Getting blank xunit result file(xml) after using nose.core.TestProgram?

[mountain]

I am using this code and I am getting xml file with this entry only ?

and I am using python v2.7 and nosetests v1.3.7

   

 <?xml version="1.0" encoding="UTF-8"?><testsuite name="nosetests" tests="0" errors="0" failures="0" skip="0"></testsuite>

My code is

   

    #!/usr/bin/env python
   
    from nose.suite import ContextSuite
    from nose.plugins.xunit import Xunit
    from nose.plugins.plugintest import run_buffered as run
    from nose.plugins.skip import SkipTest, Skip
    import fnmatch
    import os
    from nose.loader import TestLoader
    from nose.core import TestProgram
   
    file_pattern = 'test_*.pyc'
    suite = ContextSuite()
    for root, dir_names, file_names in os.walk('.'):
        for file_name in file_names:
            if fnmatch.fnmatch(file_name, 'test_*.py'):
                file_pattern = 'test_*.py'
                break
        path = 'ksa.tests.'
        if root != '.':
            path += root.replace('/', '.')
            path = '{0}.'.format(path.replace('...', '.'))
        for test_case in fnmatch.filter(file_names, file_pattern):
            modname = path + os.path.splitext(test_case)[0]
            module = __import__(modname, globals(), locals(), ['1'])
            suite.addTest(TestLoader().loadTestsFromModule(module))
    outfile = os.path.join(os.path.dirname(__file__), 'nosetests.xml')
    argv = ['nosetests', '-v', '--with-xunit',
            '--xunit-file=%s' % outfile]
    #run(argv=argv, plugins=[Xunit(), Skip()], suite=suite)
    TestProgram(suite=suite, plugins=[Xunit(), Skip()], argv=argv)

So can you please tell what I am doing wrong here ?

Thanks for your consideration :)
