I have a unit test case that includes #include <boost/test/auto_unit_test.hpp> #include <boost/test/floating_point_comparison.hpp> // I will try without the unit test namespace // 1.32 using boost::test_toolbox::ostream_test_stream; using boost::test_toolbox::output_test_stream; output_test_stream ostream; This worked in 1.32 (I think--the comment makes it sound as if it shouldn't). But in 1.33 I get error: `output_test_stream' not declared Turning to the documentation, I couldn't find any mention of this navigating the docs for boost.test (including looking at the detailed release notes). However, when I did a site search I found http://www.boost.org/libs/test/doc/components/test_tools/output_test_stream_... That page itself is confusing. the heading is boost::test_tools::ostream_test_stream but the class definition and other material use output_test_stream. The file test/output_test_stream.hpp names the class output test stream. Can anyone clarify what's going on? Either the documentation needs to be tweaked, or I'm confused, or both. Ross
