gmock-如何使用noexcept说明符模拟函数 [英] gmock - how to mock function with noexcept specifier

问题描述

我需要模拟以下功能:

 virtual void fun() noexcept = 0;

是否可以使用gmock?

Is it possible using gmock ?

Gmock具有以下宏:#define GMOCK_METHOD0_(tn, constness, ct, Method, ...)，但有一条注释:// INTERNAL IMPLEMENTATION - DON'T USE IN USER CODE!!!而且我不知道如何使用该宏(参数tn和ct表示什么)?

Gmock has the following macro:#define GMOCK_METHOD0_(tn, constness, ct, Method, ...) but there is a comment: // INTERNAL IMPLEMENTATION - DON'T USE IN USER CODE!!! Moreover I don't know how to use that macro (what the parameters tn and ct means) ?

修改

以下模拟:

GMOCK_METHOD0_(, noexcept, ,fun, void());

使用gmock 1.7.0进行编译，但是当我使用gmock 1.8.1进行编译时，出现编译错误:

compiles with gmock 1.7.0 but when I compile it using gmock 1.8.1 I get the compilation errors:

main.cpp:17: error: expected identifier before ‘noexcept’
 GMOCK_METHOD0_(, noexcept, ,fun, void());
                  ^

推荐答案

现在，从v1.10.0开始，使用新语法就可以做到这一点. 请参见更改日志和

Now this is possible since v1.10.0 with the new syntax. see change log and new syntax explanation

新语法包含一个单独的参数规范以传递限定符

The new syntax contains a separate argument specs to pass the qualifiers

class MyMock {
   public:
      MOCK_METHOD(ReturnType, MethodName, (Args...), (Specs...));
};
