Impossible to run single test case if name contains whitespace

[Kamil.Witecki@…]

When using boost test with template based test cases it is possible that name create will contain whitespace (all const arguments, rest up to typeid(T).name). For such a name it is impossible to run test case due to bug in library related to parsing of command line arguments assuming ' ' as a separator and cutting name of test case in place of space, even if properly enclosed in quotes in command line.

Simple workaround would be to replace all space characters in name of test case with different one ('_'?). Resolution of ​https://svn.boost.org/trac/boost/ticket/3384 would also solve that problem as well.

#define BOOST_TEST_MAIN 1
#include <boost/test/included/unit_test.hpp>
#include <boost/test/test_case_template.hpp>
#include <boost/mpl/list.hpp>

typedef boost::mpl::list<int, const int> test_types;

BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types )
{
    BOOST_CHECK_EQUAL( sizeof(T), (unsigned)0 );
}

Simple patch replacing ' ' with '_' in test case name.

[hanna@…]

It appears that not only spaces, but also commas cause the same problem, since they appear in std::string typeid(T).name. Patch should be complemented with:

std::replace(full_name.begin(), full_name.end(), boost::is_any_of(" ,"), '_');

Replying to hanna@…:

It appears that not only spaces, but also commas cause the same problem, since they appear in std::string typeid(T).name. Patch should be complemented with:

std::replace(full_name.begin(), full_name.end(), boost::is_any_of(" ,"), '_');

Of course, not std::replace(...) but:

std::replace_if(...)

in this case should be used.
