PyProxyFS 0.8

Simple filesystem abstraction<br /><br />PyProxyFS is a proxy filesystem interface with a native filesystem implementation and a very simple test in-memory filesystem.<br /><br />The aim of pyproxyfs is to provide a filesystem class that you can use for doing much of your file handling... but that can easi;ly be mocked for specific testing purposes.<br /><br />If, instead of using open, os.rename and os.listdir you use the pyproxyfs equivalents you can expect to be able to make a simple filesystem using the builtin TestFS class and write tests around that.<br /><br />For example:<br /><br />def show_conf_files(dirtolist, filesystem=None):<br /> from pyproxyfs import Filesystem<br /> if not filesystem:<br /> filesystem = Filesystem()<br /> files = filesystem.listdir(dirtolist)<br /> import re<br /> cfgpat = re.compile(".*.cfg$")<br /> cfg_files = [fn for fn in files if cfgpat.match(fn)]<br /> return cfg_files<br /><br />this might be your application code.<br /><br />You could then test it relatively simply:<br /><br />def test_show_conf_files():<br /> """<br />>>> test_show_conf_files()<br />['a.cfg', 'b.cfg']<br />"""<br /> from pyproxyfs import TestFS<br /> fs = TestFS({<br /> "somedir/a.cfg": "",<br /> "somedir/a.txt": "",<br /> "somedir/b.cfg": "",<br /> "somedir/run.py": ""<br /> })<br /> return show_conf_files("somedir", filesystem=fs)<br /><br />#md5=0457d51d270d68a47188b77dcdc45e04
