887910 - mozfile's test_load.py:test_http shouldn't use hardcoded port for http server

Status: RESOLVED FIXED

Description

https://github.com/mozilla/mozbase/blob/master/mozfile/tests/test_load.py#L28

By always instantiating the server with port 8888, we create two problems:

1. If another test wants to grab port 8888 at the same time, it will fail.
2. If you have a server listening on port 8888 when the test runs, it will fail.

The preferred use of mozhttpd is to pass in port 0 (now the default if nothing else specified). Let's fix the test to do that, and use the new get_url method (http://mozbase.readthedocs.org/en/latest/mozhttpd.html#mozhttpd.MozHttpd.get_url) to get the file url below while we're at it.

Patch to remove hard-coded port usage

I've removed the port parameter specified in the test entirely, since 0 is now the default and since we're using get_url we should not really be worried about the specified port, will that be okay or should I specify port=0 explicitly?

Looks good with some minor requests for changes. r+ with those applied.

I would just collapse the code + comments into:

content = load(httpd.get_url()).read()

It's pretty obvious what's going on without the comment.

Remove this line.

Oh, and no, there's no need to specify the port anymore.
