How to Mock HTTP Responses to Verify HSTS Headers in Python
This code demonstrates how to use unittest.mock to intercept and capture HTTP response headers, specifically the Strict-Transport-Security header, from a mocked HTTPServer handler for security validation.
from http.server import BaseHTTPRequestHandler, HTTPServer
from unittest.mock import patch
class StrictTransportMock(BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header("Strict-Transport-Security", "max-age=31536000; includeSubDomains")
self.end_headers()
…How to Test X-Content-Type-Options nosniff in Python with Mocks
Mock httpx responses and verify that a server's X-Content-Type-Options header includes nosniff to prevent MIME sniffing.
import httpx
from unittest.mock import Mock, patch
def fetch_headers(url: str) -> dict:
response = httpx.get(url)
return dict(response.headers)
def mock_nosniff_check(response) -> bool:
content_type = response.headers.get("content-type", "")
x_content_type_options = response.headers.get("x-content-ty…Browse by section
