存根不会让你考试不及格，mock可以。

以下是我的理解……

如果您在本地创建测试对象并将其提供给本地服务，则使用的是模拟对象。 这将为您在本地服务中实现的方法提供测试。 它用于验证行为 当您从真正的服务提供者获得测试数据时(尽管是从接口的测试版本获得对象的测试版本)，您是在使用存根 存根可以有逻辑来接受特定的输入并给出相应的输出来帮助您执行状态验证…

存根是一个简单的伪对象。它只是确保测试顺利进行。 mock是更聪明的存根。您验证您的测试通过了它。

Stubs vs. Mocks Stubs provide specific answers to methods calls ex: myStubbedService.getValues() just return a String needed by the code under test used by code under test to isolate it cannot fail test ex: myStubbedService.getValues() just returns the stubbed value often implement abstract methods Mocks "superset" of stubs; can assert that certain methods are called ex: verify that myMockedService.getValues() is called only once used to test behaviour of code under test can fail test ex: verify that myMockedService.getValues() was called once; verification fails, because myMockedService.getValues() was not called by my tested code often mocks interfaces

测试双打:

Fake: Fakes are objects that have working implementations, but not the same as production one. Such as: in-memory implementation of Data Access Object or Repository. Stub: Stub is an object that holds predefined data and uses it to answer calls during tests. Such as: an object that needs to grab some data from the database to respond to a method call. Mocks: Mocks are objects that register calls they receive. In test assertion, we can verify on Mocks that all expected actions were performed. Such as: a functionality that calls e-mail sending service. for more just check this.
