fakebigtable

A mock implementation of Google Cloud Bigtable client for testing for when the overhead of using the emulator is too much for a small project. Unit tests are written to prove emulator parity. We use the emulator so you don't have to.

Install

pip install fakebigtable

Usage with pytest

import pytest
from google.cloud import bigtable
from fakebigtable import FakeBigtableClient

@pytest.fixture(autouse=True)
def mock_bigtable(monkeypatch):
    monkeypatch.setattr(bigtable, "Client", FakeBigtableClient)

def test_bigtable_operations():
    client = bigtable.Client(project="test-project")
    instance = client.instance("test-instance")
    table = instance.table("test-table")
    # Perform operations on table

Usage with unittest

import unittest
from unittest.mock import patch
from google.cloud import bigtable
from fakebigtable import FakeBigtableClient

class TestBigtableOperations(unittest.TestCase):
    @patch('google.cloud.bigtable.Client', FakeBigtableClient)
    def test_bigtable_operations(self):
        client = bigtable.Client(project="test-project")
        instance = client.instance("test-instance")
        table = instance.table("test-table")
        # Perform operations on table
