Describe the bug

There are no test cases in the executable compiled by this test framework. Even if the main function that runs all the tests is included, it still does not work. Like as And after my own troubleshooting, I found that the problem was in a class : simplelogger. If I don't use this class in the test source file, everything will work properly. Once I call it, the above problem will occur. Moreover, after my own test, if simpleLogger is called in the normal executable program, it will run normally.

Steps to reproduce the bug

The detailed code is as follows:

/// include/simpleLogger.h
#pragma once
#include <fmt/format.h>
#include <fstream>
#include <iostream>
#include <string>

using std::string;

enum LEVEL
{
    DEBUG,
    INFO,
    ERROR
};

class SimpleLogger
{
  private:
    std::fstream file;

    void writeLog(LEVEL level, string msg)
    {
        string levelStr;
        switch (level)
        {
        case DEBUG:
            levelStr = "Debug";
            break;
        case ERROR:
            levelStr = "Error";
            break;
        case INFO:
        default:
            levelStr = "Info";
        }

        auto s = fmt::format("[{}] {}\n", levelStr, msg);

        // string s = "[" + levelStr + "]" + "\r" + msg;

        std::cout << s << "\n";

        file.write(s.c_str(), s.length());
        file.flush();
    }

  public:
    SimpleLogger(string filename) : file(filename, std::ios::out) { }

    ~SimpleLogger() 
    {
        if (file.is_open())
        {
        file.close();
        }
    }

    void Debug(string msg)
    {
        writeLog(LEVEL::DEBUG, msg);
    }

    void Info(string msg)
    {
        writeLog(LEVEL::INFO, msg);
    }

    void Error(string msg)
    {
        writeLog(LEVEL::ERROR, msg);
    }
};

// simpleLogger_test.cpp
#include "SimpleLogger.h"
#include <fstream>
#include <gtest/gtest.h>
#include <string>

 TEST(Logger, writeByLogger)
 {
     SimpleLogger s("./test.txt");
     s.Debug("Hello world!");
 }
