我有两个测试类(TrialTest1和TrialTest2)写在两个文件(test_trial1.py和test_trial2.py)中大多数相同(唯一的区别是类名):

from twisted.internet import reactor
from twisted.trial import unittest


class TrialTest1(unittest.TestCase):

    def setUp(self):
        print("setUp()")

    def test_main(self):
        print("test_main")
        reactor.callLater(1, self._called_by_deffered1)
        reactor.run()

    def _called_by_deffered1(self):
        print("_called_by_deffered1")
        reactor.callLater(1, self._called_by_deffered2)

    def _called_by_deffered2(self):
        print("_called_by_deffered2")
        reactor.stop()

    def tearDown(self):
        print("tearDown()")

当我完全运行每个测试时,一切都很好.但是当我启动它时,我有以下输出:

setUp()
test_main
_called_by_deffered1
_called_by_deffered2
tearDown()
setUp()
test_main
tearDown()
