在两种情况下,Gmock行为正确w.r.t.应用行为(或不在TC33中)。但是为什么在这两种情况下都会说“无趣的模拟函数调用”?模拟函数调用只有在与EXPECT_CALL
一起指定时才有意思?
使用':: testing :: nice_mock模拟;'为了避免这些警告对于模拟上未明确预期的调用。 –

也许[这将帮助](https://code.google.com/p/googlemock/wiki/FrequentlyAskedQuestions#I_got_a_warning_“Uninteresting_function_call_encountered_-) – 2014-10-02 08:44:33
Doh!我只查了gmock食谱和cheatsheet :( – Bulletmagnet 2014-10-02 08:50:16
