org.mockito.exceptions.misusing.UnfinishedStubbingException: Unfinished stubbing detected here: -> at com.linkedin.venice.controller.TestVeniceParentHelixAdminWithAcl.testUpdateAndGetAndDeleteAcl(TestVeniceParentHelixAdminWithAcl.java:144) 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 final method, which is not supported 3. you are stubbing the behaviour of another mock inside before 'thenReturn' instruction is completed

org.mockito.exceptions.misusing.CannotStubVoidMethodWithReturnValue: 'stop' is a *void method* and it *cannot* be stubbed with a *return value*! Voids are usually stubbed with Throwables: doThrow(exception).when(mock).someVoidMethod(); If you need to set the void method to do nothing you can use: doNothing().when(mock).someVoidMethod(); For more information, check out the javadocs for Mockito.doNothing(). *** If you're unsure why you're getting above error read on. Due to the nature of the syntax above problem might occur because: 1. The method you are trying to stub is *overloaded*. Make sure you are calling the right overloaded version. 2. Somewhere in your test you are stubbing *final methods*. Sorry, Mockito does not verify/stub final methods. 3. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies - - with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method. 4. Mocking methods declared on non-public parent classes is not supported.

org.mockito.exceptions.misusing.WrongTypeOfReturnValue: ZKStore cannot be returned by getClustersLeaderOf() getClustersLeaderOf() should return List *** If you're unsure why you're getting above error read on. Due to the nature of the syntax above problem might occur because: 1. This exception *might* occur in wrongly written multi-threaded tests. Please refer to Mockito FAQ on limitations of concurrency testing. 2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies - - with doReturn|Throw() family of methods.
