python – 确保所有Django视图返回200？

发布时间：2020-12-16 21:37:53 所属栏目：Python 来源：网络整理

导读：我有很多简单的Django视图,如下所示： @team_leader_requireddef view_all_teams(request): teams = Team.objects.all() template_vars = {'toolbar': 'teams','teams': teams} return render(request,"all_teams.html",template_vars) 我最终写了很多关于表

我有很多简单的Django视图,如下所示：

@team_leader_required
def view_all_teams(request):
    teams = Team.objects.all()

    template_vars = {'toolbar': 'teams','teams': teams}
    return render(request,"all_teams.html",template_vars)

我最终写了很多关于表单的单元测试：

def test_view_all_teams_renders(self):
    user = self.create_team_leader()
    self.log_in(user)

    response = self.client.get(reverse('all_teams'))
    self.assertHttp200(response)

尽管我使用方便的方法来创建用户(例如.create_team_leader)和各种便利断言(例如.assertHttp200),但我的测试中仍然会出现大量重复.

(我的测试很简单,因为我看不到其他任何有用的断言这些视图 – 如果重命名模板,TestCase.assertTemplateUsed会中断,即使视图是正确的.)

很容易错过测试,这让我在重命名模板时没什么信心.有什么方法可以自动生成测试用例吗？像(伪代码)：

for every view in urls:
    if view doesn't take extra arguments:
        test that view returns 200 when a logged in superuser does a GET

编辑

这是我的urls.py中的代表性片段：

urlpatterns = patterns('',url(r'^teams/$','teams.views.view_all_teams',name='all_teams'),url(r'^teams/major/$','teams.views.view_major_teams',name='major_teams'),url(r'^teams/minor/$','teams.views.view_minor_teams',name='minor_teams'),url(r'^teams/(?P<team_id>d+)/$','teams.views.view_team',name='view_team'),url(r'^teams/(?P<team_id>d+)/edit$','teams.views.edit_team',name='edit_team'),url(r'^teams/(?P<team_id>d+)/delete$','teams.views.delete_team',name='delete_team'),

我想自动测试这个列表中的前三个视图.

解决方法

from django.core import urlresolvers
from django.test import TestCase


class SimpleTest(TestCase):
    def test_simple_views(self):
        url_names = [
            'all_teams','major_teams','minor_teams','view_team','edit_team',]

        user = self.create_team_leader()
        self.log_in(user)

        for url_name in url_names:
            try:
                url = urlresolvers.reverse(url_name,args=(),kwargs={})
            except urlresolvers.NoReverseMatch:
                #print('Pass {}'.format(url_name))
                continue

            #print('Try {}'.format(url_name))
            response = self.client.get(url)
            self.assertHttp200(response)

如果所有url模式都有其名称,则可以使用以下代码来定义url_names：

url_names = [p.name for p in teams.urls.urlpatterns]

已知的问题

>如果查看功能失败,您将无法知道哪个视图失败.
>将不会测试失败视图旁边的视图.

另一个处理上述问题的版本.

import unittest

from django.core import urlresolvers
from django.test import TestCase

from teams.urls import urlpatterns


class SimpleTest(TestCase):
    ...

    def setUp(self):
        user = self.create_team_leader()
        self.log_in(user)

    url_names = [p.name for p in urlpatterns]
    vs = vars()
    def make_test_function(idx,url_name,url):
        def  t(self):
            response = self.client.get(url)
            self.assertHttp200(response)
        t.__name__ = 'test_' + idx
        t.__doc__ = 'simple get test for ' + url_name
        return t

    for i,url_name in enumerate(url_names):
        i = str(i)
        try:
            url = urlresolvers.reverse(url_name,kwargs={})
            vs['test_' + i] = make_test_function(i,url)
        except urlresolvers.NoReverseMatch as e:
            vs['test_' + i] = unittest.skip(url_name + ' requires parameter(s) or view not found')(lambda: 0)

    del url_names,vs,make_test_function,
