C++(14)-谷歌测试未定义的标识符

Question

我使用的是c++14为什么谷歌测试无法获取curl_client类对象指针我在CurlClientTest中正确初始化了它吗？

测试代码：

#include "../src/include/CurlClient.h"
#include <gtest/gtest.h>
#include <string>
class CurlClientTest : testing::Test {
public:
SimpleCURLClient::CurlClient *curl_client;
virtual void SetUp() {
curl_client = new SimpleCURLClient::CurlClient(test_url);
}
virtual void TearDown() {
delete curl_client;
}
private:
std::string test_url = "http://postman-echo.com/get?foo1=bar1&foo2=bar2";
};
TEST(CurlClientTest, CurlClientInitTest) {
std::cout << curl_client->getCurlUrl << "n";
}

CurlClient.h:的代码

#include <curl/curl.h>
#include <exception>
#include <iostream>
#include <sstream>
#include <string>
#include <utility>
#include <vector>
#ifndef UTILS_CURLCLIENT_H
#define UTILS_CURLCLIENT_H
namespace SimpleCURLClient {
class CurlClient {
public:
CurlClient(std::string remote_url, int ip_protocol = 1, int timeout = 10,
bool follow_redirects = 1);
~CurlClient();
void setCurlUrl(std::string &new_url);
std::string getCurlUrl();
void setOption(CURLoption curl_option_command, long curl_option_value);
void setOption(CURLoption curl_option_command, std::string curl_option_value);
void setHeader(std::vector<std::string> &header_list);
std::pair<CURLcode, std::string> makeRequest();
std::pair<CURLcode, std::string> makeRequest(std::string &post_params);
std::pair<CURLcode, std::string> sendGETRequest();
std::pair<CURLcode, std::string> sendPOSTRequest(std::string &post_params);
std::pair<CURLcode, std::string> sendDELETERequest(std::string &post_params);
private:
std::string m_curl_url;
CURL *m_curl;
struct curl_slist *m_curl_header_list;
};
} // namespace SimpleCURLClient
#endif // UTILS_CURLCLIENT_H

错误：

答案(Chris Olsen在评论中给出(：

我们必须使用TEST_F而不是TEST。同时将CurlClientTest更改为public。下面的测试代码有效。

#include "../src/include/CurlClient.h"
#include <gtest/gtest.h>
#include <string>
class CurlClientTest : public testing::Test {
public:
SimpleCURLClient::CurlClient *curl_client;
virtual void SetUp() {
curl_client = new SimpleCURLClient::CurlClient(test_url);
}
virtual void TearDown() {
delete curl_client;
}
private:
std::string test_url = "http://postman-echo.com/get?foo1=bar1&foo2=bar2";
};
TEST_F(CurlClientTest, CurlClientInitTest) {
std::cout << curl_client->getCurlUrl() << "n";
}

使用fixture的测试需要使用TEST_F宏。有关更多信息，请参阅谷歌测试入门中的测试夹具。

TEST_F(CurlClientTest, CurlClientInitTest) {
std::cout << curl_client->getCurlUrl << "n";
}
