose, pytestconfig):
    # `in_docker_compose` gives you the value of the command line argument
    # you can use it to pick the location of the file
    # The following, for example, is used in this package
    dc_type = f".{in_docker_compose}" if in_docker_compose else ""

    dc_file = f"docker-compose{dc_type}.yml"
    return [os.path.join(os.path.dirname(__file__), dc_file)]
