在抛出异常之前调用的模拟断言函数

Question

我正在尝试使用Mock对一些代码进行单元测试。我想提出一个异常，并测试异常是否被捕获并在重新引发之前调用另一个函数

except exception as e:
    car.create_log(car_details)
    raise e

单元测试：

car = Car()
car.registrations.update = Mock()
car.registrations.update.side_effect = RegistrationError()
car.create_log = Mock()

car.register_car('123123')

car.create_log.assert_called_once()
self.assertRaises(RegistrationError)

我可以确认该方法引发错误，但是无法在重新引发该错误之前测试方法create_log是否已被调用。

Answer 1

这就是您应该使用- hosts: localhost gather_facts: false tasks: - name: List the file path which doesn't contains the content find: paths: /mrproject/env/ recurse: yes follow: True patterns: config.properties use_regex: True contains: LOG_PATH #contains: ^((?!LOG_PATH).)*$ this Negative lookup doesn't works register: matched_files - name: print matches debug: var: matched_files 的方式：

assertRaises

或者您可以将其传递给callable和arguments：

with self.assertRaises(RegistrationError):
    car.register_car('123123')

car.create_log.assert_called_once()
