python - Django 测试模型属性

Question

下面是我当前的 coverage.py 报告的屏幕截图。

我不确定如何100% 覆盖此模型。如何测试第 13-20 行？在我的 tests_model.py 中，我假设通过创建一个实例来覆盖它。但事实并非如此。

# Core Django imports
from django.test import TestCase

# Third-party app imports
import nose.tools as noz
from model_mommy import mommy
from model_mommy.recipe import Recipe, foreign_key


# app imports
from ..models.company import Company
from testapp.apps.profiles.models.appUserModel import AppUser

class CompanyModel(TestCase):
    def setUp(self):
        self.company = mommy.make(Company)
        noz.assert_true(isinstance(self.company, Company))


    def test_company_user_count_is_0(self):
        company = mommy.make(Company)
        noz.assert_equal(company.company_user_count(), 0)

    def test_company_user_count(self):
        # Relationship can be one-to-many with users.
        company = mommy.make(Company)
        user1, user2 = mommy.make(AppUser, _quantity=2)
        company.users.add(user1)
        company.users.add(user2)
        noz.assert_equal(company.company_user_count(), 2)


    def test_company_unicode(self):
        noz.assert_equal(self.company.__unicode__(), self.company.name)

我试图在同一个测试文件中测试每个属性自己的属性，例如...

def test_name(self):
    company = mommy.make(Company, name="Test Name")
    noz.assert_equal(company.name, "Test Name")

但这对我的覆盖率分数没有任何影响。

根据评论我也试过这个:

def test_name(self):
    company = mommy.make(Company)
    company.name = "Test"
    company.save()
    noz.assert_equal(company.name, "Test")

但同样，这对分数没有影响。

这些是我的测试设置...

INSTALLED_APPS += (

    'django_nose',
    'django_coverage',
    'django_extensions',

)

TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'

NOSE_ARGS = [
    '--with-coverage',
    '--cover-package=testapp.apps.profiles,testapp.apps.referrals',
    '--cover-html'

]

控制台输出:

> python manage.py test

Answer 1

参见 this issue在 django_coverage 项目页面上。

另外，看看 coverage.py official FAQ ，尤其是这个:

Q: Why do the bodies of functions (or classes) show as executed,
   but the def lines do not?

似乎覆盖机制是在您的模型实际导入后启动的。

尝试回到标准 Django 测试场景(使​​用内置测试运行器)并通过发出以下命令手动运行覆盖:

coverage run --source='.' ./manage.py test
coverage report
coverage html

查看报告是否不同。
