Question for Boost.Threads and Boost.Test
by young 19 Jan '14

19 Jan '14

According to Boost document, Boost.Test can only be statically linked. Boost.Threads can only be dynamically linked. Then what boost_unit_test_framework-vc100-mt-1_53.lib for? Is it for dynamically linked dll? what libboost_thread-vc100-mt-1_53.lib for? Is it for static library? -- View this message in context: http://boost.2283326.n4.nabble.com/Question-for-Boost-Threads-and-Boost-Tes… Sent from the Boost - Users mailing list archive at Nabble.com.

[Test] Where to learn about boost::itest::mock_object?
by Mateusz Loskot 19 Jan '14

19 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 12 Jan '14

12 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 12 Jan '14

12 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". Program received signal EXC_BAD_ACCESS, Could not access memory.

[boost.test] How to register custom exception for auto test?
by Jörg Becker 12 Jan '14

12 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

[BOOST]BOOST_AUTO_TEST_CASE_TEMPLATE vs BOOST_AUTO_TEST_CASE
by Hemanth Choudary M V (RBEI/ETA1) 12 Jan '14

12 Jan '14

Hi, Scenario1: Both files are present in the same Project BoostUnitTest. fileA: typedef boost::mpl::list<long long,unsigned char> test_types; BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types ) { BOOST_CHECK_EQUAL( sizeof(T), (unsigned)4 ); } BOOST_AUTO_TEST_SUITE_END() fileB: typedef boost::mpl::list<long long,unsigned char> test_types; BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types ) { BOOST_CHECK_EQUAL( sizeof(T), (unsigned)4 ); } BOOST_AUTO_TEST_SUITE_END() As shown above, MySuite is extended across 2 files fileA and fileB. The BOOST_AUTO_TEST_CASE_TEMPLATE name is same across the both the files and and the suite name is also same across both the files.. Boost is able to differentiate between the 2 test cases and the test cases are executed. Scenario2: fileA: BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE( my_test) { BOOST_CHECK_EQUAL(1,1); } BOOST_AUTO_TEST_SUITE_END() fileB: BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test ) { BOOST_CHECK_EQUAL( 1,1 ); } BOOST_AUTO_TEST_SUITE_END() In the scenario2, I get a compile time error (Error 1 error LNK2005: "public: void __thiscall mySuite::insuite2::test_method(void)" (?test_method@insuite2@mySuite@@QAEXXZ) already defined in BoostUnitTest.obj) which basically suggests that one or more multiply defined symbols are found. Why is the behaviour different in these 2 scenarios? How is Boost able to differenciate between the 2 test cases in Scenario1? Mit freundlichen Grüßen / Best Regards, Hemanth Choudary MV RBEI/ETA1

Threading question
by Davies, John 13 Dec '13

13 Dec '13

I have the following code and it terminates as expected. When I call the destructor it interrupts the thread. But if I change the this_thread::sleep to this_thread::yield the join() never happens and the program hangs. I must be misunderstanding yield. But I really don't want a sleep if possible. Thanks, John MessageQueueHandler::~MessageQueueHandler() { // Terminate the thread pMessageQueueInputThread->interrupt(); pMessageQueueInputThread->join(); delete pMessageQueueInputThread; } void MessageQueueHandler::MessageQueueInputThread() { unsigned int receivedSize; unsigned int priority; char buffer[queueMaximumMessageSize]; boost::this_thread::interruption_enabled(); try { while(1) { // Process all messages in the queue while(inputMessageQueue->try_receive(buffer, queueMaximumMessageSize, receivedSize, priority)) { BaseMessage * msg = reinterpret_cast<BaseMessage*>(buffer); callbackTable->DispatchMessage(msg); boost::this_thread::interruption_point(); } // Give other threads a chance to run // This is also an interruption point boost::this_thread::sleep(boost::posix_time::millisec(50)); <==Here } } catch(boost::thread_interrupted const&) { return; } } ___________________________________ John Davies Contractor Home Respiratory Care Philips Home Healthcare Solutions 1740 Golden Mile Highway Monroeville, PA 15146 Email: john.davies(a)philips.com Fax: 724-387-4109 ________________________________ The information contained in this message may be confidential and legally protected under applicable law.

Fwd: support for bjam projects in IDE
by Witold E Wolski 05 Dec '13

05 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
