Django 在夹具拆卸中测试 IntegrityError

Python
from Django.test import TestCase
from Django.db import IntegrityError
from myapp.models import MyModel
class MyModelTestCase(TestCase):
    fixtures = ['testdata.JSon']
    def test_integrity_error(self):
        # 加载夹具数据
        self.assertGreater(len(self.fixtures), 0)
        # 执行数据库操作
        try:
            # 创建一个违反完整性约束的对象
            MyModel.objects.create(field1='value1', field2='value2')
        except IntegrityError:
            # 捕获IntegrityError异常
            pass
        else:
            # 如果没有捕获到异常，则测试失败
            self.fAIl('IntegrityError not rAIsed')
