测试异常时如何验证方法是否被调用

Question

考虑以下代码：

@Rule ExpectedException expected = ExpectedException.none();
@Mock private MyObject mockMyObject;
private Converter converter; // Object under test

@Before public void before() {
    MockitoAnnotations.initMocks(this);
    when(mockMyObject.doSomething1()).thenReturn(1);
    when(mockMyObject.doSomething2()).thenReturn("2");
}

@After public void after() {
    verifyNoMoreInteractions(mockMyObject); // Exception test fails here
}

@Test public void testConverter() {
    assertThat(converter.convert(mockMyObject), notNullValue());
    verify(mockMyObject).doSomething1();
    verify(mockMyObject).doSomething2();
}

@Test public void testConverterException() {
    when(mockMyObject.doSomething1()).thenThrow(MyException.class);
    expected.expect(MyException.class);
    converter.convert(mockMyObject);
    verify(mockMyObject).doSomething1(); // Never gets called
}

我希望能够做的是，在异常测试中，标记我希望调用 doSomething1()。但是，异常会在 converter.convert() 处抛出，这意味着永远不会调用 verify() 调用。因此 verifyNoMoreInteractions() 在 after() 中失败。

注意：这是一个非常通用的示例，用于隐藏我们的任何内部代码。

好的，笨蛋。我发现与此类似的问题已经存在，简单的答案是：

@Test public void testConverterException() {
    when(mockMyObject.doSomething1()).thenThrow(MyException.class);
    expected.expect(MyException.class);
    try {
        converter.convert(mockMyObject);
    } finally {
        verify(mockMyObject).doSomething1(); // Now it gets called
    }
}
