即使测试通过而且不确定原因,我总是会收到错误.这次我检查如果视图为空则有一个空指针.
@Before
public void setUp() {
MockitoAnnotations.initMocks(this);
mockView = mock(CollectionContract.View.class);
// Get a reference to the class under test
presenter = new CollectionPresenter(repository, mockView);
}
@Test(expected = NullPointerException.class)
public void testShowingUIWhenViewIsNull() {
presenter = new CollectionPresenter(repository, null);
verify(mockView).showAddCollection();
}
这是堆栈跟踪:

如果视图存在,为什么sql异常会出现在show view ui上？坚持这一点,因为我几乎在每次测试中都能找到它.任何想法都会很棒.谢谢.
