How to Mock a Chunked Encoding Streaming Response in Python
Build a local mock HTTP server with Python's http.server that streams a chunked-encoded response with a 0.5s delay per chunk.
from http.server import BaseHTTPRequestHandler, ThreadingHTTPServer
import time
class ChunkedHandler(BaseHTTPRequestHandler):
protocol_version = "HTTP/1.1"
def do_GET(self):
self.send_response(200)
self.send_header("Content-Type", "text/plain")
self.send_header("Transfer-Encoding", "c…How to mock Server-Sent Events (SSE) in Python
A minimal HTTP server that streams Server-Sent Events to clients, perfect for testing and development.
from http.server import HTTPServer, BaseHTTPRequestHandler
import threading
import time
MESSAGES = iter([
"data: Hello world\n\n",
"data: Second message\n\n",
"event: custom\n",
"data: Custom event payload\n\n",
"data: Final message\n\n"
])
