在Mockito中打桩(即stub)有两种方法when(...).thenReturn(...)和doReturn(...).when(...)。这两个方法在大部分情况下都是可以相互替换的,但是在使用了Spies对象(@Spy注解),而不是mock对象(@Mock注解)的情况下他们调用的结果是不相同的(目前我只知道这一种情况,可能还有别的情形下是不能相互替换的)。 ●...
代码语言:javascript 复制 <replaceConfiguration name="when" text="when($mock$.$MethodCall$($Parameter$)).thenReturn($result$)" recursive="false" caseInsensitive="false" type="JAVA" pattern_context="default" reformatAccordingToStyle="false" shortenFQN="false" replacement="doReturn($result$).when(...
Mockito.doReturn(100).when(spyList).size(); assertEquals(100, spyList.size()); } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 注: 在监控对象上使用when(Object)来进行打桩有时候是不可能或者不切实际的。 在使用spy的时候,推荐用doReturn|Answer|Throw()等一系列的方法来打桩。 List list = new Lin...
当调用when(spy.get(0)).thenReturn("foo")时,会调用真实对象的get(0),由于list是空的所以会抛出IndexOutOfBoundsException异常,用doReturn可以避免这种情况的发生,因为它不会去调用get(0)方法。 9.使用ArgumentCaptor(参数捕获器) 捕获方法参数进行验证
doReturn("World").when(myMock); doSomeTestingStuff(); // ERROR 3 is never reported, because there are no more Mockito calls. } Now when I first wrote this answer more than five years ago, I wrote So I would recommend the use of the MockitoJUnitRunner wherever possible. However, a...

NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz) will actually call foo.bar(null), which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any()) ...
foo(1)).thenReturn(1); Mockito.lenient().doReturn(1).when(mock).foo(1); } Details: Why 2 new public methods? Sometimes common stubbing has a form of one or few stubbings in "before" method - it's best to configure leniency per stubbing. Sometimes a mock object has many common ...
所以这完全是关于你希望你的语句如何显示以及你的代码风格是关于什么的。doReturn和thenReturn或多或少是...
