Integration Testing with Mocked Activities

Comprehensive patterns for testing workflows with mocked external dependencies, error injection, and complex scenarios.

Activity Mocking Strategy

Purpose: Test workflow orchestration logic without calling real external services

Basic Mock Pattern

import pytest
from temporalio.testing import WorkflowEnvironment
from temporalio.worker import Worker
from unittest.mock import Mock

@pytest.mark.asyncio
async def test_workflow_with_mocked_activity(workflow_env):
    """Mock activity to test workflow logic"""
