I wrote the below code

    def _deco_wrapper(f):
        @with_tmpdir
        @wraps(f)
        def wrapper(self, tmp, *args, **kwargs):
            th = None
            phase = dict()
            try:
                startparams = _start_params(tmp, logtarget='INHERITED', **startextra)
                th = Thread(name='_TestCaseWorker', target=self._testStartForeground, args=(tmp, startparams, phase))
                th.daemon = True
                th.start()
                try:
                    Utils.wait_for((lambda : (phase.get('start', None) is not None)), MAX_WAITTIME)
                    self.assertTrue(phase.get('start', None))
                    self._wait_for_srv(tmp, True, startparams=startparams)
                    DefLogSys.info('===    within    server:    begin    ===')
                    self.pruneLog()
                    return f(self, tmp, startparams, *args, **kwargs)
                finally:
                    DefLogSys.info('===    within    server:    end.        ===')
