I am new to unit testing, and I continously hear the words ‘mock objects’ thrown around a lot. In layman’s terms, can someone explain what mock objects are, and what they are typically used for when writing unit tests? 11 Answers 11
I like to simulate an asynchronous web service call in my Dart application for testing. To simulate the randomness of these mock calls responding (possibly out of order) I’d like to program my mocks to wait (sleep) for a certain period of time before returning the ‘Future’. How can I do this? 8 Answers 8

I am getting following exception while running the tests. I am using Mockito for mocking. The hints mentioned by Mockito library are not helping. org.mockito.exceptions.misusing.UnfinishedStubbingException: Unfinished stubbing detected here: -> at com.a.b.DomainTestFactory.myTest(DomainTestFactory.java:355) E.g. thenReturn() may be missing. Examples of correct stubbing: when(mock.isOk()).thenReturn(true); when(mock.isOk()).thenThrow(exception); doThrow(exception).when(mock).someVoidMethod(); Hints: 1. missing thenReturn() 2. you are trying to stub a … Read more

We have been using Mock for python for a while. Now, we have a situation in which we want to mock a function def foo(self, my_param): #do something here, assign something to my_result return my_result Normally, the way to mock this would be (assuming foo being part of an object) self.foo = MagicMock(return_value=”mocked!”) Even, if … Read more

I’d like to test an abstract class. Sure, I can manually write a mock that inherits from the class. Can I do this using a mocking framework (I’m using Mockito) instead of hand-crafting my mock? How? 12 Answers 12
