使用BOOST.Test在文件中生成测试报告的更好方法是什么？ [英] What is the better way to generate test report in a file using BOOST.Test?

问题描述

我知道默认报告是针对标准错误，因此必须重定向到一个文件。
我的问题是我们在一个全局夹具里这样做吗？

I know by default report is directed to standard-error, and so one has to redirect it to a file. My question is shall we do this inside a global fixture? Which isn't seem to be working for me some how.

这是我试过的 -

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);

运行测试后，仅在控制台上报告输出，但使用给定名称创建一个0kb文件。

After running the test, report outputs on console only, though a 0kb file is created with the given name.

推荐答案

您可以尝试此替代方案，修改自这里，并声称工作在Boost 1.34.1。这似乎更像Boost意图 - 查看结果流的使用overrider。

You could try this alternative, adapted from here and alleged to work on Boost 1.34.1. This seems to be more as Boost intends - see the usage of a results stream overrider.

//
// 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)
