Question

我的tests.py

中有以下内容

class TestSugar(TestCase):
    def test_empty_sugar_applicants(self):
        Sugar_Applicant.objects.using('sugarcrm').all().delete();
        number_of_sugar_applicants = Sugar_Applicant.objects.using('sugarcrm').filter(deleted=0).count()
        self.assertEqual(number_of_sugar_applicants, 0)

应该像我的代码的其他区域一样调用sugarcrm数据库并访问相关表。但是，出于某种原因，在tests.py文件中，test_会在名称之前插入：

Traceback (most recent call last):
  File "C:\Users\jont\Documents\application_trackingwc\atp\jobs\tests.py", line 27, in test_empty_sugar_applicants
    number_of_sugar_applicants = Sugar_Applicant.objects.using('sugarcrm').filter(deleted=0).count()

Models.py

class Sugar_Applicant(models.Model):
    id = models.CharField(max_length=36, blank=False, primary_key=True)
    name = models.CharField(max_length=100, blank=True)
    applicant_title = models.CharField(max_length=100, blank=True)
    local_id = models.CharField(max_length=255, blank=True)
    other_title = models.CharField(max_length=255, blank=True)
    dob = models.CharField(max_length=255, blank=True)
    location = models.CharField(max_length=255, blank=True)
    nationality = models.CharField(max_length=255, blank=True)
    other_nationality = models.CharField(max_length=255, blank=True)
    national_insurance_number = models.CharField(max_length=255, blank=True)
    primary_address_street = models.CharField(max_length=150, blank=True)
    primary_address_street_2 = models.CharField(max_length=150, blank=True)
    primary_address_district = models.CharField(max_length=255, blank=True)
    primary_address_city = models.CharField(max_length=100, blank=True)
    primary_address_county = models.CharField(max_length=255, blank=True)
    primary_address_postcode = models.CharField(max_length=20, blank=True)
    telephone = models.CharField(max_length=100, blank=True)
    mobile_phone = models.CharField(max_length=100, blank=True)
    date_modified = models.DateTimeField(default=timezone.now)
    deleted = models.IntegerField(blank=True)
    approved = models.CharField(max_length=255, blank=True)
    job = models.CharField(max_length=50, blank=True)
    location = models.CharField(max_length=50, blank=True)

    class Meta:
        managed = False
        db_table = 'a1234_applicants'

如果我将此代码放在def之外，则可以正常使用，

class TestSugar(TestCase):
    Sugar_Applicant.objects.using('sugarcrm').all().delete();
    number_of_sugar_applicants = Sugar_Applicant.objects.using('sugarcrm').filter(deleted=0).count()
    def test_empty_sugar_applicants(self):
        self.assertEqual(number_of_sugar_applicants, 0)

测试套件可以做一些事情来阻止您对生产数据进行更改......这是一件非常好的事情。

如果要编写使用数据的测试，则需要创建一个fixture。除此之外，拥有固定的测试数据可以让您知道运行的每个测试的正确结果。

从tests.py调用数据库表
