JMockit与记录的期望不匹配

Question

我能够成功地设置parse（InputStream,DefaultHandler）方法签名的期望，但是当我试图模拟parse（InputSource,DefaultHandler）签名时，JMockit永远看不到调用，并抛出MissingInvocation异常。

下面的示例显示了两个测试用例，一个模拟InputSource风格，一个模拟InputStream风格：

public class SAXTest {

    @Test(expected=RuntimeException.class)
    public void testParseInputSource(@Mocked final SAXParser saxParser) throws Exception {
        new Expectations() {{
            saxParser.parse((InputSource) any, (DefaultHandler) any); result = new RuntimeException("Fail now");
        }};

        SAXParser p = SAXParserFactory.newInstance().newSAXParser();
        InputSource isource = new InputSource(new StringReader("<test/>"));
        p.parse(isource, new DefaultHandler());    
    }

    @Test(expected=RuntimeException.class)
    public void testParseInputStream(@Mocked final SAXParser saxParser) throws Exception {
        new Expectations() {{
            saxParser.parse((InputStream) any, (DefaultHandler) any); result = new RuntimeException("Fail now");
        }};

        SAXParser p = SAXParserFactory.newInstance().newSAXParser();
        InputStream istream = new ByteArrayInputStream("</test>".getBytes());
        p.parse(istream, new DefaultHandler());
    }
}

运行testcase的结果是：

在InputSource测试中使用@capturingannnotation而不是@mockannnotation。
