モックに複数のwhenを使用するとどうなりますか？

Question

public class TestClass { 
    @Mock 
    private SomeObject someObject; 

    @InjectMocks 
    private SubjectOfTesting subject; 

    @Before 
    public void setupMock() { 
     when(someObject.doSomething(eq("Meh")).thenReturn("Boing"); 
     when(someObject.doSomething(eq("Foo")).thenReturn("Bar"); 
     when(someObject.doSomething(any()).thenReturn("?!"); // <-- This any() 
    } 

    @Test 
    public void testSomethings() { 
     subject.setArgument("Meh"); 
     String result = subject.useSomeObject(); 
     assertEquals("result is not equal", "Boing", result); 
    } 

    // Multiple tests with other arguments. 
} 

上記のクラスでは、any()と他のクラスを使用できますか？期待どおりに動作しますか？テストで提供する引数に応じて、"Boing"または"Bar"または"?!"を返しますか？ （他が通過する2つの故障、）で

@RunWith(MockitoJUnitRunner.class) 
public class TempTest { 

    @Mock 
    private SomeObject someObject; 

    @InjectMocks 
    private Subject subject = new Subject(); 

    @Before 
    public void setupMock() { 
     when(someObject.doSomething(eq("Meh"))).thenReturn("Boing"); 
     when(someObject.doSomething(eq("Foo"))).thenReturn("Bar"); 
     when(someObject.doSomething(any())).thenReturn("?!"); // <-- This any() 
    } 

    @Test 
    public void testSomethingsMeh() { 
     subject.setArgument("Meh"); 
     String result = subject.useSomeObject(); 
     assertEquals("result is not equal", "Boing", result); 
    } 

    @Test 
    public void testSomethingsFoo() { 
     subject.setArgument("Foo"); 
     String result = subject.useSomeObject(); 
     assertEquals("result is not equal", "Bar", result); 
    } 

    @Test 
    public void testSomethingsAny() { 
     subject.setArgument("Any"); 
     String result = subject.useSomeObject(); 
     assertEquals("result is not equal", "?!", result); 
    } 

    private interface SomeObject { 
     String doSomething(String argument); 
    } 

    private class Subject { 
     private SomeObject someObject; 
     private String argument; 

     public Subject() { 
     } 

     public void setSomeObject(final SomeObject someObject) { 
      this.someObject = someObject; 
     } 

     public String useSomeObject() { 
      return this.someObject.doSomething(this.argument); 
     } 

     public void setArgument(final String argument) { 
      this.argument = argument; 
     } 
    } 
} 

結果：：とそれをテスト

EDIT

org.junit.ComparisonFailure: result is not equal expected:<[Bar]> but was:<[?!]> 
org.junit.ComparisonFailure: result is not equal expected:<[Boing]> but was:<[?!]> 

は、これらのテストに合格させる方法はありますか？

最後のwhenは、すべて透過的です。しかし、スタブの順序を変更すると、必要な結果が得られます。これはあなたが期待するように動作します。

when(someObject.doSomething(any()).thenReturn("?!"); 
when(someObject.doSomething(eq("Meh")).thenReturn("Boing"); 
when(someObject.doSomething(eq("Foo")).thenReturn("Bar");
