[英]"Any value" for a `const std::string&` argument
I have a function that takes const std::string &
as an argument.我有一个将
const std::string &
作为参数的函数。 I'd like to write something like this:我想写这样的东西:
EXPECT_CALL(mock, convertString(A<std::string>())).Times(0);
This fails compilation:这编译失败:
no known conversion for argument 1 from 'testing::Matcher<std::basic_string<char> >' to 'const testing::Matcher<const std::basic_string<char>&>&'
Am I missing something?我错过了什么吗?
Here is the MCVE, for those inclined to experimment:这是 MCVE,对于那些倾向于实验的人:
#include <string>
#include <gtest/gtest.h>
#include <gmock/gmock.h>
struct ToBeMocked {
virtual ~ToBeMocked() = default;
virtual void callMe(const std::string &arg) = 0;
};
struct Mock : public ToBeMocked {
MOCK_METHOD1(callMe, void (const std::string &arg));
};
TEST(Test, test)
{
Mock mock;
EXPECT_CALL(mock, callMe(::testing::An<std::string>()));
mock.callMe("aaa");
}
PS I am aware of the StrictMock workaround, and will use it. PS 我知道 StrictMock 解决方法,并将使用它。 But...
A<T>()
not working with const ref arguments seems like an oversight...但是......
A<T>()
不使用 const ref 参数似乎是一个疏忽......
The answer turns out to be simple:答案很简单:
EXPECT_CALL(mock, callMe(::testing::An<const std::string &>()));
Use the EXACT type of the function argument, not the value type.使用函数参数的 EXACT 类型,而不是值类型。
