"""Mock PyPI Server implementation, to use in tests.
|
|
|
|
This module also provides a simple test case to extend if you need to use
|
|
the PyPIServer all along your test case. Be sure to read the documentation
|
|
before any use.
|
|
|
|
XXX TODO:
|
|
|
|
The mock server can handle simple HTTP request (to simulate a simple index) or
|
|
XMLRPC requests, over HTTP. Both does not have the same intergface to deal
|
|
with, and I think it's a pain.
|
|
|
|
A good idea could be to re-think a bit the way dstributions are handled in the
|
|
mock server. As it should return malformed HTML pages, we need to keep the
|
|
static behavior.
|
|
|
|
I think of something like that:
|
|
|
|
>>> server = PyPIMockServer()
|
|
>>> server.startHTTP()
|
|
>>> server.startXMLRPC()
|
|
|
|
Then, the server must have only one port to rely on, eg.
|
|
|
|
>>> server.fulladdress()
|
|
"http://ip:port/"
|
|
|
|
It could be simple to have one HTTP server, relaying the requests to the two
|
|
implementations (static HTTP and XMLRPC over HTTP).
