[Test] Where to learn about boost::itest::mock_object?
by Mateusz Loskot 20 Jan '14

20 Jan '14

Hi, I'm looking for a simple mocking library to use together with Boost.Test. There is Turtle (aka Boost.Mock) and googlemock. During retrospection of the big thread on Boost.Test future [1], I found this curious post by Gennadiy [2] about mock_object. I had no idea such facility lives in Boost.Test and it looks it's been there for very long time. I can't find any documentation about mock_oboject, only a couple of examples. So, I have a few questions: Is the mock_object an internal feature or is it dedicated (and ready) to use by Boost.Test users? What are basic features of this mocking facility? How does it compare to Turtle or googlemock?

Does Boost.Test cover 'golden file approach'?
by Journeyer J. Joh 13 Jan '14

13 Jan '14

Hello, I know almost nothing about 'golden file approach'. http://weblogs.java.net/blog/alexeyp/archive/2007/02/testing_command.html >From this blog, you can find the term 'golden file approach'. I want to know if Boost.Test cover this kind of testing. Can I implement 'golden file approach' with Boost.Test? If so please provide me more information about it. Thank you very much. ---------------------------------------- Journeyer J. Joh o o s a p r o g r a m m e r a t g m a i l d o t c o m ----------------------------------------

[Test] using output_test_stream to compare in the middle of a file
by Lloyd 13 Jan '14

13 Jan '14

Hi, We need to test a function which reads a "record" from a binary file. We want to compare the buffer with the "record" in input file.We know the offset of the record in input file. How can we compare the output_test_stream with a certain offset (and length) of the file? or is there any alternative for this? Thanks, Lloyd

Boost.Test segfault clang++3.3 macports cmake
by Dave Gomboc 13 Jan '14

I am getting a segmentation fault when attempting to use Boost.Test. I suspect that I don't have something set up correctly -- your assistance in remedying this would be appreciated. I am using clang++-mp-3.3 as installed by MacPorts on OS X 10.8.4. Here's the crash, which occurs after Boost.Test reports "*** No errors detected".

[boost.test] How to register custom exception for auto test?
by Jörg Becker 13 Jan '14

13 Jan '14

Hi, I'm using the test library of boost 1.49.0 for my unit tests. It works fine so fare, but if my program throws an error, I get the default error message unknown location(0): fatal error in "excption1_test": unknown type, witch hides the original error message. I tried to register an error translator, but without success. Here is what I tried (modified test/test/custom_exception_test.cpp to use auto test with global fixture): #define BOOST_TEST_MODULE "boost test custom_exception_test" #include <boost/test/unit_test.hpp> #include <boost/test/unit_test_monitor.hpp> using namespace boost::unit_test; BOOST_AUTO_TEST_SUITE( custom_exception_testsuite ) struct my_exception1 { explicit my_exception1( int res_code ) : m_res_code( res_code ) {} int m_res_code; }; void throw_my_exception1() { throw my_exception1( 12 ); } void my_exception1_translator( my_exception1 ) { BOOST_TEST_MESSAGE( "Caught my_exception1" ); } class my_config { public: my_config () { unit_test_monitor.register_exception_translator<my_exception1>( &my_exception1_translator ); } }; BOOST_GLOBAL_FIXTURE( my_config ) BOOST_AUTO_TEST_CASE( excption1_test ) { throw_my_exception1(); } BOOST_AUTO_TEST_SUITE_END() Can anybody tell me what I'm missing? Thanks, Jörg

Fwd: support for bjam projects in IDE
by Witold E Wolski 06 Dec '13

06 Dec '13

Hi, I will have to work on bjam based project (rather big). I normally use QT Creator for programming and work with cmake based project. I could't find any hint how to set up an bjam project to work with QT neither information about any IDE which supports bjam. Do boost developer use vim and debug using gdb only? Actually the other guys on the project wrote some python scripts which parse bjam output to generated vcproj files :-@ I would be happy to hear from someone who are happy using bjam with qtcreator or any other IDE for larger projects and how to set this up. All my searches so far regarding bjam return almost exclusively FUD (http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt) but looking at the Jamroot.jam file of the project (more than 1000 lines) I am inclinded to believe it. ;-( -- Witold Eryk Wolski -- Witold Eryk Wolski

Max Boost Fusion tuple parameters
by Rodrigo Madera 15 Sep '13

15 Sep '13

Hello, What is the maximum Boost Fusion tuple param count? I was thinking of using it for about 200-300 elements. Anyone done this? I've heard of defines for this, but never actually *knew* of anyone actually doing it. Thanks, Rodrigo Madera

Too many EOF's using boost::asio
by ustulation 13 Sep '13

13 Sep '13

I have a TCP server and client with following read and write functions: ----------------- Writes ---------------------- void SomeClass::startWrite() { //m_writeBuffer is boost::asio::streambuf..m_writeQueue is std::deque<std::string> m_writeBuffer.sputn(&m_writeQueue.at(0)[0], m_writeQueue.at(0).size()); //m_objStrandWrite is boost::asio::strand boost::asio::async_write( getSocket(), m_writeBuffer, m_objStrandWrite.wrap([this](const boost::system::error_code &e, std::size_t bytesTxd){writeHandler(e, bytesTxd);}) ); } void SomeClass::writeHandler(const boost::system::error_code &refErrorCode, std::size_t bytesTxd) { if(!m_bIsStopped) { m_writeQueue.pop_front(); if(refErrorCode) { if(refErrorCode != boost::asio::error::operation_aborted) { std::cerr << "Write Error: " << refErrorCode.message() << std::endl; stop(); } } else { if(!m_writeQueue.empty()) { startWrite(); } } } } ------------------- Reads ----------------- void SomeClass::startRead() { //m_readBuffer is boost::asio::streambuf..m_objStrandRead is boost::asio::strand boost::asio::async_read_until( getSocket(), m_readBuffer, m_szTermString, m_objStrandRead.wrap([this](const boost::system::error_code &e, std::size_t bytesRxd){readHandler(e, bytesRxd);}) ); } void SomeClass::readHandler(const boost::system::error_code &refErrorCode, std::size_t bytesRxd) { if(!m_bIsStopped) { if(refErrorCode) { if(refErrorCode != boost::asio::error::operation_aborted) { std::cerr << "Read error: " << refErrorCode.message() << std::endl; stop(); } } else { if(bytesRxd) { std::string szRxdData; szRxdData.resize(bytesRxd); m_readBuffer.sgetn(&szRxdData[0], bytesRxd); } startRead(); } } } I get very frequent End Of File (EOF) error on client's read. It is not always but frequent. I am running a threadpool by asking multiple std::threads to execute io_service::run() which never quits until io_service::stop() is called. The data given by the server is almost never more than 5MB. As you see in the code, for any error I call stop() which shuts down the connection gracefully. <Q> *Is there something wrong I'm doing because I see no reason for EOF error. Why should the server close/shutdown the connection?* The code does not do that explicitly. Anyway it is random - out of 10 times maybe 5 are successful reads and 5 become EOF's and I have to restart my client executable to connect again in each of those cases. Other sockets don't do that - eg., I've tested with QTcpSocket of Qt framework and it works all the time (no randomness). -- View this message in context: http://boost.2283326.n4.nabble.com/Too-many-EOF-s-using-boost-asio-tp465117… Sent from the Boost - Users mailing list archive at Nabble.com.

Boost program option parsing issue.
by Vivek Anand 07 Sep '13

07 Sep '13

Hi All, I am using program option for my program. Here is my code snippet string inputFile, outputFile; /* Populate command line arguments */ po::options_description desc("Usage: KDMGenerator [OPTIONS]"); { desc.add_options() ("help", "prints this message") ( "input-file", po::value<string>(&inputFile), "input file name" ) ( "output-file", po::value<string>(&outputFile), "output file name"); } po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc), vm); po::notify(vm); if (vm.count("help") || !vm.size()) { cout <<desc; return 0; } if(vm.count("input-file")) { cout << "Input file :" << inputFile << '\n'; } if(vm.count("output-file")) { cout << outputFile << '\n'; } The issue I am facing is that if i I call my program without passing value for input file, something like ./myapp --input-file --output-file out.txt I get Input file: --output-file i.e the value "--output-file" get stored in inputFile and vm.count("output-file") returns zero. Is this the desired behavior? Is there any workaround for this? -- Vivek,
