BigQuery

Integration with Google BigQuery using the BigQuery Emulator.

Installation

pip install pytest-databases[bigquery]

The bigquery extra is kept as a compatibility group. Install the BigQuery client that your application already uses.

Usage Example

from google.api_core.client_options import ClientOptions
from google.auth.credentials import AnonymousCredentials
from google.cloud import bigquery

from pytest_databases.docker.bigquery import BigQueryService

pytest_plugins = ["pytest_databases.docker.bigquery"]


def test(bigquery_service: BigQueryService) -> None:
    client = bigquery.Client(
        project=bigquery_service.project,
        client_options=ClientOptions(api_endpoint=bigquery_service.endpoint),
        credentials=AnonymousCredentials(),
    )

    job = client.query(query="SELECT 1 AS one")
    rows = list(job.result())
    assert rows[0].one == 1

Available Fixtures

  • bigquery_image: The Docker image to use for the BigQuery emulator.
  • bigquery_service: A fixture that provides a running BigQuery emulator service.
