Re: [Boost-users] Boost.Test Framework to test a DLL

Hi Ovanes,

 

this is, why I added 'printf("Initializing\n"); to init_unit_test() in my DLL. As this is indeed printed before the error message, I think that the lib is found and loaded.

 

Furthermore, if the lib cannot be found, I get:

C:\Projekte\Test\NetControl\bin>console_test_runner --test NetCtrl.dll

Boost.Test framework internal error: unknown reason

 

So it seems that the DLL is loaded and init_unit_test() is invoked, but the test cases are not registered ...

 

Christian

Is there any chance that Boost.Test can not load (find) your DLL? Try to copy console_test_runner into the directory which contains your DLL? Debug DLLs under VC++ have usually a suffix 'D' before .dll. The letter NetCtrl->d<-.dll is probably this suffix. If not, add it, so that the name is NetCtrldD.dll

With Kind Regards,
Ovanes

Hi,

I'm planning to change from CppUnit to Boost.Test for unit testing since
it is now possible to integrate unit tests also in a DLL. Nevertheless I 
do encounter some problems here.

The code is (I guess you'll recognize it):

//----------------------------------------------------------------------
---
#define BOOST_TEST_DYN_LINK
#include <boost/test/unit_test.hpp> 
using namespace boost::unit_test;
BOOST_AUTO_TEST_CASE( test1 )
// void test1()
{
   int i = 0;
   BOOST_CHECK_EQUAL( i, 2 );
}
BOOST_AUTO_TEST_CASE( test2 )
{
   BOOST_CHECKPOINT("About to force division by zero!"); 
   int i = 1, j = 0;
   i = i / j;
}
extern "C" {
__declspec(dllexport) bool
init_unit_test()
{
   printf("Initializing\n");
   framework::master_test_suite().p_name.value = "Test runner test"; 
   // framework::master_test_suite().add( BOOST_TEST_CASE( &test1 ) );
   return true;
}
}
//----------------------------------------------------------------------
---
I the sample (test_runner_test.dll) it works fine but when I use it in 
my DLL I get:
C:\Projekte\Test\NetControl\bin>console_test_runner --test NetCtrld.dll
Initializing
Test setup error: test tree is empty
I also tried the commented version using master_test_suite().add() 
without any change.
Any hint what I can try or how I can debug this?
Thanks,
Christian
