在Django中,我想使用Unit Test来测试MS-SQL Server遗留数据库。数据库正在使用存储过程来添加数据。情况如下:
MS-SQL数据库在Django中具有以下设置:
DATABASES['vadain_import'] = {
'ENGINE': 'sql_server.pyodbc',
'USER': 'xx',
'PASSWORD': 'xxx',
'HOST': '192.168.103.102',
'PORT': '',
'NAME': 'Vadain_import',
'OPTIONS': {
'driver': 'SQL Server Native Client 11.0',
'MARS_Connection': True,
}
}
数据库的模型使用inspectdb,例如:
class WaOrders(models.Model):
order_id = models.IntegerField(primary_key=True, db_column='intOrderId')
type = models.TextField(db_column='chvType', blank=True)
class Meta:
db_table = 'WA_ORDERS'
database_name = 'vadain_import'
managed = False
# (There's a lot more of properties and models)
在模型中正在执行存储过程。我不能使用保存 Django的功能,如WAOrders.save(),因为在MS-SQL中 数据库主键是在存储过程中生成的。
@classmethod
def export(cls, **kwargs):
# Stored procedure for adding data into the db
sql = "declare @id int \
set @id=0\
declare @error varchar(1000)\
set @error=''\
exec UspWA_OrderImport\
@intOrderId=@id out\
,@chvType=N'%s'" % kwargs['type'] + " \
,@chvErrorMsg=@error output\
select @id as id, @error as 'error' \
"
# Connection Vadain db
cursor = connections['vadain_import'].cursor()
# Execute sql stored procedure, no_count is needed otherwise it's returning an error
# Return value primary key of WAOrders
try:
cursor.execute(no_count + sql)
result = cursor.fetchone()
# Check if primary key is set and if there are no errors:
if result[0] > 1 and result[1] == '':
# Commit SP
cursor.execute('COMMIT')
return result[0]
有一个用于创建模型的映射,因为MS-SQL 数据库期望不同的数据然后是正常的对象,比如'order'。
def adding_data_into_vadain(self, order):
for curtain in order.curtains.all():
order_id = WaOrders.export(
type=format(curtain.type)
)
# relation with default and vadain db.
order.exported_id = order_id
order.save()
该功能通过运行程序正常工作,但通过运行'manage.py test'将创建一个测试数据库。这给出了以下问题:
我的测试如下:
class AddDataServiceTest(TestCase):
fixtures = ['order']
def test_data_service(self):
# add data into vadain_import data
for order in Order.objects.all():
AddingDataService.adding_data_into_vadain(order)
# test the exported values
for order in Order.objects.all():
exported_order = WaOrders.objects.get(order_exported_id=order.exported_id)
self.assertEqual(exported_order.type, 'Pleat curtain')
有人可以告诉我如何测试这种情况吗?
答案 0 :(得分:0)
也许在你的WaOrders里面你可以扩展save()方法并调用那里的导出函数。
