If I correclty understood you I should do smth. similar like this: boost::mutex m; struct thread_safety_test { static void thread_function(boost::barrier& b) { b.wait(); boost::mutex::scoped_lock lock(m); BOOST_CHECK_EQUAL(1,0); } void test_multiple_assertion_faults() { boost::thread_group tg; boost::barrier b(100); for(size_t i=0; i<100; ++i) { tg.create_thread(boost::bind(thread_function, ref(b))); } } }; But unfortunately this does not work. May be I miss smth. here. With Kind Regards, Ovanes On Jan 10, 2008 8:01 PM, Ovanes Markarian wrote:

Thanks for the answer!

I read some post (mainly: you and William Kempf) about Program Execution Monitor and its MT support. This was in 2002/2003 did you manage to solve these issues?

Many thanks, Ovanes

Hello,is Boost.Test framework thread safe in regards to the following

use case:I would like to start multiple threads with some testing tasks. These threads will call boost TestTools functions (BOOST_CHECK... etc.). Is this scenario supported?

No. You will have ti serialize access to the UTF. The simplest way is just use wrapper macro.

Can't comment in these. I never used this class.

| boost::mutex::scoped_lock lock(m); | BOOST_CHECK_EQUAL(1,0); | } | | void test_multiple_assertion_faults() | { | boost::thread_group tg; | boost::barrier b(100); | | for(size_t i=0; i<100; ++i) | { | tg.create_thread(boost::bind(thread_function, ref(b))); | } | } | }; | But unfortunately this does not work.

I am not an expert in MT, but what exactly is the problem?

Do you run is from inside the test case?

Yes. The class specified is passed to the BOOST_CLASS_TEST_CASE( multiple_assertion_faults, thread_safety_test)

The idea of my code is: Create 100 threads and wait until all of them are created. (barrier is used for that).

After all threads were created lock the mutex and produce the assertion fault. In MSVC 7.1 this code crashes after the second call to BOOST_CHECK_EQUAL.

I thought you would be aware of this issue.

Many thanks for your help! Ovanes

Gennadiy, many thanks for your help. The attached file will reproduce the behavior. It depends on boost bind, boost reference_wrapper, boost thread and boost test. Many thanks, Ovanes On Jan 11, 2008 7:48 AM, Gennadiy Rozental wrote:

Can you post complete compilable example? Will I need library for boost threads?
