To list test suites and test cases of our test exes, I implemented a custom visitor in Boost 1.56 and simply did

const auto& master_ts = but::framework::master_test_suite();
but::traverse_test_tree(master_ts, visitor);

This is broken in 1.64, none of the old methods from the visitor are called, and thus no suites or cases are discovered.

Turns out that the new visit() method is not the one called after all, but still the old ones.

traverse_test_tree() have a new bool arg, which is false by default, and combine with the

fact that the master-test-suite has RS_INVALID(3) in its p_run_status field instead of

RS_ENABLED(1), is_enabled() returned false, and thus traverse_test_tree() returned early.

void

traverse_test_tree( test_suite const& suite, test_tree_visitor& V, bool ignore_status )

{

// skip disabled test suite unless we asked to ignore this condition

if( !ignore_status && !suite.is_enabled() )

return;

...

}

class BOOST_TEST_DECL test_unit { ...

bool is_enabled() const { return p_run_status == RS_ENABLED; }

};

So my fix simply needs to be as below. At least this one was easy, unlike the Boost.PO one... --DD

PS: Then there's also the new --list_content which makes my old code kinda obsolete...

#if (BOOST_VERSION >= 106000)

but::traverse_test_tree(master_ts, visitor, true);

#else

but::traverse_test_tree(master_ts, visitor);

#endif
