You will find a Works class and a DoesNotWork class. Both are essentially the same with a small difference being the DoesNotWork class does fail and extends and empty class. DoesNotWork.java: @ExtendWith({MockitoExtension.class}) public class DoesNotWork extends ToBeExtended{ @Mock ToBeMocke...
a class using generics in a particular way Mockito will throw an exception when attempting to mock the class. This only occurs if the class under test uses method reference to refer to a private method; calling the same method using regular lambda syntax will allow the creation of the mock...
通过代码可以看出Jerry是一个mock对象, goHome()和doSomeThingB()是使用了实际调用技术,而doSomeThingA()被mockito执行了默认的answer行为(这里是个void方法,so,什么也不干)。 总结: spy和callrealmethod都可以实现部分mock,唯一不同的是通过spy做的桩实现仍然会调用实际方法(我都怀疑这是不是作者的bug)。 ★ 批...

(IllegalStateException.class)81 .when(mock)82 .simpleMethod(1);83 // then on lenient stubbing, we can call it with different argument with no exception:84 mock.simpleMethod(200);85 // and stubbing works, too:86 assertThatThrownBy(87 new ThrowableAssert.ThrowingCallable() {88 public void...
stub the same method more than once, to change the behaviour of a mock in the middle of a test. 主要针对上面三种场景,when无法解决的情况,对于第三点,说明如下:可以看到如果使用when形式的Stub,相关的mock副作用会显现 //mock creationList<String> mockedList = mock(List.class); ...
When a method under test, involves using a static method from the same class (or from a different class), we will need to include that class in prepareForTest annotation before the Test (or on the test class). Important points to Mock Static Methods: ...
LinkedList mockedList = mock(LinkedList.class); 1.4 设置对象调用的预期返回值 通过when(mock.someMethod()).thenReturn(value) 来设定 Mock 对象某个方法调用时的返回值。我们可以看看源码中关于thenReturn方法的注释: 使用when(mock.someMethod()).thenThrow(new RuntimeException) 的方式来设定当调用某个方法时抛出...
If we do not usetry-with-resourcesblock, as suggested, the mocking/stubbing/verifying will work as expected but leaves the class in a mocked state. 3. Mocking No-Args Static Methods Let us mock the first methodgetVal()that takes no arguments and returns a String value"foo". We are mock...
一般模拟bean使用的是thenreturn方法,但对于如果mock的方法修改了入参时,可以使用thenAnswer方法。 比如mock对象B的methodZ(Object obj)方法时,如果methodZ方法里修改了obj的属性attrName时,我们通过mock可以写成: @Autowired B b; when(b.mothodZ(obj)).thenAnswer(e->{ ...
