[boost] [test] Automatic registration of tests created with BOOST_PARAM_TEST_CASE

7 May 2009

      Hi,

I want to create a test that
a) runs the same testing function with different sets of input data 
AND
b) registers automatically

Obviously I can use BOOST_PARAM_TEST_CASE macro for a), but how do I achieve 
b) at the same time? I've been fighting with the problem for many hours and I 
have no idea how to do it. Unfortunately the documentation is very cryptic. 
Here's what I came up with so far:

boost-main.cpp :

#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MAIN
#define BOOST_TEST_MODULE My Master Test Suite
#include <boost/test/unit_test.hpp>

testSomeFunctions.cpp : 

using namespace boost::unit_test;

class DataSet {
  public :
    DataSet( /* params */ ) { /* setup single data set */ }
    ~DataSet( ) { /* teardown single data set */ }
    /* some fields */
}

class DataProvider {
  public :
    DataProvider() {
      dataSet.push_back( new DataSet( /* params */ ) ); /* add more if 
necessary */
    }

    ~DataProvider() { /* free memory*/ }

    std::vector<DataSet*> dataSet;
}

void testMethod( DataSet* data ) {
  /* do something with method that's being tested. Use data somehow */
  BOOST_CHECK( /* assertion */ );
}

BOOST_AUTO_TEST_CASE( TestName ) {
  DataProvider dataProvider;
  test_suite* test = BOOST_TEST_SUITE( "I don't think the name matters" );
  test->add( BOOST_PARAM_TEST_CASE( &testMethod, dataProvider.dataSet.begin(),
      dataProvider.dataSet.end() ) );
  framework::run( test );
}

However this is not correct since test cases created with 
BOOST_PARAM_TEST_CASE are not registered in the master test suite. If one of 
the tests fails I get the following log :

Running 1 test case...
../test/functions/testSomeFunctions.cpp(67): error in "testMethod": check 
data->a == data->b failed [2 != 3]
*** No errors detected

I tried replacing "framework::run( test );" 
with "framework::master_test_suite().add( test );" but that doesn't work at 
all (log says that no errors were detected, while there should be one test 
that fails). I also tried something like this :

BOOST_AUTO_TEST_CASE( ActivationFunctionTest ) {
  DataProvider dataProvider;
  framework::master_test_suite().add( BOOST_PARAM_TEST_CASE(
      &testMethod, dataProvider.dataSet.begin(),
      dataProvider.dataSet.end() ) );
}

but the result is the same (No errors detected). What should I do?
