This change: https://github.com/boostorg/test/commit/1c4533f7654d4c049cc6a34a43a5 c1 0cde5bdd8b#diff-efad11c1b810a644deec92a42abe330e

Oh, sorry about that. Reverting the lines right now.

Actually I like the change - did we need 'framework'?

Anyone using this is perhaps relying on a detail?

(The need for it in the Math test case was to ensure that the BOOST_TEST_MESSAGE("my_message") were actually visible. I think it would be better if messages were visible by default, not something one needs to ask for specially. I also was unconvinced the setting the environment variable BOOST_TEST_MESSAGE worked but I'll check this out and raise a bug report.)

I've finally found this exchange explaining the behaviour. http://boost.2283326.n4.nabble.com/test-Problem-with-BOOST-TEST-MESSAGE-td46... 8.html I think it is very counter-intuitive that messages only emerge to the normal output if there is an error or --log_level="message" And that #define BOOST_TEST_LOG_LEVEL "message" does not appear to have the same effect as --log_level="message" which is also surprising, and in my book a buglet? I suggest that this behaviour should be changed so that BOOST_TEST_MESSAGE *always* produces output. BOOST_AUTO_TEST_CASE(test_message) { BOOST_TEST_MESSAGE("\nTest BOOST_TEST_MESSAGE.\n"); } // BOOST_AUTO_TEST_CASE(test_message) boost_test_message_test.vcxproj -> I:\Cpp\math\x64\Release\boost_test_message_test.exe should output Running 1 test case... Test BOOST_TEST_MESSAGE. *** No errors detected Otherwise I am sure I will not be the only person confused. At the very least the documentation should highlight that ones expectation may not match what actually happens. Paul
