What is the best way to generate a test report in a file using BOOST.Test?

Question

I know that the report defaults to a standard error, so you need to redirect it to a file. My question is: will we do this inside a global fixture? It doesn't seem to work for me in any way.

This is what I tried -

struct MyConfig
{
 MyConfig()
  : testReport("fileName.log")
  {
    if(!testReport.fail())
     original = std::cerr.rdbuf(testReport.rdbuf());
  }
  ~MyConfig()
    {        
        cerr.rdbuf(original);        
        testReport.close();
    }
    ofstream testReport;
    streambuf* original;

 };

 BOOST_GLOBAL_FIXTURE(MyConfig);

After starting the test, display reports only on the console, although the 0kb file is created with the specified name.

You can try this alternative, adapted from here and the alleged work on Boost 1.34.1. This is similar to what Boost intends - see Using a Results Stream Overloader.

//
// run_tests.cc
//

#define BOOST_AUTO_TEST_MAIN

#include <iostream>
#include <fstream>
#include <cassert>
#include <boost/test/auto_unit_test.hpp>
#include <boost/test/results_reporter.hpp>

std::ofstream ReportRedirector::out;

struct ReportRedirector
{
    ReportRedirector()
    {
        out.open("fileName.log");
        assert( out.is_open() );
        boost::unit_test::results_reporter::set_stream(out);
    }
private:
    static std::ofstream out;
};

BOOST_GLOBAL_FIXTURE(ReportRedirector)

:

You do not need to redirect input yourself if you do not want to. You can also specify the log file through command line arguments:

C:\MyTest.exe --log_sink=fileName.log

It's time to find. Hope this helps!
