我是 Visual Studio 2017 上 Boost.Test 的新手。

我正在尝试使用以下测试来测试一种方法：

#define BOOST_TEST_MODULE astroTimeTests
#include <boost/test/included/unit_test.hpp>
#include <ctime>
#include "../../AstroTime/Convert.h"

struct TestFixture
{
    Convert convert_instance;

    TestFixture()
        : convert_instance()
    {}

    ~TestFixture() = default;
};

BOOST_FIXTURE_TEST_SUITE(TestConvert, TestFixture)

BOOST_AUTO_TEST_CASE(julianToGreenWichCase)
{
    // http://www.onlineconversion.com/julian_date.htm
    tm day1 = { 12, 28, 16, 2, 10, 119, 0, 0, 0};
    BOOST_REQUIRE_EQUAL(day1, convert_instance.JulianToGreenWich(2458790.18625f));
}

BOOST_AUTO_TEST_SUITE_END()

JulianToGreenWich从 .返回一个tm结构ctime。

但是我做错了，因为我收到以下错误：

错误 C2678 二进制“==”：未找到采用“const Left”类型的左侧操作数的运算符（或没有可接受的转换）

错误 C2338 类型必须实现 operator<< 才能打印

错误 C2679 二进制“<<”：未找到采用“const T”类型右侧操作数的运算符（或没有可接受的转换）

如何测试两个值day1和结果JulianToGreenWich是否相等？

这就是我修复此错误的方法：

#define BOOST_TEST_MODULE astroTimeTests
#include <boost/test/included/unit_test.hpp>
#include <ctime>
#include <iostream>

#include "../../AstroTime/Convert.h"

struct TestFixture
{
    Convert convert_instance;

    TestFixture()
        : convert_instance()
    {}

    ~TestFixture() = default;
};

bool operator ==(tm const &left, tm const &right)
{
    return(
           left.tm_sec == right.tm_sec
        && left.tm_min == right.tm_min
        && left.tm_hour == right.tm_hour
        && left.tm_mday == right.tm_mday
        && left.tm_mon == right.tm_mon
        && left.tm_year == right.tm_year);
}

std::ostream& operator<<(std::ostream& os, const tm& dt)
{
    os << dt.tm_hour << " " << dt.tm_min << " " << dt.tm_sec << ", "
       << dt.tm_mday << " " << dt.tm_mon << " " << (1900 + dt.tm_year) << std::endl;

    return os;
}

BOOST_FIXTURE_TEST_SUITE(TestConvert, TestFixture)

BOOST_AUTO_TEST_CASE(julianToGreenWichCase)
{
    // http://www.onlineconversion.com/julian_date.htm
    tm day1 = { 12, 28, 16, 2, 10, 119, 0, 0, 0};
    BOOST_REQUIRE_EQUAL(day1, convert_instance.JulianToGreenWich(2458790.18625f));
}

BOOST_AUTO_TEST_SUITE_END()
