Is there a way to use google test on OOP program? - c++

Question

I'm new to google test and currently I'm writing a test for my OOP program, my OOP program is like this:
#include <iostream>
#include <gtest/gtest.h>
using namespace std;
typedef unsigned int NUM;
class Employee
{
protected:
NUM MaSoThue;
private:
NUM Luong;
NUM CMND;
NUM a;
NUM b;
public:
Employee()
{
MaSoThue = 0;
Luong = 0;
CMND = 0;
}
Employee(NUM mst, NUM luong, NUM cmnd)
{
MaSoThue = mst;
Luong = luong;
CMND = cmnd;
}
//get
int getMaSoThue() const { return MaSoThue; }
int getLuong() const { return Luong; }
int getCMND() const {return CMND;}
//set
void setMaSoThue(NUM mst) {if (MaSoThue==0) MaSoThue = mst;}
void setLuong(NUM luong) {Luong = luong;}
void setCMND(NUM cmnd) {if (CMND==0) CMND = cmnd;}
};
int main()
{
// Objects
Employee PhucTri(111,222,333);
Employee MinhDang;
MinhDang.setMaSoThue(1234);
MinhDang.setLuong(2);
MinhDang.setCMND(8888);
//PhucTri
cout <<"MST cua Phuc Tri: "<< PhucTri.getMaSoThue()<<"\n";
cout << "Luong cua Phuc Tri: " << PhucTri.getLuong() << "\n";
cout << "CMND cua Phuc Tri: " << PhucTri.getCMND() << "\n\n";
//MinhDang
cout << "MST cua Minh Dang: " << MinhDang.getMaSoThue() << "\n";
cout << "Luong cua Minh Dang: " << MinhDang.getLuong() << "\n";
cout << "CMND cua Minh Dang: " << MinhDang.getCMND() << "\n";
}
I created a new file, which is below:
#include <gtest/gtest.h>
#include "FileCode.cc"
int main(){}
TEST(No1, PhucTri){
EXPECT_EQ(PhucTri.getMaSoThue(),111);
}
The compiler says that the object "PhucTri" isn't declared in this scope, but I did create it in my first file, is there any way I can get it right on the object ?

Answer 1

In general, Try to not include .cpp files, declare your class and its methods inside a .h file, define methods in .cpp and then create a test file that includes your header.
You have two options here, either define a test class that has an instance of your class follows instructions here.
Or do something like this :
#include <gtest/gtest.h>
#include "FileCode.h"
TEST(No1, PhucTri)
{
Employee PhucTri(111,222,333);
// initialize your data
// ......
EXPECT_EQ(PhucTri.getMaSoThue(),111);
}
