Mockito - what does verify method do?
13,190
Solution 1
Mockito.verify(MockedObject).someMethodOnTheObject(someParametersToTheMethod);
verifies that the methods you called on your mocked object are indeed called. If they weren't called, or called with the wrong parameters, or called the wrong number of times, they would fail your test.
Solution 2
It asserts that the method was called, and with those arguments.
Comment out:
//mockedList.add("one");
Or change its argument and the test will fail.

Let's say i have the following psuedo like test code:
//Let's import Mockito statically so that the code looks clearer import static org.mockito.Mockito.*; //mock creation List mockedList = mock(List.class); //using mock object mockedList.add("one"); mockedList.clear(); //what do these two verify methods do ? verify(mockedList).add("one"); verify(mockedList).clear();
I keep showing the test passed but i dont know what the verify means ? what is it verifying exactly ? I understand that i mocked a call to add and clear but what does the two verify calls do ?
