wsgi_intercept installs a WSGI application in place of a real URI for testing
Description
It installs a WSGI application in place of a real URI for testing.
Testing a WSGI application normally involves starting a server at
a local host and port, then pointing your test code to that address.
Instead,this library lets you intercept calls to any specific host/port
combination and redirect them into a `WSGI application`_ importable by
your test program.
