用法: assert_not_called()断言模拟从未被调用过。>>> m = Mock() >>> m.hello.assert_not_called() >>> obj = m.hello() >>> m.hello.assert_not_called() Traceback (most recent call last): ... AssertionError: Expected 'hello' to not have been called. Called 1 times....
# 需要导入模块: from mock import MagicMock [as 别名]# 或者: from mock.MagicMock importassert_not_called[as 别名]deftest_missing_collection_harvest(self, mock_rabbit_worker_class):mock_rabbit_worker = MagicMock(spec=RabbitWorker) mock_rabbit_worker_class.side_effect = [mock_rabbit_worker]# Err...
期望的调用未发生:Mock对象的assert_*方法是基于期望的调用进行断言的。如果在代码执行过程中,并没有实际调用Mock对象,那么断言将会失败。在这种情况下,可以使用Mock.assert_not_called()方法来验证函数未被调用。 调用参数不匹配:Mock对象的assert_*方法也会验证调用时传递的参数是否与期望的一致。如果调用的参...
| assertNotEquals = assertNotEqual(self, first, second, msg=None) | | assertNotIn(self, member, container, msg=None) | Just like self.assertTrue(a not in b), but with a nicer default message. | | assertNotIsInstance(self, obj, cls, msg=None) | Included for symmetry with assertIsI...
assertIsNotNone(x,[msg='测试失败时打印的信息']): 断言x是否None,不是None则测试用例通过。assertIn(a,b,[msg='测试失败时打印的信息']): 断言a是否在b中,在b中则测试用例通过。assertNotIn(a,b,[msg='测试失败时打印的信息']): 断言a是否在b中,不在b中则测试用例通过。assertIsInstance(a,b,[...
Python程序运行时有个特殊的只读属性__debug__,源码解释运行(包括使用import导入模块)时值为True,这时assert语句起作用,确实可以在特定条件不满足时阻止执行后面的代码。但是,把Python程序源码使用优化模式编译为字节码后运行时,__debug__的值为False,并且在优化编译时会删除所有的assert语句,再也起不到任何的约束和拦...
Assert in Python: Example Here’s an example to demonstrate the usage of assert in Python: defcalculate_average(numbers):assertlen(numbers)>0,"List must not be empty"total=sum(numbers)average=total/len(numbers)returnaveragedata=[5,10,15,20]result=calculate_average(data) ...
Python: assert不打印错误消息 Python中的assert语句用于在代码中检查条件是否为真。如果条件为假,则会引发AssertionError异常,并且可以选择性地提供错误消息。 assert语句的语法如下: 代码语言:txt 复制 assert condition, message 其中,condition是要检查的条件,如果为False,则会引发异常。message是可选的错误消息,用于...
2.assertNotEqual(self, first, second, msg=None) --判断两个参数不相等:first != second 3.assertIn(self, member, container, msg=None) --判断是字符串是否包含:member in container 4.assertNotIn(self, member, container, msg=None) --判断是字符串是否不包含:member not in container ...
3. How to Handle Assertion Errors in Python? To ensure that assumptions hold true, we rely on assertion statements. These assertions are our way of stating, “I believe this condition should be true at this point in the code.” But what happens when these assumptions are not met? This is...
