how to make nose to log output of cases to separat

I am using nose to run a bunch of test cases. I would like to record output of each case to separate files, and to know result[success/failure] of each case. unfortunately, I can not figure out how to do it with nose. can anybody provide some clues? thank you

Firstly, this sounds like unusual usage, and may indicate that you should rethink your testing scheme.

I can think of a couple of ways to address this. The simplest would be to have each test log itself instead of having nose do it for you. If you have only a few tests, or only care to log the results of a few tests, this would definitely be the way to do it.

A more complex and general approach would be to write a nose plug-in that records the result of each test as it finishes. To do this, you'd want to write a plug-in that implements the afterTest() method.

from nose.plugins import Plugin
import datetime

class SeparateReports(Plugin):
  "Log the results of each test into a separate file."
  def afterTest(self, test):
    logname = test.id() + '.log'
    success = test.passed
    date = datetime.datetime.now()
    # print logname, datetime.datetime.now(), success
    with open(logname, 'a') as log:
        log.write("%s: %s\n" % (date, success))

This will append to a logfile named after your specific test a datestamp and True for success/False for failure. A couple of notes:

See the commented-out line for an example of the results that are printed.
This plug-in will have to be registered by nose; see the docs.
Once registered, the plug-in will have to be enabled; use the commandline option --with-separatereports (automagically generated based on the plug-in name).
This will be pretty slow since it is touching files for every test. You may want an sqlite DB that is open or something like that.
