I wrote the below code

    def decorator(caller):
        if inspect.isclass(caller):
            old_setup = getattr(caller, 'setUp', None)
            def setUp(self, *args, **kwargs):
                if (old_setup is not None):
                    old_setup(self, *args, **kwargs)
                if (not hasattr(self, 'run_function')):
                    raise RuntimeError("{0}    does    not    have    the    'run_function'    method    which    is    necessary    to    collect    the    loaded    modules".format(self.__class__.__name__))
                not_found_modules = self.run_function('runtests_helpers.modules_available', names)
                if not_found_modules:
                    if (len(not_found_modules) == 1):
                        self.skipTest('Salt    module    {0!r}    is    not    available'.format(not_found_modules[0]))
                    self.skipTest('Salt    modules    not    available:    {0!r}'.format(not_found_modules))
            caller.setUp = setUp
            return caller
        @functools.wraps(caller)
        def wrapper(cls):
            if (not hasattr(cls, 'run_function')):
                raise RuntimeError("{0}    does    not    have    the    'run_function'    method    which    is    necessary    to    collect    the    loaded    modules".format(cls.__class__.__name__))
            for name in names:

            return caller(cls)
        return wrapper
    return decorator
