请参考下面有关于打标的代码。
//You can mock concrete classes, not just interfacesLinkedList mockedList = mock(LinkedList.class);//stubbingwhen(mockedList.get(0)).thenReturn("first");when(mockedList.get(1)).thenThrow(new RuntimeException());//following prints "first"System.out.println(mockedList.get(0));//following throws runtime exceptionSystem.out.println(mockedList.get(1));//following prints "null" because get(999) was not stubbedSystem.out.println(mockedList.get(999));//Although it is possible to verify a stubbed invocation, usually it‘s just redundant//If your code cares what get(0) returns, then something else breaks (often even before verify() gets executed).//If your code doesn‘t care what get(0) returns, then it should not be stubbed.verify(mockedList).get(0); |
测试代码请访问 GitHub
请注意,上面的测试代码在运行的时候回出现错误。
这是因为在测试代码运行的时候,我们尝试输出 mockedList.get(1),这个在测试的时候,因为我们打标为抛出异常,所以这一句话将会在测试代码中抛出异常。
运行时候,抛出异常的界面如下:
