start/stop WSGI applications in the background for functional testing
wsgi-liveserver provides a simple LiverServerTestCase class that can be used to help start a web server in the background to serve a WSGI compliant application for use with testing. Generally it will be used in conjuction with something like Selenium to perform a series of functional tests using a browser.

Installation and Dependencies
Install wsgi-liveserver with pip install wsgi-liveserver or just download wsgi_liveserver.py and place it in your project directory. There are no dependencies other than the Python Standard Library.
The wsgi-liveserver LiveServerTestCase can be used instead of unittest.TestCase for any tests that require a running web server. Simply define a create_app() method that returns the WSGI application that you want to have started up in the background, then write your tests as normal. LiveServerTestCase will handle starting and stopping the server for you.
By default LiveServerTestCase will attempt to listen on the first available port in the range 8080-8090 (inclusive). If you wish the LiveServer to attempt to listen on a different range of ports this can be done by setting the port_range class attribute (see the example below).
The following is a very basic example of using wsgi-liveserver with the wsgiref demo_app:
import unittest from wsgiref.simple_server import demo_app from selenium import webdriver from wsgi_liveserver import LiveServerTestCase class SimpleTest(LiveServerTestCase): port_range = (9001, 9010) # default is (8080, 8090) def create_app(self): return demo_app def setUp(self): self.driver = webdriver.Firefox() def tearDown(self): self.driver.close() def test_page_title(self): self.driver.get(self.url_base()) self.assertTrue('Hello world!' in self.driver.page_source) if __name__ == '__main__': unittest.main()
