    copied!<p>I have a problem with Mockito.</p> <p>Is it possible to do such a thing:</p> <pre><code>ClassX x = mock(ClassX.class) when(x.methodB()).thenReturn("toto"); String result = x.methodA(); </code></pre> <p>I'm working with Mockito 1.7.</p> <p>I saw there was a "spy" system but they say it's not recommended to use it (why?) on the item we test...</p> <p>I tried that spy function anyway but i get a strange behaviour.</p> <p>Check what i want to do:</p> <p>Real code:</p> <pre><code>String methodA(String arg) { return this.methodB(arg); } String methodB(String arg) { return "toto"; } </code></pre> <p>Test code:</p> <pre><code>@Test public void testTest() { final ClassX x = spy( new ClassX() ); final String argument = "arg"; doReturn("good").when(helper).methodB(argument); assertTrue( x.methodB(argument).equals("good") ); assertTrue( x.methodA(argument).equals("good") ); } </code></pre> <p>As they said i avoided the when thenReturn syntax that could be a problem with a spy (but it doesn't work either anyway)</p> <p>The strange thing is that: assertTrue( x.methodB(argument).equals("good") ); is OK</p> <p>Only the second assertTrue( x.methodA(argument).equals("good") ); is not OK</p> <p>Actually helper.methodA(argument) returns "toto" -> the real result and not the mock result</p> <p>It isn't possible to tell mockito to return "good" in this case??? It seems when the test class call methodB it's ok, but if a method of the spy calls the methodB it doesn't work anymore...</p> <p>I don't know what to do... is it such a strange thing to unit-test 2 methods of the same class and make the tests independent from each others so that a famous mock-test framework doesn't implement this basic function? Isn't it what we just call real unit-testing? Don't understand why they say to avoid using spy method on the tested object...</p> <p>Thanks</p>
