How to Mock Kubernetes Secret Mounts in Python
Create and inspect a mock Kubernetes secret volume mount using the official client library and unittest.mock.
import json
from kubernetes import client, config, watch
from unittest.mock import Mock, patch
def create_mock_mount_spec():
"""Create a mock Kubernetes secret volume mount."""
mock_client = Mock()
mock_client.api_version = "v1"
mock_client.kind = "Secret"
mock_client.metadata = {"name": "my-secre…How to Smoke Test a Deployment in Python with unittest.mock
Run a post-deploy smoke test by mocking the deployment status check to verify your health-check logic returns PASS/FAIL.
import unittest
from unittest.mock import Mock, patch
class DeploymentService:
def check_status(self):
return "unknown"
def smoke_test_deploy():
service = DeploymentService()
with patch.object(service, "check_status", return_value="healthy") as mock_check:
status = service.check_status()
