testhttpserver is a simple HTTP server that will respond to a single HTTP request and record some of the data. It is still an early version and doesn't do everything you probably want.
pip install testhttpserver
Using in your tests
To create a test server import the server
from testhttpserver import Server
And then create a new instance including the port, response status and content.
server = Server(8000, response_status=200, response_content='Content')
After you make your request to http://localhost:8000/ . If you POST to the server it will have post_headers and post_content available.
When you are done remember to join()!
See tests/test_server.py for an example!
