Savida - Testing HTTP Server Fixture

Project description

Savida Testing Web Server Fixture

Savida is a testing-oriented HTTP server wrapper. It allows to easily launch a Web server during an automated test, define its behavior (i.e. how to respond to different requests) and shut it down easily when the test ends.

This is useful when testing complex HTTP-client based systems - for example at Shoppimon it is used to test our Web monitoring system infrastructure, which needs to access Websites using a complex browser and return different information based on entire page behaviors or even entire passes through the site.

Testing such systems is not possible using current mock HTTP client libraries or naive test server implementations, and this is why we created Savida.

Note that while the examples below refer to py.test, this module is in no way tied to a specific testing framework or methodology.


In testing frameworks like py.test, usage usually looks something like:

from savida.fixture import http_server

def test_my_browser_works():
    # Set up the server with a static document root directory
    with http_server(document_root='fixtures/webroot') as server:

        # Return 404 on /js/main.js even if it exists in our docroot
            status=404, response='Gone to Lunch')

        # Wait 10 seconds before responding to /slow.php


        response = requests.get(server.url + '/js/main.js')
        assert response.status_code == 404

Usage in module setup / teardown functions





  • Add documentation
  • Clean up API, replace wait method with something more concise
  • Add support for matching based on HTTP method
