我刚刚在django上开了一个小应用程序。目前,它的目标只是管理测试人员(即用户)和团队。这是我的model.py:

from django.db import models

class Team(models.Model):
    name = models.CharField(max_length=200)
    def __unicode__(self):
        return self.name
    def get_testers(self):
        return self.tester_set.all()

class Tester(models.Model):
    team = models.ForeignKey(Team)
    visa = models.CharField(max_length=3)
    privileged = models.BooleanField()
    def __unicode__(self):
        return self.visa

我正在尝试为“get_testers”函数编写测试。 这是:

from models import Team, Tester
def testTeamGetTesters_test():
    t = list(Team.objects.get(id=2L).get_testers())

    a = Tester(visa = 'a', privileged = True)
    b = Tester(visa = 'b', privileged = True)

    assert(t[0].visa == a.visa and t[0].privileged == a.privileged and t[1].visa == b.visa and t[1].privileged == b.privileged)

但是当我跑步时:

$ python manage.py test tmg

我收到此错误:

nosetests --verbosity 1 tmg
E
======================================================================
ERROR: tempsite.tmg.tests.testTeamGetTesters_test
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/nose/case.py", line 183, in runTest
    self.test(*self.arg)
  File "/home/charlie/code/tempsite/../tempsite/tmg/tests.py", line 8, in testTeamGetTesters_test
    t = list(Team.objects.get(id=2L).get_testers())
  File "/usr/lib/pymodules/python2.6/django/db/models/manager.py", line 132, in get
    return self.get_query_set().get(*args, **kwargs)
  File "/usr/lib/pymodules/python2.6/django/db/models/query.py", line 341, in get
    % self.model._meta.object_name)
DoesNotExist: Team matching query does not exist.

所以,我写了几乎相同的测试,但直接可以运行:

from models import Team, Tester

t = list(Team.objects.get(id=2L).get_testers())

a = Tester(visa = 'a', privileged = True)
b = Tester(visa = 'b', privileged = True)

print "%r" % (t[0].visa == a.visa and t[0].privileged == a.privileged and t[1].visa == b.visa and t[1].privileged == b.privileged)

......当我跑的时候:

$ python tests.py
True

这非常令人困惑......我检查了数据库,对象都完美检索,但我仍然收到此错误...

答案 0 :(得分:1)

您是否在测试中的某处创建了ID为2的Team对象?不要忘记测试从空白数据库开始。
