我想使用Visual Studio对我的C++项目进行单元测试。将我的项目文件夹添加为测试项目的包含路径后，在尝试编译测试时出现了链接错误：

我的测试源代码：
#include "stdafx.h"
#include "CppUnitTest.h"
#include "Bishop.h"
#include "Board.h"
#include "TestUtils.h"
using namespace Microsoft::VisualStudio::CppUnitTestFramework;
namespace ChessPlusPlusTests
{
TEST_CLASS(BishopTests)
{
public:
TEST_METHOD(ValidMovesTest)
{
// Arrange
Board board{};
Bishop *piece = new Bishop{ Color::WHITE };
Position pos{ 3,3 };
board.placePieceAt(piece, pos);
// Act
auto validPositions = piece->getMovesFor(pos, board);
// Assert
TestUtils::AssertPositions(validPositions, {
0,0,0,0,0,0,0,1,
1,0,0,0,0,0,1,0,
0,1,0,0,0,1,0,0,
0,0,1,0,1,0,0,0,
0,0,0,0,0,0,0,0,
0,0,1,0,1,0,0,0,
0,1,0,0,0,1,0,0,
1,0,0,0,0,0,1,0,
});
}
};
}
如果不添加包含路径，测试项目将无法编译，因为头文件中的包含依赖于主项目中的包含路径。
主项目可以正常编译。
有人能帮我理解出了什么问题吗？
谢谢！
