找不到 gmock ElementsAreArray() 函数

Question

我正在尝试在另一个函数中调用函数 ElementsAreArray()。我通常在我的测试中使用它，但我想让测试报告更好，并将其组织在一个函数上。所以我创建了以下文件：

gUnitTest_Test_Array.cpp 我有我的函数定义：

#include "gUnitTest_Test_Array.h"

void gtest_array::expect_that_size1(volatile signed long arrayA[CIC8_TABLE_SIZE],volatile signed long arrayB[CIC8_TABLE_SIZE], std::string msg1, std::string msg2)
{
    using namespace testing;

            bool HasError = false; 
            EXPECT_THAT(arrayA, ElementsAreArray(arrayB)) << (HasError = true);

            if (HasError)
                std::cout << msg1; 
            else 
                std::cout << msg2;
}

gUnitTest_Test_Array.h 我有我的 class 声明：

#pragma once
#ifndef GUNITTEST_TEST_ARRAY_H
#define GUNITTEST_TEST_ARRAY_H
#include "gUnitTest_Common_Defs.h"


using namespace std;

class gtest_array
{
public:
    void expect_that_size1(volatile signed long arrayA[CIC8_TABLE_SIZE], volatile signed long arrayB[CIC8_TABLE_SIZE], std::string msg1, std::string msg2);
};


#endif

gUnitTest_Common_Defs.h 其中包含必要的库和定义

#pragma once
//#ifndef GUNITTEST_COMMON_DEFS_H
//#define   GUNITTEST_COMMON_DEFS_H
#include <stdio.h>
#include <string>
#include <gtest/gtest.h>
#include <gmock/gmock.h> 

#define ... //Whatever I need to define

然后在我的测试文件中调用函数：

std::string msg1 = "failed";
std::string msg2 = "passed";
TestArray1.expect_that_size1(sG_Demodulation_Diagnostics_Buffers.WNLCPF_CIC8_Decim, s32L_CIC8_table, msg1, msg2);

问题是当我尝试编译时，编译器抱怨它没有找到函数 ElemetsAreArray()。这对我来说没有意义，因为我包含了所有必要的 gtest headers 并且在移动到函数之前，我在我的测试中内联使用了这个函数，如下所示：

EXPECT_THAT(sG_Demodulation_Diagnostics_Buffers.WNLCPF_CIC8_Decim, ElementsAreArray(s32L_CIC8_table)) << "The CIC8 block test failed. Failed at index: " << i;

这是错误信息

上面关于 arrayA 和 arrayB 本身不是数组的评论是正确的。我知道，但我认为 ElementsAreArray() 会很高兴从指针接收地址。结果，正如上面所评论的那样，它将它转换为 std::vectors，所以我找到的解决方法是在函数内部创建我的向量的本地副本（如果有人有任何更有效的想法，请告诉我):

#pragma once
//#ifndef GUNITTEST_TEST_ARRAY_H
//#define   GUNITTEST_TEST_ARRAY_H
#include "gUnitTest_Common_Defs.h"


using namespace std;

class gtest_array
{
public:
    void expect_that_size1(volatile signed long (*arrayA), volatile signed long (*arrayB), uint16_t table_size, std::string msg1, std::string msg2);
};


//#endif

#include "gUnitTest_Test_Array.h"

void gtest_array::expect_that_size1(volatile signed long (*arrayA),volatile signed long (*arrayB), uint16_t table_size, std::string msg1, std::string msg2)
{
    using namespace testing;
    signed long array1[CIC8_TABLE_SIZE];
    signed long array2[CIC8_TABLE_SIZE];

    std::copy(arrayA, arrayA + table_size, array1);
    std::copy(arrayB, arrayB + table_size, array2);

    bool HasError = false; 
    EXPECT_THAT(array1, ElementsAreArray(array2)) << (HasError = true);

    if (HasError)
        std::cout << msg1; 
    else 
        std::cout << msg2;
}
