我是GTEST / GMOCK测试框架的新手。我正在写一个应用程序 它为我加载了共享对象（运行时为xxx.so） 使用Json::Value 类对象。这是一个开源库。
我想通过模拟加载库函数来测试应用程序 load_mal_lib。我为此编写了Mock类MockLoadLibTask 如上所述。但我面临编译错误。
注意：如果我评论模拟函数load_mal_lib （MOCK_METHOD3（load_mal_lib，SharedLibrary *（string cm_path，string lib_name，Json :: Value＆amp; binaries_info））;）我的测试用例被编译 成功。
